1.              Executive Summary

The West of England Waste Management and Planning Partnershipconsisting of Bath & North East Somerset, Bristol, North Somerset, andSouth Gloucestershire has developed this Joint Residual Municipal Waste ManagementStrategy (JRMWMS) to define the strategic framework for managing residual wasteover the period 2007 to 2027.

 

The strategy has been developed in response to thesignificant challenges facing the management of municipal waste in the UK; includinglocal, national and international obligations in terms of environmental targetsand policies. Targets forreducing the amount of biodegradable municipal waste (BMW) being sent fordisposal in landfill have been set down by The European Union and there is nowa 'significant risk that local authorities in England will fail to reducetonnages of biodegradable waste sent to landfill by enough to meet the EUtargets for 2010 and 2013. To meet the EU targets the UK will require the construction of waste treatmentand recovery plants, such as mechanical biological treatment (MBT) and energyfrom waste (EfW) facilities'[1].

 

Preparation of this JRMWMS has been underpinned by the following 'vision' agreed by allauthorities:

 

The four local authorities in the West ofEngland area are working together to develop, in consultation with localresidents and other stakeholders, a range of facilities for the treatment ofmunicipal residual waste.

 

These will deliver significant reductions inthe amount of waste, particularly biodegradable waste, being sent to landfillsites. They will also maximise theefficient recovery of resources and encompass environmental, social andeconomic factors.

 

Each local authority will maintain a longterm commitment to increase waste reduction, recycling and composting, and willmove toward a longer term aim of achieving zero waste.

 

The West of England Waste Management and Planning Partnershipauthorities are active in all aspects of waste management particularly wasteminimisation, recycling, and composting. However, even if high rates ofminimisation, recycling and composting are achieved there will still be a largequantity of waste 'left over' that will need to be managed and ultimatelydisposed of. This waste is usually collected from householders in black bags orwheeled bins, or is deposited by them at household waste recycling centres(HWRC) and is described as 'residual waste'. This JRMWMS only considers themanagement of residual waste and it is intended to sit alongside theauthorities' existing waste management strategies, which include schemes forwaste minimisation, reuse and recycling.

 

The overall quantity of waste thePartnership have to manage is expected to rise in the future despite thegeneral trend of reducing waste quantities per household. The majority of thisgrowth is due to an increase in households across the sub-region. By 2026/27the partnership will be required to manage approximately 660,000 tonnes ofMunicipal Solid Waste (an increase of over 100,000 tonnes from 2005/6 levels).

 

The current nature of waste management and future projections for wastearisings and LATS performance has been modelled. This has shown that withoutsome form of secondary waste treatment facility the Partnership will fail tomeet LATS targets in the first target year (2009/10) onwards. This willpotentially lead to the Authorities having to purchase permits or face fineswhich would have a huge financial implication for the Authorities. For example,if the Partnership carried on as they are today in 2026/27 there is likely tobe a LATS deficit of approximately 173,200 tonnes. This could translate into apossible fine for that year in the region of £25,950,000. The authorities aretherefore working together to develop a range of waste facilities to treat thiswaste. These facilities will take some time to procure and are not likely to beoperational before 2013/14, the Authorities are therefore also developingindividual strategies for reducing the quantity of biodegradable municipalwaste going to landfill before this time.

 

Steps have been taken to ensure that the JRMWMSaccords with Government Guidance and that services are delivered to a highstandard, consistent with the principles of best value whilst considering theevaluation of the economic, social and environmental impacts.

 

An in-depth consultation process has been carried out in conjunctionwith the development of the JRMWMS and the Joint Waste Development Plan Document (JWDPD). The Strategyhas therefore been written alongside a very extensive consultation campaignwith the public, the waste management industry and with stakeholders. Theinformation and views obtained during this consultation were considered duringthe decision making process.

 

The strategy does not consider the sites available for the location ofwaste treatment facilities as this process is covered by the Joint WasteDevelopment Plan Document (JWDPD). The main aim of the JWDPD is to define thestrategy for the provision of strategic municipal waste management facilitiesand to allocate sites for waste management facilities for municipal and allother wastes for which allocations have been made in the Regional WasteStrategy for the South West (RWSSW).

 

The JRMWMS considers municipal waste treatment technologies that may besuitable for implementation in the region and subjects a number of options toan appraisal process to produce a preferred option(s). During this process thetechnical performance of each option is modelled/ assessed and also subjected toquantitative and qualitative criteria to assess the environmental, economic andsocial implications of each option.

 

The interim outcome of the process was arange of residual waste treatment combinations with the positive and negativefactors of each identified for consideration.

The threetechnology options emerged with the highest scores which were:

1.    MechanicalTreatment + Thermal Treatment;

2.    Energyfrom Waste; and,

3.   Biological Mechanical Treatment + ThermalTreatment + Landfill.

 

The options will then be assessed on CapitalExpenditure (CAPEX), Operating Expenditure (OPEX) and revenue assessments based onthe size and number of facilities determined in the Technology Model.

 

The same range of waste treatment optionswill be subject to consultation with the public, as part of the Phase TwoConsultation scheduled for early 2007 before the preferred option is chosen toform the Outline Business Case for residual municipal waste managementfacilities.

2.              Introduction

2.1.       The Purpose of this Strategy

 

This Joint Residual MunicipalWaste Management Strategy (JRMWMS) has been produced to create a framework formanaging municipal residual waste generated in the West of England sub-regionin a sustainable manner. The West of England Waste Management and PlanningPartnership (The Partnership) recognise that waste management is changingrapidly and that a local authority's role now includes more than the simplecollection and disposal of waste. National and European legislation is thedriving force behind the need to manage waste in a more sustainable way. Localauthorities are required to reduce the amount of biodegradable waste that theydispose of to landfill or face economic penalties under the Landfill (Scheme Year and Maximum LandfillAmount) Regulations 2004,pursuant to Waste and Emissions Trading Act, 2003.

 

The Partnership was formed in2005 with the intention of creating a strategy to manage residual waste andprovide the infrastructure for its disposal in a more sustainable manner and tomeet increasingly demanding legislation.

 

The Department for theEnvironment, Food and Rural Affairs (DEFRA) policy guidance states that"Long-term strategic planning is vital to all authorities in securing both theinfrastructure and service developments necessary to deliver more sustainablewaste management. It is Government's view that all local authorities shouldeither produce or contribute to a strategy or equivalent."[2]

 

It is fundamental that a wastestrategy is in place to steer all important decisions and commitments. The JRMWMSis intended to provide a structure for the management of residual waste in thelong term and to anticipate longer-term pressures so that they can be plannedfor.

 

This JRMWMS only considers the management of residual waste and it isnot intended to replace each authority's existing waste strategies, whichalready consider source segregation of materials for recycling and composting.This JRMWMS uses a working definition of residual waste as: 'Waste from household sources containing materials that have not been separated and sent forreprocessing'[3]. Inthis case the residual municipal waste includes trade waste which comes underthe authority's control.

 

Currently the majority of theresidual waste produced in the West of England is disposed of to landfillsites, many of which are located outside the region.

 

The JRMWMS acknowledges thatthere should be major changes to our waste management practices and thatmaintaining the 'Status Quo' is not an option. This JRMWMS sets out theobjectives and proposals for waste treatment and disposal that will applyacross the sub-region, and the options for meeting performance standards andtargets.

2.2.       The Strategy Vision

 

The JRMWMS vision is intended to provide a'clear, non technical statement of the direction of travel'2 . The Vision has been adopted to influence and guidethe work and activities of the Partnership and is as follows:

 

The four local authorities in the West of England areaare working together to develop, in consultation with local residents and otherstakeholders, a range of facilities for the treatment of municipal residualwaste.

 

These will deliver significant reductions in theamount of waste, particularly biodegradable waste, being sent to landfill sites. They will also maximise the efficientrecovery of resources and encompass environmental, social and economicfactors.

 

Each local authority will maintain a long termcommitment to increase waste reduction, recycling and composting, and will movetoward a longer term aim of achieving zero waste.

 

2.3.       Who Has Prepared This Strategy?

2.3.1.                  The West of England Waste Management and Planning Partnership

 

This strategy has been preparedby Officers working for all members of the West of England Waste Management andPlanning Partnership, (described as the Partnership from here onwards) inconjunction with Waste Management Consultants, Jacobs. These four unitaryauthorities are statutorily responsible for the collection, treatment,disposal, and planning of municipal waste management.

 

The West of England Waste Management and Planning Partnership

·         South Gloucestershire Council

 

·         Bristol City Council

 

·         North Somerset Council

 

·         Bath & North East Somerset Council

TheAuthorities believe working in Partnership offers economic, environmental andsocial advantages such as:

·        Maximisingeconomies of scale;

·        Minimisingenvironmental impacts;

·        Minimisingtransport requirements; and

·        Providingbest value for the tax payer.

 

The formation of the Partnershipwill also greatly improve the proximity and self sufficiency of wastemanagement in the sub-region. The concepts of Proximity and Self Sufficiencywere introduced in Planning Policy Statement 10[4].Proximity is referred to as: "disposing of waste at the nearest appropriateinstallation, by means of the most appropriate methods and technologies" andself sufficiency as "individuals, communities and organisations takingresponsibility for their waste". The Partnership will consider these twoprinciples in decision making and will aim to maximise proximity and selfsufficiency in waste management.

 

2.4.       The Strategy Scope

The Strategy has been developedbroadly in accordance with Defra guidance on the preparation of Municipal WasteManagement Strategies[5],although the strategy is not typical because it is only includes the managementof residual waste.

2.4.1.                  Residual Waste

ThePartnership was formed to provide a strategy for the management of residualwaste only and therefore this document does not include in-depth analysis ofthe waste minimisation, recycling and composting strategies and relatedinfrastructure that the Authorities have in place. However, this data hasinformed the strategy and has been included in calculations and models offuture residual waste growth. Other wastes and issues that are not consideredby the strategy include:

·        Non controlled agricultural waste;

·        Nuclear and radioactive wastes;

·        Sewage;

·        Waste minimisation & awareness raising;

·        Waste/ recyclate collection services;

·        Cleansing services.

2.4.2.                  Sites for the Location of Waste ManagementFacilities

The Strategy also excludes the consideration of any locations for wastemanagement facilities. In parallel with the preparation of thisstrategy, Waste Planning Officers are developing a Joint Waste Development PlanDocument, which will address this issue. Waste Managers and Planners areworking closely to ensure both the Joint Municipal Residual Waste ManagementStrategy and Joint Waste Development Plan Document will inform and complementeach other.

 

2.5.       Consultation

The Partnership acknowledges thatthis strategy has to be produced with the views and wishes of the localresidents in mind, since the householder has such a crucial role to play in theachievement of new standards in waste management. It is also important that allother organisations and individuals who have a stake in the process areengaged, including commercial waste management companies which will providemany of the services, technologies and investment required to deliver change.

 

The Strategy has therefore beenwritten alongside an extensive consultation campaign with the public, the wastemanagement industry and with stakeholders. The information and views obtainedduring this consultation was included in the decision making process,particularly the Technical Options Appraisal, through which a range ofpreferred waste management options for the Partnership were developed andevaluated. Further details of the consultation process are described in Section2.5 and a separate Strategy Consultation Report[6].

 

2.6.       Strategy Timescale

The JRMWMS is intended to createa pathway for residual municipal waste management for the next 20 years, up to2027 (assuming it is adopted in 2007), in alignment with the Waste DevelopmentPlan Document. However, it is anticipated that waste treatment facilities couldstill be operating for some time after 2027.

 

Waste management is a dynamicarea and there can be uncertainty about legislation and technology beyond theshort to medium term. For this reason certain sections of the JRMWMS will beunder constant review, for example, targets, action plans, and monitoringarrangements. There will inevitably be times when significant changes will needto be made to the JRMWMS to reflect changing commitments and investments. As amatter of protocol the JRMWMS will be fully reviewed every five years by thePartnership.

3.              Where is The Partnership today?

 

This sectionprovides a baseline review of the Partnership authority's current wastemanagement position and includes the following elements:

·        An outline of existing key policy and legalrequirements;

·        Roles and responsibilities of the Authorities;

·        Contextual information about the West of Englandand each Authority;

·        Analysis of waste data;

·        Forward projections of waste quantities; and,

·        Business as usual LATS balance.

 

3.1.       Key Policy and Legal Requirements

 

This section provides an overviewof the current key legal and policy requirements which may impact on residualwaste management. In order for the Partnership to put forward an action planthey will need to ensure that all actions are aligned with the relevantlegislation and focused towards achieving statutory targets identified byGovernment. APPENDIX A- FURTHER RELEVANT LEGISLATION includes a more comprehensive list of other relevantlegislation.

 

Figure1 outlines the hierarchy of legislation,regulation and guidelines that influence Local Authority residual wastemanagement policies and strategies for their areas. Guidelines and codes of practice may not havea statutory basis but they often provide a valuable framework from which localand regional strategies can develop.

3.1.1.    EU Directives

3.1.1.1.              Landfill Directive, 1999

The Landfill Directive was developed as a climate protection measurebecause of concern over the high levels of methane produced by thedecomposition of biodegradable waste in landfills. The directive requires anincreasing amount of municipal waste to be either pre-treated (to reducebiodegradability) or managed by methods other than landfill. The Landfill Directive[7] wastranscribed into UKlaw as The Landfill (England and Wales) Regulations 2002.

 

The Directive sets requirementsto reduce the amount of biodegradable municipal waste (BMW) that can be sent tolandfill. The starting point for the targets is the amount of BMW that wasproduced (not landfilled) in 1995. Each country can then only landfill thefollowing amounts of BMW:

·        by 2010, only 75% of the amount produced in1995;

·        by 2013, that reduces to 50%;

·        by 2020, that reduces to 35%

 

Therefore the amount of wastethat can be landfilled over the next 20 years is tied to the amount produced in1995, even though waste quantities are still rising. This ever increasing gapis producing the greatest force for change in waste management in the UK.

 

A recent study by the NationalAudit Office[8] stated that the increase inrecycling had been offset by the growth in waste produced and that there is "asignificant risk that the targets will not be met". There are also likely to beheavy financial penalties if local authorities do not meet the targets, whichcould be up to £180 million a year

3.1.2.    UK Acts

3.1.2.1.              Waste and Emissions Trading Act (WET), 2003

The Act isintended to facilitate England meeting its Europeanobligations under the Landfill Directive for the diversion of biodegradablewaste from landfill. The Act involves the allocation, by the government, of 'landfillallowances' to waste disposal authorities each year. Authorities can theneither stick to their landfill limits each year, or they can trade theseallowances. High landfilling authorities may need to buy more allowances ifthey expect to landfill more than their limit. Authorities with low landfillrates can sell their surplus allowances to those authorities that may requirethem. The Act sets the statutoryframework to implement a Landfill Allowance Trading Scheme (LATS).

3.1.2.2.              Landfill Allowance Trading Scheme (LATS), 2005

Reflecting the intention of theLandfill Directive the LATS system sees progressively tighter restrictions onthe amount of biodegradable municipal waste - include kitchen waste, green orgarden wastes, paper, card, cork and even some textiles[9] - thatdisposal authorities can landfill.

 

Local authoritieshave been allocated allowances for the amount of BMW they can landfill forevery year of the scheme until 2020. These allowances are tradable, so that high landfillingauthorities can buy more allowances if they expect to landfill more than theallowances they hold. Similarly, authorities with low landfill rates can selltheir surplus allowances.

 

Authorities do not have to tradeallowances. If they want to avoid the complication of trading, they are able tocomply with the regulations so long as they do not landfill more than the totalamount of allowances they hold. This is achieved by increasing reduction,recycling and composting and the development of a facility to process residualwaste. Local authoritiescan also bank unused allowances or borrow from their future allocations withincertain rules.

 

Theconsequences of failing to meet the diversion targets are as follows:

·        The cost of purchasing additional permits (ifavailable);

·        Increased operational costs of haulage/ disposaland landfill tax;

·        Cost of being penalised for exceeding permits(approx £150 tonne); and,

·        Possible increased fines above £150 per tonne inthe 'target years' (2010, 2013, 2020) as fines from Europewill be apportioned between offending authorities, in proportion to theirtonnes landfilled over permits held.

 

In addition, the Chancellor ofthe Exchequer's Landfill tax escalator continues to apply with an ongoingincrease of £3 per tonne per year.

 

The scheme applies to all wastecollected by the local authorities and therefore operates as a disincentive tocollect waste from commercial and industrial premises. However, the Partnershipintends to try and maximise the quantity of non-municipal waste that can berecycled in the region through other means.

3.1.3.                  National Waste Strategies, 2000 (Review 2006)

Waste Strategy 2000[10] waspublished as a response to the recognition that England'swaste management position was unsustainable. The Strategy set down nationalguidance for waste management that all local authorities must have regard. Thestrategy was revised in 2005[11] in response to concerns overthe underpinning decision-making principles and procedures.

 

The strategy focuses on the importance of driving wastemanagement up the waste hierarchy. The waste hierarchy was originally describedin the Waste Framework Directive[12]and stresses that waste prevention and reduction should take priority overother methods of waste management with disposal being the last option. The strategy identified a number of importantnational targets for the recycling and composting of municipal waste, in orderto encourage a shift in waste management practices up the hierarchy.

 

In February 2006 a major reviewof the Waste Strategy 2000[13] waslaunched as a consultation document. The Consultation Document also emphasisedthe importance of the waste hierarchy shown in Figure 2 , which originated from the Waste Framework Directive (1975)[14].

 

Figure 2 The Waste Hierarchy

 

The 2006 consultation documentalso identified a set of revised targets for recycling, recovery, and landfill.The targets from these two strategy documents are summarised in 1 :

Table 1 clearly indicates that it is the Government's intention to introduce moreambitious and challenging targets for Local Authorities with in respect ofrecycling and composting.

 

Some of thekey issues highlighted in the 2006 consultation document were as follows:

·        An increased focus on waste prevention and embeddingthis in the wider Sustainable Consumption and Production Agenda;

·        Viewing waste as a resource and extending arecycling and re-use culture beyond the home to workplaces, shopping andleisure activities;

·        Highlighting sustainable waste management in non-municipalsectors (including commercial & industrial, construction & demolition,mining and quarry waste) with greater integration of planning and procurementbetween municipal and some non municipal waste; and,

·        Securing technological efficient investment inwaste treatment at all stages of the chain.

 

The results of the consultationwere published in August 2006 and were largely supportive of the changes.

3.1.3.1.              Regional and Sub-Regional Policy

A Regional Waste Strategy for the South West[15](RWSSW) was published in October 2004 by the South West Regional Assembly. TheStrategy sets out a fifteen year plan to manage waste sustainably in the regionand input was provided by each authority of the West of England WasteManagement and Planning Partnership. The RWSSW presents measures to manageresidual waste produced by the region.

 

The RWSSW suggests thatapproximately 500-600 new waste facilities of all types will need to be inplace by 2020 including:

·        Facilitiesto process green waste to produce compost;

·        Sortingfacilities for the products that are being recycled;

·        Facilitiesfor mechanical, biological or thermal treatment of residual waste; and

·        Newlandfill capacity as the space in existing landfill is running out.

 

The RWSSW aims to provide aframework such that by the year 2020 over 45% of municipal waste is recycledand reused and that the remaining 55% will be treated or recovered before goingto landfill through thermal or biological/ mechanical treatments. In this wayless than 20% of waste produced in the region will be landfilled.

 

Other 'targets' setout in the strategy include the following indicative annual municipal waste managementcapacities for the Landfill Directive target years shown in Table 2 below.

3.1.3.2.              Waste Guidelines and Codes of Practice

Guidance on theHousehold Waste Recycling Act was published to help Waste CollectionAuthorities take any necessary steps to comply with the Act, whilstacknowledging their freedom to choose the best way of doing so. The newguidance, which followed a consultation held in 2004, highlights good practiceand other sources of information and support that Waste Collection Authoritiesmay find helpful when formulating waste management strategies whilst addressingother statutory requirements such as health and safety.

 

Guidance on Municipal Waste Management Strategies published in July 2005replaces the earlier 2001 Guidance. This Guidance sets out what the governmentexpects from English and Welsh waste disposal authorities and waste collectionauthorities when preparing and updating Municipal Waste Management Strategies(MWMS).

3.1.4.                  Key Planning Policy and Legislation

To increase the amount of wastethat is moved up the waste hierarchy and diverted from landfill will requiremajor investment in waste management facilities. The land use planning systemtherefore has a crucial role to play in the adequate and timely provision ofthese facilities.

 

There has been a revision of national planning policy for sustainablewaste management in PPS10 by the ODPM (now the Department for Communities andLocal Government- DCLG) alongside DEFRA's new policy framework forMWMSs. Provision for the delivery of waste management infrastructure willrequire policies that reflect the needs of the relevant MWMS developed inaccordance with DEFRA guidance, and policies that shape non-waste-relateddevelopment in relation to spatial planning concerns such as transport, housing,economic growth, natural resources and regeneration. The two policy frameworksare therefore closely aligned and this is expected to be re-produced on theground through joint working of planning and waste management departments.

3.1.4.1.              Planning Policy Statement 10, 2005

This documentsets out the key planning objectives and decision making principles that shouldbe adhered to in developing Regional Spatial Strategies and Local DevelopmentDocuments (LDD). It also sets out policies for identifying land for wastemanagement facilities, for identifying suitable sites and areas that fulfil thelocation criteria outlined in the Waste Framework Directive. PPS 10 requiresthat the planning strategies developed by regional and local planning bodiesshould help deliver sustainable development. A key tool for helping to ensurethe sustainability of strategies and plans is Sustainable Appraisal (SA).Thisis identified in PPS 10 as one of the decision-making principles to shape wasteplanning strategies such that they support the Government's planning objectivesfor waste management. As manyauthorities are in a transitional period between old and new systems, PPS10 maysupersede any current planning policies where this is deemed appropriate bythat authority.

 

The principlesset out in PPS10 require the following:

·        RegionalPlanning Bodies (RPB) should prepare Regional Spatial Strategies (RSS), whichaim to provide sufficient opportunity to meet the identified needs of the areafor waste management for all waste streams. Planning authorities should develop Local Development Documents (LDD)which reflects their contribution to delivering the RSS.

·        Wastemanagement should be considered alongside other spatial planning concerns suchas housing and economic growth. Recognition of the contribution of waste management in the developmentof sustainable communities should be noted. This should be integrated withother strategies including Municipal Waste Management Strategies.

·        Clearpolicy objectives should be the basis for planned provision of new capacity andits spatial distribution. Policyobjectives should be in line with the planning policies set out in the PPS andbe linked to measurable indicators of change.

·        Planningstrategies should be shaped by Sustainability Appraisals (incorporatingStrategic Environmental Assessment). SEA is a keycomponent of sustainable development establishing important methods forprotecting the environment and extending opportunities for participationin public policy decision making.

3.1.4.2.              Joint Waste Development Plan Document

In 2004 the Government introducedchanges to the development planning system. Councils are required to prepare aLocal Development Framework, which will replace their existing Local Plans. Thestatutory documents in the Local Development Framework are referred to asDevelopment Plan Documents. Because the collection and management of wastetakes place across local authority boundaries within the West of England, itwas decided that the four Unitary Authorities of Bath and North East Somerset,Bristol City, North Somerset and South Gloucestershire should work together toprepare a Joint Waste Development Plan Document.

 

Whereas the JRMWMS will set out how municipal waste should be managed,the Joint Waste Development Plan Document (JWDPD) will deal with where all waste should be managed.

 

The JWDPD will apportion theamount of municipal and non-municipal waste (mainly Industrial and Commercialwaste) to be managed within each of the four Unitary Authority areas.Importantly, the JWDPD will establish the spatial strategy for the distributionof strategic waste management facilities needed in the West of England if wasteis to be diverted from landfill. It will establish the sustainable wastemanagement principles that will guide waste-related development over the periodto 2026.

 

In order to facilitate thedevelopment of new waste facilities that will be required over the next twentyyears, the JWDPD will identify sites suitable for strategic waste managementpurposes, and where it is not appropriate or possible to identify sites, areasof search and/ or criteria will be identified.

 

The process of preparing adevelopment plan document is set out in the Planning and Compulsory PurchaseAct, 2004 and associated regulations and Government guidance. The key stages inthe preparation of the Joint Waste Development Plan Document are outlined in 3 .

Consultation of the Issues andOptions Document represents an early stage in the preparation of the JointWDPD. The purpose of the document is to generate discussion about wastemanagement and planning in the West of England by seeking views on the issuesfacing the area on how waste should be managed and where the requiredfacilities should be located.

 

The Issues and Options Documentcontains information on the amount of waste likely to be produced in the Westof England over the next two decades, the technologies that are likely to beavailable to manage the waste diverted from landfill, and their spatialimplications for the Joint Waste Development Plan Document, including the broadland use distribution options available to the area.

 

Following the consideration ofresponses to the Issues and Options Document, the next step will be to progressthe Preferred Option(s), which will lead to the preparation of the JWDPD thatwill be submitted to the Secretary of State, and which will be the subject ofan independent examination prior to its adoption around summer 2010.

 

3.2.       Other Waste Streams

Defra's Waste Strategy Review[16]Consultation has shown strong support for better integration between municipaland other waste streams to gain the potential economies of scale from moreintegrated collection, management and recovery of municipal and non-municipalwaste.

 

One of the key objectives of the Partnershipis to consider the capacity in the region to be able to manage both municipaland other waste streams, in-line with the Regional Waste Strategy for theSouth-West (RWSSW). Although the RWSSW does not directly consider commercialwaste it should be noted that depending on market forces the facilitiesprovided for municipal waste may also be suitable for commercial waste.

3.2.1.    Commercial & Industrial Wastes/ Constructionand Demolition Wastes

The review stresses the need torecover more resources from waste, and encourages a more integrated approach towaste management. The consultation also indicates that future targets will beset for the landfill of commercial and industrial waste.

 

Defra's consultation response document considers and encourages theintegration of the commercial and industrial waste streams with the municipalwaste stream in order to offer economies of scale in the provision of recyclingand recovery facilities. This is seen as being particularly useful for wastecreated by Small and Medium Sized Businesses (SMEs) which is excluded frommunicipal collection but where quantities are often too small to be worth aprivate contractor collecting. Waste Collection Authorities (WCA) have a dutyunder section 45(1)(b) of the Environment Act (1990) to arrange for thecollection of commercial waste where requested to do so.

 

However, it needs to be taken into account that commercial waste whichis collected by a WCA itself will be waste which comes into the possession orunder the control of a WCA, and therefore municipal waste, which falls withinthe LATS regime.

 

Construction and demolition waste will also need to bemanaged in the region but it may be more difficult to integrate into themunicipal waste stream due to the different physical properties of the wastes.

 

3.3.       Roles and Responsibilities

Responsibility for waste management in England and Wales is split betweenthe Environment Agency, as waste regulator, and local authorities in theirroles as Waste Collection Authority (WCA) and the Waste Disposal Authority(WDA). Because the Partnership is made up of unitary authorities it is jointlyresponsible both for the collection and disposal of waste. Household waste fromdomestic properties is collected free of charge with the exception of certainwastes (bulky items). In addition, unitary authorities are responsible forinvestigating the potential for recycling in their area and preparing arecycling plan.

 

Unitary authorities are also responsible asWaste Disposal Authorities (WDAs) for ensuring the provision of disposalfacilities in their area for controlled waste. Between 1990 and 2006, thesefacilities had to be operated by the private sector or by a Local AuthorityWaste Disposal Company (LAWDC) rather than by the local authority itself,although this requirement was repealed by the Cleaner Neighbourhood andEnvironment Act, 2005. WDAs must ensure provision for the disposal of all wastecollected in their area by WCAs; provide facilities for householders to deposittheir own waste; and arrange for the disposal of this waste.

 

Government guidance and legislation on developing Joint Municipal WasteStrategies, the National Waste Strategy and Best Value in Waste Management, hasbeen a means of encouraging the joint working between regional authorities andis likely to speed up the change process in the future.

 

Toachieve the aims of the Waste Strategy and to meet the respective targets forrecycling, recovery and diversion, closer working between the partnerauthorities is vital. This will extend to matters contained within future wastemanagement contracts.

3.3.1.    Partnership Working Arrangements

A Project Board comprising ofExecutive Members responsible for waste management and planning has beenestablished, and an Officer Project Team has been identified to take theproject forward and support the Project Board, with officers from eachauthority taking a lead on various activities and tasks required to deliverythe joint strategies.

 

Each Authority has made a formal decision via Cabinet or Executive towork in partnership with the others. The Member Project Board have agreed to anincremental approach to formalising this agreement further which is likely tohappen from the procurement stage onwards. To this end a memorandum ofunderstanding and terms of reference have been agreed by the Member Board, butnot formally signed. Atthe point at which authorities consider formally entering into a jointprocurement of waste treatment facilities it will be appropriate to review thepartnership contracting arrangements. The project organisation and the roles of each entity areshown in Figure 3 .

3.4.       Current Waste Contracts

Existing contracts that thePartnership authorities have agreed for the management and disposal of residualwaste may to some extent restrict the options available to them to manage thisresidual waste in the future. The contract end dates have to be planned forwell in advance as alternative arrangements will take time to organise. It istherefore important that existing contract considerations are integrated intothe decision making process. 4 below identifies the current contracts held by thepartnership authorities for residual waste disposal. It should be noted thatfor each authority the contracts are for residual waste disposal to landfill.

All present contracts will endbetween 2008 and 2010, except for South Gloucestershire's.South Gloucestershire already has a Private FinanceInitiative (PFI) contract in place for the delivery of all waste managementservices. To meet LATS targets beyond this timescale residual waste will haveto be treated to remove or reduce the biodegradability of the waste.

 

In all other cases there is aneed to plan carefully for contract transfers as present contracts are due toexpire in the medium term, and each authority needs to ensure their requiredtreatment capacity is catered for.

 

3.5.       Waste Disposal Infrastructure

As discussed, the four PartnerAuthorities at present all rely very heavily on landfill to dispose of residualwaste. Waste is first bulked up in local transfer stations and is then taken byrail or road to a network of landfill sites.

3.5.1.    Residual Waste Disposal

The transfer stations andlandfills used by the authorities are shown in Table 5 below. Each authority also has a network of householdwaste recycling centres (HWRCs) and bring banks where residual waste andrecyclables are deposited by the public.

3.5.1.1.              Household Waste Recycling Centres

Household Waste Recycling Centres (HWRC) sometimesreferred to as Civic Amenity Sites, are provided for the public to depositresidual waste and recycling which consists of a higher proportion of bulkywaste that cannot be collected. The HWRCs within the partnership area are shownbelow in Table6.

3.5.1.2.              Planned Residual Waste Treatment Facilities

Bristol City Council is working with CompactPower to develop a small scale waste treatment plant for 34,000 tonnes ofresidual waste which has support from the Defra Waste Implementation Programme(WIP) under the New Technologies Demonstrator Programme (NTDP).

 

Compact Power Ltd currentlyoperates a 6,000 tonnes per annum commercial gasification/pyrolysis plant forclinical waste disposal on land forming part of the Avonmouth Refuse TransferStation. The proposed project will generate in excess of 2.5MW of electricityto go into the National Grid and 2 MW of dissipated heat which can be soldlocally.

 

Bristolcurrently transports its kerbside collected garden waste, cardboard and kitchenwaste to Dorset for composting. The City Council isplanning to commission a more local in-vessel composting plant with a capacityof between 25,000 and 30,000 tonnes per annum.

 

South Gloucestershirealso has a large scale In-Vessel Composting (IVC) facility in development withSITA. The facility is due to be operational by February 2008 with a plannedtreatment capacity of 30,000 tonnes per annum and be located at Avonmouth.

 

3.6.       The Political and Socio-Economic Situation inthe West of England

3.6.1.    Overview of the West of England Region

The West of Englandsub-region, which consists of the four partner unitary authorities, has anenviable track record in innovation, creativity and connectivity, and anoutstanding strategic location. Each of the partner authority areas is verydifferent in their physical as well as social and economic geography. Thesedifferences also bring with them very different waste management challenges andthese characteristics need to be taken into account when making decisions aboutwaste management.

 

Over the last ten years, thearea's population has grown faster than the UKaverage to more than one million people. This population growth presents achallenge for the authorities especially when it comes to dealing with thesteadily rising amounts of waste that an expanding population generates.

 

In responseto these challenges the four unitary authorities have formed the West ofEngland Partnership with a range of social, economic and environmentalpartners. It is important to state that this Partnership is an entity separatefrom the West of England Waste Management and Planning Partnership formed forthis project. The West of England Partnership aims to:

·        Realisethe potential of the sub-region and deliver improvements in infrastructure,environment and quality of life;

·        Set avision and clear long-term direction to support the delivery of keysub-regional strategies;

·        Promotethe interests of the sub-region regionally, nationally, and in Europe;

·        Add tothe confidence in the sub-region that attracts public and private investment;

·        Workmore holistically in the interests of the sub-region;

 

Particular attention is given to transport, appropriate housing supply,economic competitiveness and inclusion, and culture, leisure and tourism.


The West of England Partnership haveproduced "Vision 2026" a documentoutlining the partnerships aims and objectives to increase the economicprosperity, improve the quality of life and maintain and upgrade the infrastructureof the region. This document was put out for public consultation in early 2005.The West of England Partnership are at the present time refining the documentas a framework to assist strategic decision making and also developingappropriate delivery plans for the introduction of the documents objectives.

 

The West of England regionalso falls under the jurisdiction of the South West Regional Assembly (SWRA).The assembly is a partnership of councillors from all local authorities in theregion and representatives of various sectors with a role in the region'seconomic, social and environmental well-being. It covers an area of 23,829square kilometres from Gloucestershire, Dorset and Wiltshire to the Isles ofScilly, and represents a population of almost five million. The South WestRegional Assembly exists to promote the economic, social and environmentalwell-being of all who live and work in the region. It reviews and develops wideranging strategies at the regional level to provide an over-arching vision forthe South West.

3.6.1.1.              Brief Socio-economic Comparison of theAuthorities

The nature and characteristics ofeach area are very different as shown in Table7. For example, Bristolis less than a third the size of Bath & North East Somerset but has doublethe population, generating contrasting waste management challenges.

3.6.2.    Bath & North East Somerset

Bath & North East Somerset covers an area of 220 square milesapproximately two thirds of which is green belt. The area has apopulation of 170,000, with approximately 73,500 households. Bathis the largest urban centre (approximate population of 80,000) and is 12 times more densely populated than the rest of thearea. The City of Bath" was added to Unesco's World Heritage List in 1987. By2016 the council population is expected to grow by six per cent, presenting anincreased waste challenge. B&NES also includes the settlements of Keynsham,Midsomer Norton, Radstock, Paulton and the Chew Valley.

 

In 2000 B&NES was awarded BeaconStatus by the government for its waste and recycling services.The Council is committed to recycling and reducing rubbish and set a long termgoal of 'zero waste'. On the 14th July 2005, the Council considered and agreed the Waste Strategy, "Towards Zero Waste 2020", including a 5year Action Plan 2005-2010. The strategy defines zero waste as:

 

"Zero waste isa concept that is spreading throughout the globe. The vision is to reduceconsumption of goods by ensuring that products are made to be reused, repairedor recycled.  What we now call waste should instead be regarded as amixture of resources to be used again to their full potential, not as somethingto be thrown away."

 

The unemployment rate in B&NES was at 3.6% at the end of2005. This was a slight fall on the previous year. The population includes ahigh proportion of skilled workers, the majority of whom commute to the urbancentres of Bristol and Bath.

3.6.3.    Bristol

Bristolhas the largest population of the four unitary authorities that make up thePartnership with a population of approximately 400,000. Bristol'spopulation has remained stable since the early 1990's with only small increasesrecorded each year. The Councilsprojections estimate the population of the city will be approaching the 426,000 mark bythe year 2028. The City's administrative area comprises the city itself,its surrounding inner suburbs and the major industrial area at Avonmouth.

 

The city region has a high percentage of people in knowledge basedindustries compared to UK averages and hasan excellent graduate retention rate. It benefits from a highly skilled pool oflabour, especially at professional and managerial level, enabling the area toaccommodate strong employment growth, particularly in highly skilledoccupations. Nonetheless, there are serious skills gaps in many semi-skilledprofessions affecting the city region. Unemployment in Bristol was approximately5% at the end of 2005.

 

Overall the city-region is relatively buoyant economicallyand has seen significant growth in terms of both population and employment inrecent years. It also, however, has significant pockets of persistent povertyand deprivation both in the inner city and outer public sector housing estates.The Council serves three wards which are in the top 10% most deprived in theCountry (Ashley, Barton Hill and Hartcliffe).

 

There has been significant investment in Bristol's infrastructureover recent years, the redevelopment of the Port and its related transportnetwork and the recent development of the Bristol Science Park, as means toattract high skilled industries into the area, are notable examples.

3.6.4.    North Somerset

The population of North Somerset has increased rapidly over the last 50 years to almost190,000 and it is expected to grow by nearly 13,000 in the next 6 years. North Somerset comprises 144 square miles of rural and urbancommunities, with the largest urban settlements being Weston-super-Mare(72,000), Clevedon (23,000), Nailsea (18,000) and Portishead (18,000). Thepopulation also increases greatly during holiday periods with approximately 4.5million visitors coming to North Somerset each year.

 

Thedistrict contains an international airport and a deep sea west coast port. Thenorthern boundary is formed by the River Avon and Bristol City and the Southern boundary isformed by the River Axe and the Mendip Hills. Approximately two thirds of the area is designated as green belt landand an Area of Outstanding Natural Beauty. North Somersetremains a predominantly rural area with 35 rural parishes and many smallervillages dispersed throughout the region.

 

The unemployment rate in North Somerset stood at 3.1% in1995, which is below the national average. North Somerset is a generally prosperous area,with a growing population. Crime rates and unemployment rates are lower thanaverage, but deprivation statistics do highlight that there are areas in theregion with severe social and economic problems. North Somerset has a high range of inequality, but most of the deprivedareas are concentrated in Weston-super-Mare.

 

The council is tackling theseproblems through education and employment initiatives to provide residents withthe skills they need to find employment. Initiatives such as the Community LearningDevelopment Project have helped 1,200 local people aged 19 and over to attendeducational activities and training courses.

3.6.5.    South Gloucestershire

South Gloucestershireis the fastest-growing area in the South West of England with a population ofover 250,000 people. The majority of the population is concentrated in thenorthern and eastern suburbs of Bristolin areas such as Patchway and Kingswood, although thereare also relatively large population centres at Yate (29,000), Bradley Stoke(20,000) and Thornbury (12,000).

 

The Cotswolds Escarpment formsthe eastern edge of South Gloucestershire and a smallpart of the Cotswolds and the National Trust site of Dyrham Park are also in the area. Some ofthe green belt areas have been taken away by developments like Bradley Stoke inrecent years.

 

Unemployment has fallen sharply from 4.7% in 2005 to0.9% in 2006. The creation of several new business parks in the region hashelped contribute to this fall. The north fringe of Bristol accounts forover 50% (est. 70,000) of the jobs in South Gloucestershire. The Kingswood area has anestimated 30,000 jobs and the Yate/ Chipping Sodbury area 17,000. Away from theBristol suburbs the rateof employment growth has been modest. Some areas, notably Kingswood, have lost jobsin recent years, particularly manufacturing jobs.

While the scale and pace of economic growth hasbrought prosperity to the region it has also created major challenges with asubstantial increase in traffic, pressure on the transport infrastructure andpressure for more housing on green field sites.


3.7.       Analysis of Waste Data

3.7.1.    Current Residual Waste Arisings and Management

In orderto fully understand waste growth and the best way to manage residual waste itis essential that the data available on waste quantities is properly examined.This section gives a current indication of the West of England's waste arisingsand also models how the quantity of residual waste is likely to change over thenext 30 years.

 

Thetotal quantity of municipal waste managed by the Partnership and the variousquantities diverted in 2005/6 through composting and recycling schemes is shownin Table8 and Figure5.

The Partnership authorities'historic reliance on landfill is clearly visible from this information. Thequantity of waste being composted or recycled also varies across each authorityalthough the amount of waste composted should increase for Bristoland North Somerset by 2007/8 due to new collectionservices that have been or will be introduced.

3.7.2.    Historic Waste Growth

The historic municipal wastearisings for each of the Partnership authorities and the West of England as awhole is shown below in Figure6. In order to model the predicted future wastearisings this trend along with socio-economic factors and planned recycling/composting services need to be considered.

Figure 6 Total Historic WasteArisings for the Partnership Authorities

 

A general increase in wastearisings can be noted from Figure6 between 2000 and 2006, although for the Partnershipas a whole there is a decrease in waste arisings from 2004/5 to 2005/6.

3.7.3.    Present LATS Situation

The relevant LATS permits for thelocal authorities in the Partnership are shown in

Figure7 illustrates that all partnership Authorities willneed to significantly decrease the amount of BMW sent for disposal to landfillto meet their LATS targets. An analysis of the Authorities performance againsttheir LATS targets has been modelled in section 3.7.6 .

3.7.4.    Waste Composition

Data relating to the compositionof waste arisings can vary greatly across socio demographics and with seasonalchange. The Partnership Authorities have carried out detailed analysis onresidual, recyclable and compostable materials collected at both kerbside andat household waste recycling centres. Obtaining robust data on waste streamcomposition allows for more precise forecasting of waste arisings. This is animportant aspect when looking at the potential amount of waste to belandfilled, composted or recycled in future years. If this data is notavailable national standards can be applied, however, as recent compositionalstudies have made apparent, waste streams do vary greatly and so nationalstandards can be misleading.

 

North Somerset,South Gloucestershire and Bristol City provided an in depthcompositional waste analysis which have been incorporated into all modelling. Bathand North East Somerset also provided a compositional analysis, however this dataonly gave a single snapshot audit which is unlikely to reflect the annualaverage composition. In the absence of a comprehensive and current totalhousehold waste composition for the Authority, the national standard wastecomposition was used in the modelling. The composition of the each authority'sresidual waste can be updated in the modelling as more recent and reliable databecomes available.

3.7.5.    Forward Projections- Waste Arisings

Predicting future waste arisings is vital to determining future wastemanagement requirements. When considering projections account must be taken ofthe accuracy of the base data, likely projections of household numbers andeconomic growth and the effects of extrapolating data over a 20 year period.For some waste streams, a range is indicated based on the best estimate ofcurrent arisings and predicted future trends.

 

It is considered that the main two factors driving municipal wastegrowth are:

 

·        Number of households - it is generally consideredthat the number of households will directly influence the arisings of waste,therefore if housing numbers are increasing so waste arisings will increase.

 

·        Municipal waste per household - it is consideredthat independent of the number of households, the underlying municipal wasteproduced by each household will change due to factors such as behaviour,socio-demographic factors, education initiatives, affluence and Gross DomesticProduct.

3.7.5.1.              Projected Total waste arisings

Table10 and Figure8 below show the total predicted waste arisings (MSW)for the LATS target years if the status quo (SQ) is maintained. The Status Quo Option simply models thecurrent planned level of source segregation to maintain the existing level ofservice i.e. the performance at 2005/06 continuing throughout the 28 yearmodelled period.

3.7.6.                  The Position of the Partnership in Relation tothe Landfill Allowance Trading Schemeand Targets

When modelling, the guidance (4Ps[17])recommends that authorities assess performance of the 'Do Minimum baselinescenario', a Meet Landfill Allowance Trading Scheme (LATS) targets scenario andan Exceed LATS targets scenario. In this modelling the current sourcesegregation baseline performance has been called the Status Quo (SQ), i.e. theauthorities maintain the existing services. This is a useful baseline on whichto assess changes.

 

Programmed (source-segregation) ServiceImprovements (PSI) that each authority intends to make have been collated andentered into the modelling to determine how source segregation performance willchange over the next 25 to 30 years, for example, whether additional servicesbe rolled out, whether more materials will be targeted for collection, whetherparticipation will increase etc. This establishes the projected futureperformance and enables the calculation of what quantity of waste is sourcesegregated and hence the quantity of residual waste that will need to bemanaged.

 

The Programmed Service Improvements, (PSI)scenario is taken as the future improved source segregation performance i.e.improved over and above the Status Quo baseline, this reflects the 4Ps 'DoMinimum scenario'. The PSI is used as the performance levels that can thenassess the Meet and Exceed Targets scenarios in the technology model.

 

The quantity of residual waste can then bepicked up in the technology model, and applied to the technology options toassess performance and throughput under the Meet and the Exceed Targetscenarios. This includes an assessment of each technology's performance againstBVPI targets for recycling and composting (BVPI 82) and the LATS.

 

The following analysis assessesthe state of each authority and the Partnership in meeting LATS performancetargets under SQ and PSI scenarios.

3.7.6.1.              Bath & North East Somerset Projected LATSPerformance

Figure 9 Bath & North EastSomerset's modelled waste arisings under 'status quo' and 'programmed serviceimprovements' scenarios against LATS targets

3.7.6.2.              BristolProjected LATS Performance

3.7.6.4.              South GloucestershireProjected LATS Performance

Figure 12 South Gloucestershire's modelled waste arisingsunder 'status quo' and 'programmed service improvements' scenarios against LATStargets

3.7.6.5.              The Partnership's Projected LATS Performance

Figure 13 The West of England Partnershipsmodelled waste arisings under 'status quo' and 'programmed serviceimprovements' scenarios against LATS targets

 

The graphs above show that theeach authority will exceed their LATS target by or very soon after the targetyear 2009/10 if their waste management services continue as they are today.Even if planned service improvements (PSIs) are made to waste minimisation andrecycling services any delay in failing LATS targets would be relatively short.This analysis includes all planned collection schemes, some of which are yet tocome online.

 

When waste arisings and LATS targets aremodelled for the Partnership (Figure13 ) there is a predicted shortfall of LATS permits inthe first target year (2009/10) under both SQ and PSI scenarios.

3.7.7.    The Financial Implications of Missing LATSTargets

The financial implication of notmeeting the LATS targets could be severe and even buying permits on the marketis likely to prove very expensive by the 2009/10 target year. By that timepermits could increase in cost from approximately £20/tonne to £100-£150/tonne. If the UKas a whole also failed to meet its targets, a share of the EU fine of £½million per day would be passed down to the Waste Disposal Authoritiescontributing to that failure, to the extent that they contributed.

 

It should also be noted that if the correctnumber of allowances are not available to the

Authorities each will be liable for a cashpenalty from DEFRA of up to £150 per tonne of excess landfill usage.

 

An example of the estimated financialimplications for the Partnership of not meeting the LATS targets is set out in Figure14 .

 

Figure 14 The estimated financialimplications for the Partnership for not meeting the LATS targets (possibleannual fines at £150 per tonne).

3.7.8.    Short-Term Options

Therefore the Partnership has the following short-term optionsavailable:

1. Bank as many spare LATS permits as possible - this will help only innon-target years (2009/10, 2012/13 and 2019/20);

2. Trade permits when possible to meet the LATS allocation and retainthe income to help fund deficit years; and or,

3. Accept all LATS fines and those imposed on the UK by the EU (thisfigure could run into millions of pounds in LATS fines alone).

 

These graphs illustrate the need for thePartnership to invest new facilities to treat residual waste in the long term.However, new facilities are unlikely to be available until at least 2013/14which creates the need for contingency arrangements to divert excess tonnagebetween 2009 and 2013/14.

 

All Authorities need to minimisethe amount of waste produced and to maximise the amount of biodegradable wastethat is composted and therefore diverted from landfill. Each authority'sstrategy to meet LATS for the target year 2009/10 will be outlined in theirindividual Municipal Waste Management Strategy or equivalent plans published.

3.7.9.    The Need for Residual Waste Treatment

From the data above it is clear that the Partnership needs to pursuealternative waste treatment technologies. Highrecycling and composting rates alone will not meet long term targets fordiverting waste from landfill, and further treatment of the residual fractionwill still be required. The meeting of longer term sustainability objectiveswill therefore require the introduction of new waste processing and treatmenttechnologies into the sub-region at one or a number of sites.

 

The sizing and role of any treatmenttechnology has to be carefully considered, so that it does not restrict thepossibility of meeting the increased recycling and composting aspirations.Section 5.4 examines different technologies and facility sizes toproduce a range of preferred technology options for the Partnership.

4.              Where does the partnership want to go and when?

4.1.       Aims, Objectives and Targets

4.1.1.                  The Aim of the JRMWMS

The principle aim of theJRMWMS is develop a sustainable plan for residual waste management in the Westof England.This will enable the Partnership Authorities to meet or exceed thelandfill diversion targets for biodegradable municipal waste (BMW), set down byGovernment.

 

This aim willbe achieved:

·        inconsultation with local residents and special interest groups;

·        in atimely fashion, so as to avoid unnecessary financial penalties and landfill taxcosts;

·        so as toprovide high quality facilities with minimal environmental impact.

4.1.2.                  Objectives

The strategic objectives of theJRMWMS are as follows:

 

OBJECTIVE 1: WASTE TREATMENT

To deliver actual municipalresidual waste treatment facility capacity, on the ground between now and 2013,which will result in:

·        meetingthe financial and environmental objectives of the four waste disposalauthorities in the sub-region, including landfill diversion targets;

·        meetingtonnage/treatment requirements of the Regional Waste Strategy;

·        minimisingwaste disposal cost in the sub-region;

·        moving waste management up the wastehierarchy and developing more sustainable practices.

 

OBJECTIVE 2. FUNDING

To securesufficient funding to implement the JRMWMS.

 

OBJECTIVE 3. CONSULTATION

To provide theopportunity for local residents and community & special interest groups toinform the delivery of the strategic objectives through consultation;

 

OBJECTIVE 4. COMMUNICATION/ INFORMATION DISSEMINATION

To develop and implement an external communications campaign whichwill:-

·        raise awareness of the waste managementchallenges facing the Partnership;

·        raise awareness about the requirement to providetreatment capacity in the West of England region and initiate discussion ontreatment technology options.

·        enable opportunity for participation in theprocess by all residents in the sub-region

4.1.3.                  Targets

As described in Section 3.1 the Partnership have a number of statutory andvoluntary targets set down at a national, regional and local level. ThePartnership will seek to achieve the following targets:

4.1.3.1.              Landfill Directive: Diversion

ThePartnership will seek to meet or exceed Landfill Directive[18]targets for the landfilling of biodegradable municipal waste. This will meanreducing the quantity of Biodegradable Municipal Waste (BMW) sent to landfillin line with the following targets:

·        By 2010 to reduce biodegradable municipal wastelandfilled to 75% of that produced in 1995;

·        By 2013 to reduce biodegradable municipal wastelandfilled to 50% of that produced in 1995;

·        By 2020 to reduce biodegradable municipal wastelandfilled to 35% of that produced in 1995.

 

As a jointlyprocured waste treatment facility is unlikely to be operational until the 2013target year, each Partnership Authority will develop an internal strategy toavoid or manage any LATS compliance challenges before this time through:

·        Waste minimisation;

·        Increased recycling and composting;

·        Banking, borrowing or trading LATS permits;

4.1.3.2.              Waste Strategy 2000: Recovery (BV 82c, i and ii)

The Partnership will seek to contribute to meeting thefollowing municipal waste recovery targets through recovering value fromresidual waste:

·        to recover value from 40% of municipalwaste by 2005;

·        to recover value from 45% of municipalwaste by 2010;

·        to recover value from 67% of municipalwaste by 2015.

 

In this context "Recover" means obtain value from wastesthrough:

·        Recycling;

·        Composting;

·        Other forms of material recovery (suchas anaerobic digestion);

·        Energy recovery (combustion with director indirect use of the energy produced) or from the manufacture and use of arefuse derived fuel in gasification, pyrolysis, or other technologies.

4.1.3.3.              Regional Waste Strategy for the South-West:Waste Management Capacity

The Partnership will seek tocontribute to meeting capacity targets set down in the Regional Waste Strategyfor the South-West. The overall target for the regional strategy is to ensurethat by the year 2020 over 45% of waste is recycled and reused and that lessthan 20% of waste produced in the South-West is landfilled.

 

The Regional Strategy alsoincorporates indicative annual municipal waste management capacities for eachcounty in the south-west including the West of England sub-region. Thesecapacities or targets are shown below in Table13 .

ThePartnership will seek to meet these targets for secondary treatment facilitycapacity and the landfill disposal reductions. However, the Partnership hasalso conducted detailed modelling work presented in section 0 which highlights waste treatment requirementsbased on the size of waste treatment facilities. This data will also beconsidered before setting specific targets for waste treatment capacity in theWest of England.

4.2.       Policies

4.2.1.                  Unitary Authority Policies

Each Unitary Authority has itsown policies on waste management and it is vital that the Partnership'spolicies are aligned with these to ensure a focus and commitment by all membersof the Partnership.

 

The followingguiding principles are incorporated into the policies of the Partnershipauthorities:

·        The Waste Hierarchy;

·        Regional Self Sufficiency;

·        The Proximity Principle.

Table 14 below summarises the key residual waste related policies endorsed by eachAuthority.

* No policy formal adoptedbut presumption is that it is acceptable

 

Bath & North EastSomerset have formally adopted a policy of 'Zero Waste'. The other PartnershipAuthorities embrace much that underpins the concept, and are all workingtowards it in the long term.

4.2.2.                  The Partnership's Policies

There is a Memorandum of Understandingand a set of terms of reference signed by the Partnership authorities. Thissituation will be reviewed regularly to ascertain whether the terms ofreference of the Member Project Board need to be amended in order to moreeffectively deliver the Joint Residual Waste Management Strategy.

 

The authorities have been workingin Partnership towards the shared vision, with regard for the following guidingpolicies on residual waste:

 

POLICY1: LANDFILL DIRECTIVE TARGETS

ThePartnership will use the waste hierarchy as a guiding principle to wastemanagement and landfill will be used as the last option after residual wastetreatment.

Recovery and disposal facilities will be delivered to ensure compliancewith the Waste and Emissions Trading Act, 2003.

 

POLICY2: PARTNERSHIP WORKING

The Authoritieswill work in partnership with each other, the community and the private sectorto maximise the efficient recovery of resources from residual municipal waste.

 

POLICY 3: DELIVERBEST VALUE

The Partnershipwill ensure the delivery of services to a high standard, consistent with theprinciples of best value whilst considering the evaluation of the economic,social and environmental impacts.

 

POLICY 4: LOCAL SUSTAINABILITY

Localsustainability issues will be considered, including opportunities to enhancethe local economy and employment and minimise environmental and trafficimpacts.

 

POLICY5: NATIONAL STRATEGIC OBJECTIVE

The Partnership will work to ensure waste is managedin ways that protect human health and the environment and in particular:

. Without risk to water, air, soil and plants andanimals;

. Without causing a nuisance through noise orodours;

. Without adversely affecting the countryside orplaces of special interest;

. Disposing of waste at the nearest appropriate installation, by means ofthe most appropriate methods and technologies.

 

4.3.       Consultation

4.3.1.                  Public Consultation

An extensive first stage publicconsultation/ awareness raising programme was carried out alongside thedevelopment of this strategy and the Local Development Plan Document. Thepurpose of the consultation was to identify public perception of waste and itspotential as a resource. These views were thenconsidered when setting the objectives for the JRMWMS, which could be testedand reviewed during phase two of the consultation process.

4.3.1.1.              Phase 1 of the Public Consultation- Rubbish orResource Campaign

A Strategic Consultation Forum(SCF) was formed from a wide group of interested parties and stakeholder groupsfrom each Partner Authority to help design and deliver the consultationprogramme and to ensure that all aspects of the community were fully engagedand involved.

 

The public consultation exercisewas launched at The Council House in Bristolon Monday 10th July 2006.Titled 'Rubbish or Resource?' thecampaign invited the public to provide feedback and views on the subject ofresidual waste.

 

During July the 'Rubbish orResource' road show toured shopping centres and venues, together with fivepublic meetings throughout the region to canvass public opinion on how residualwaste could be managed.

 

A survey was designed to quantifyfeedback from the public and this was distributed at all organized events andthrough a specially designed website (www.rubbishorresource.co.uk). As anincentive for filling in the questionnaire each respondent was entered into afree prize draw to win shopping vouchers. The questionnaire survey section ofthe leaflet is reproduced in the associated Hyder Consulting report, whichdetails phase 1 of the consultation process and its results.

 

A number ofmechanisms were used in the consultation to canvass public opinion including:

·        7,000 surveys distributed by hand at shoppingcentres;

·        41 surveys were completed at the EveningMeetings;

·        7,500 postal surveys distributed by localauthorities; and

·        Access to the survey online resulted in thecompletion of 554 surveys.

 

The responses were returned bypost, online and completed on site (e.g. meetings).

 

PublicMeetings were held on the following dates:

·        Bristol- Monday 10th July at the Council House, College Green. BS1 5TR

·        Bathand North East Somerset - Monday 17th July at theGuildhall, Bath. BA1 5AW

·        North Somerset -Wednesday 19th July at the Winter Gardens, Weston Super Mare. BS23 1AQ

·        South Gloucestershire -Wednesday 26th July at Chipping Sodbury Town Hall. BS37 6AD

·        Bristol- Monday 14th August at theCouncil House, College Green. BS1 5TR

These events allowed the publicto put across their views and for the Partnership to inform the public aboutthe process and challenges facing residual waste management. The total number of public attendees at themeetings was 125 as well as Councillors and Council Officers. The breakdown of attendees at each meeting isshown in Table15.

4.3.1.2.              Summary of Issues Highlighted by Phase 1 of theConsultation

The mainpoints highlighted by the public were:

·        All areas could recycle more;

·        Investment in alternatives to landfill isrequired;

·        The Partnership should look at examples of bestpractice from Europe;

·        Respondents "care" what happens to waste and alarge proportion believe further value should be obtained;

·        Respondents are aware of alternatives tolandfill but feel they do not have enough information to make an informedjudgement;

·        Environmental considerations are more importantthan financial considerations when deciding on an alternative to landfill;

·        The preference expressed the for the location offacilities was on brownfield sites, and a larger number of small facilities;

·        Odour and air quality were the most importantissues with regards to site location; although visual impact, traffic and noiseall ranked highly; and

·        A large percentage of respondents indicate aneed to reduce their waste.

4.3.1.3.              Phase 2 of the Public Consultation (2007)

The Partnership intends tocontinue to consult the public and key stakeholders throughout the procurementprocess. One of the key aims of Phase 2 which will be carried out in early 2007will be to gather public opinion on the outcomes from the option appraisalprocess described in section 5.4 .

 

At this stage the JRMWMS willalso be open to consultation and feedback from this process will lead to areview of the strategy, particularly its aims, targets and objectives, whichwill be tested and revised as necessary.

4.3.2.                  Waste Industry Consultation

An Industry Day was held on 20th July 2006 toinform and receive input/ comment from the waste management industry.Representatives from all aspects of the waste industry were invited to attend.

 

Firstly, therepresentatives were given an overview of the project and the consultationprocess. Breakout sessions were then held on the following subjects:

·        Finance

·        Planning

·        Politicalsensitivities / engagement with community

·        Technologies

 

The Options Appraisalprocess was explained to the representatives and a short questionnaire wasdistributed to gather the views of the industry on a number of potentialcriteria to evaluate technology options against. A total of 14 responses werereceived, which were mainly inline with those already discussed. These opinionsand any additional criteria were considered, and used to help determine thelong list of Level 2 sub-criteria and also verify criteria already put forwardby the Partnership.

5.              What doEs the Partnership Need to do to get there?

 

This section evaluates thePartnership's options for achieving the objectives of the project set out inthe previous section. It includes two sections:

 

1) A brief overview of what theAuthorities are doing to promote waste reduction and reuse, and the recycling services they currently manageand those planned for thefuture;

2) A summary of the residual waste Options Appraisal processused to assess and evaluate options forresidual waste management.

 

This waste strategy isprincipally focused on the treatment and disposal of residual waste, however,this cannot be assessed without examining other factors that may influencewaste arisings and composition. Therefore other methods employed by the partnerAuthorities to divert waste from landfill are discussed briefly. More detailson the approaches employed by each authority, is available in their relevantwaste strategies.

5.1.       Waste Reduction and Reuse

Waste growthis a major contributor to waste management problems. However, it is a verydifficult issue to tackle because the underlying reasons appear to be closelyassociated with lifestyle and culture. This issue is not local to thePartnership but is driven by national and international forces. Waste growthappears to have emerged through two principle sources:

·        Excess packaging; and

·        Excessive consumption.

Local Authorities have relativelylittle power to influence these drivers but the Partnership will work toencourage all parties to 'behave' more sustainability, through promotion,education and the provision of services.

5.1.1.    Waste Minimisation Campaigns Currently Supportedby the Partnership Authorities

Currently allthe Partnership Authorities carry out the following actions to promotereduction and reuse:

·        Encourage home composting to reduce the quantityof municipal biodegradable waste (BMW) entering the residual waste stream.

·        Encourage the use of re-usable nappies. The RealNappy Project, run by The Resource Futures has received funding in thepast from the Waste & Resources Action Programme (WRAP) to work in Bath and North EastSomerset, Bristol, South Gloucestershire and North Somerset. As part of theproject Resource Futures employ a number of part time nappy outreach worker.

The four Authorities use numerous other methods of promoting wasteminimisation and recycling as shown in the Table16 below.

Due to the dynamic nature ofwaste management and funding these projects are constantly being updated andnew projects are frequently added. Each Authority has increased resourcesavailable in this area and acknowledges the importance of waste minimisationand re-use. For example, South Gloucestershire have recently established ajoint waste minimisation team with the waste management company SITA, workingto an agreed 2 year communications and marketing plan, which will take forwarda range of initiatives.

 

The Authorities will continue to activelypromote waste minimisation, working to reduce the quantity of waste produced byencouraging the re-use of many materials that would otherwise have beendisposed of to landfill.

 

5.2.       Recycling

The Authorities have also been set targets for recycling bythe Government under Best Value Performance Indicators (BVPI). These indicatorsprovide a way of measuring authorities recycling and composting performance.The Partnership's performance against BVPIs is shown below in 17 .

Table 17 shows that Bath & NE Somerset and South Gloucestershire both met their target for recycling and compostingin 2005/06 and that Bristol and North Somerset did not. Therecycling and composting performance of these two authorities is alreadyimproving significantly due to a number of new services that have recently beenor will be introduced:

·        Bristol's weekly kitchenwaste, cardboard and optional chargeable garden waste collections launched insummer 2006;

·        North Somerset's fortnightly gardenwaste collection service which was launched in February 2006.

 

The establishment of a residualwaste treatment facility would also be likely to improve the best valueperformance indicators for recycling, through the extraction of additionalrecyclates from the residual waste stream.

 

5.2.1.                  Household Waste Recycling Centres

All of the Partner authoritiescollect recycling and residual waste at HWRCs. The location of these centresand the range of materials accepted there are shown in Table18.

5.2.2.                  Bring Sites

Each Authority has a network ofBring Sites where the public are able to deposit a range of materials forrecycling. These tend to be located in car parks or supermarkets and accept anarrower range of materials than HWRCs due to the lack of space available. Therange of materials accepted at Bring Sites is shown in Table 18 .

5.2.3.                  Home Composting

The Partner Authorities allpromote home composting and have implemented a range of schemes to educate andinform the public as outlined in section 5.1.1 . Although at present home composting schemes do notcount towards LATS targets they clearly do reduce the amount of waste thatneeds to be collected and the amount of waste going to landfill, which in turnreduces the landfill tax paid by the Local Authority. All four authoritiesoffer subsidised home composting bins through their websites and/ or at HWRCs.

5.2.4.                  Recyclable Materials from Households throughKerbside Collection

The partnership Authorities allcollect an assortment of recyclable material both at the kerbside and athousehold waste recycling centres. The variety of materials collected and theirassociated service managed by each authority is illustrated below in 19 .

Introduction 2007/08

P

O

O

from winter 2008

 

All four of the authorities havealready or are in the process of introducing complex collection schemes torecycle/ compost as much waste as possible and divert it from landfill.However, even if high rates of composting and recycling are achieved there willstill be a considerable quantity of residual waste that needs to be disposed ofas shown in Section  

5.3.       Landfill

Landfill void space inside theWest of England is very scarce and that there are very few mineral voids thatare geologically suitable for landfill of anything other than inert waste. Forthis reason if the amount of waste being transported out of the region fordisposal is going to decrease, technologies will have to be utilised thatoutput a stable, inert waste. In this way the region could reduce the amount ofwaste exported from the region for disposal through increased self sufficiency.

 

The Joint Waste Development PlanDocument (JWDPD) addresses the issue of landfill capacity in further detail.

 

5.4.       Residual Waste - Options Appraisal

5.4.1.                  Methodology

As part of the West of EnglandWaste Management and Planning Partnership's (the Partnership) waste managementstrategy development for the treatment of residual Municipal Solid Waste (MSW)the Partnership conducted an Options Appraisal (OA) to evaluate a range ofresidual waste treatment technology options available. Figure 15 illustrates in a schematic the process of selecting areference project through an options appraisal process. An outline of theprocess is explained below but further details are contained within APPENDIX C- TECHNICAL OPTIONS APPRAISAL REPORT

 

 

Figure 15 The Options AppraisalProcess

 

The OAprocess, facilitated by Jacobs U.K. Limited (Jacobs) has provided thePartnership Authorities with a model for the seven technology options selected.

 

Eachtechnology option was evaluated against both qualitative and quantitativecriteria - i.e. environmental, socio-economic, technical and financial, inorder to provide a relative ranking of the technology options against eachother.

 

Inorder to provide a process that is transparent, accountable and robust, theselection of the evaluation criteria involved a wide range of stakeholdersthrough consultation. A wide range of stakeholder representatives wereconsulted at key stages of the OA process, including participation at theEvaluation Criteria and Scoring Consultation workshops. In addition to the four Unitary Authority(UA) Executive Members on the Partnership's Member Project Board, appropriateScrutiny Panel Councillors also took part. Representatives from umbrella organisations in the West of England werealso invited for consultation, including environmental interest groups, wasteindustry, regional government and agencies, health trusts and parishcouncils. Stakeholder groups from eachUA's local area were invited for consultation, including housing associations,pensioner's forums, waste management forums, environment interest groups,residents' groups, citizen's panels and local strategic partnerships. Inaddition, the Member Project Board also considered the outcomes from theseinputs and the criteria and weightings. This process is also consideredessential in the engagement of stakeholders and allows their considerations tobe taken into account and allows the stakeholder groups to focus and explorespecific areas of concern.

 

Thetechnology options were ranked against all the Quality Evaluation Criteria at aScoring Consultation Day including the same stakeholder groups invited to theCriteria Consultation Day, as well as Scrutiny Panel Councillors, the outcomesof which were considered by the Member Project Board, which further consideredthe indicative costs of each option, the final product being a ranking of thetechnology options.

 

TheOA process carried out by Jacobs does not serve to draw any conclusion from theevaluation process, but serves to provide further information that can then betaken forward to the Issues and Options Paper[19] and the Joint Residual Municipal WasteManagement Strategy (JRMWMS). This public consultation is being carried out onthe process and outcomes before a preferred technology option is identified andagreed to be taken forward to form an Outline Business Case (OBC) for theprocurement of residual waste management services.

 

The JRMWMS is being produced to createa framework for managing municipal residual waste generated in the West ofEngland sub-region in a sustainable manner. It is fundamental that a wastestrategy is in place to steer all important decisions and commitments. TheJRMWMS is intended to provide a long term structure for the management ofresidual waste and to anticipate longer-term pressures so that they can beplanned for.

 

The OBC is relevant to any major procurementproject as the purpose of the OBC is to support and justify the choice ofservice delivery route as recommended in the JRMWMS and to providedecision-makers with all of the relevant project information to enable approvalto be given.

 

5.4.2.                  Technical Modelling of Waste TreatmentTechnologies

A key elementof the OA is a Technical Options Appraisal, the aims of which are to undertaketechnical modelling of selected residual waste treatment technologies in orderto:

·        Compare their performance against LandfillAllowance Trading Scheme (LATS) biodegradable municipal waste landfilldiversion targets;

·        Identify the recycling and recovery rates likelyto be achieved in conjunction with the current and proposed collection systemsand identify potential additional materials that could be collected ifnecessary;

·        Allow the Partnership to determine the size andtype of facility;

·        Determine the indicative capital and operationalcosts associated with the options;

·        Allow the Partnership to identify a preferredoption and develop a reference case for use in a final OBC;

·        Complete the OBC; and,

·        Assist in the production of the JRMWMS.

The modelling of technologies isintegral to the options appraisal process. Figure16 below illustrates in a schematic the technicalmodelling process undertaken.

Figure 16 The technical modellingprocess

 

As part of the appraisal process,Jacobs were required to forecast future waste arisings of the Partnershipauthorities. Historical data on waste arisings and composition has beenprovided by the Partnership authorities, which has been used, along withhousing projection data to model a potential waste arisings scenario over thenext 30 years.

 

Current source segregation activities thatthe UAs undertake were analysed in detail i.e. kerbside collections, HouseholdWaste Recycling Centres (HWRCs), bring banks etc. The quantity of sourcesegregated material is subtracted from the total MSW to estimate the quantityof residual waste that remains for treatment.

5.4.2.1.              Scenarios

A Status Quo (SQ) scenario and a ProgrammedService Improvement (PSI) Scenario were modelled in the Capture Rate Model. TheSQ option sits alongside the technologies in the Technology Model, whilst thePSI option forms the baseline performance on top of which the technologyoptions (1 to 7) are modelled.

·          SQ - The Partnership carry on as they are today(2005/06) with no changes to future source segregation performance; and,

·        PSI - The Partnership implement all the serviceimprovements that are currently planned beyond 2005/06 i.e. improving sourcesegregation performance.

 

Inclusion of these two scenarios gives acomparative performance for the technologies against the current situation (SQ)and projected future changes (PSI).

 

In order for themodels produced to have an acceptable degree of accuracy in relation tofacilities currently offered by the market, specific technology types andmanufacturers were modelled.

 

The waste treatment technologies modelled reflect technologies thatare operating and proven in the market (not just in the UK), that are beingproposed in local authority contracts at this time, and that are considered tobe bankable and do not have unacceptable risks associated with delivering them.The options are based on the best current available data; however, this doesnot preclude other technologies that may be proven in the future, beingincluded at a later date.

 

For each technology option two scenarioswere then modelled in the Technology Model, the Meet (LATS) Targets and theExceed (LATS) Targets scenarios:

 

·        Underthe Meet Targets scenario the treatment technology is modelled to process theminimum amount of available and appropriate waste throughput required in orderto comply with the Partnership's LATS targets. A 10% buffer was incorporated ontop of the targets as a comfort zone.

·        Underthe Exceed Targets scenario the treatment technology is modelled to process themaximum amount of waste that is available and appropriate. This gives the bestpossible performance against LATS targets.

 

A hypothetical contract period of 28 yearshas been modelled, based on experience with current contracts being negotiated.This 28 year period was applied to the technical modelling.

 

The technology options modelledare shown below in Table20 . A more detailed description ofthe technologies can be found in APPENDIX B- WASTE TREATMENT TECHNOLOGIES

5.4.3.                  Results of the Technology Modelling

The waste technology modellingresults displayed in Figure17 and Figure18 below show that SQ and PSI options both fail to meetLATS targets. This demonstrates the need for a residual waste treatmenttechnology in order to meet the shortfall against LATS targets. The figuresalso show that each technology option (1 to 7), is capable of meeting LATS targetsunder both the Meet and Exceed targets scenarios.

 

The performance of eachtechnology option against BVPI recycling and composting targets (82a and 82b)is shown in Figure19and Figure20.

In addition to the Recycling andComposting BVPI, it should be noted that a BVPI exists for energy recovery,namely BVPI 82c. This OA has not explicitly measured performance against BVPI82c, but has considered energy recovery of technology options in evaluatingagainst other level two sub-criteria, which are explained in the next section.

5.4.5.                  Options Appraisal Evaluation Criteria

In addition to the technical appraisal each waste technology option wasalso evaluated against a series of weighted qualitative and quantitativeassessment criteria including, socio-economic, environmental and financialcriteria.

 

A long list of potential LevelTwo Sub-Criteria were listed against four Level One Criteria (Technical,Environmental, Socio-Economic and Financial) as set out in Table 23 and Table 24 below. This long list was drafted by Jacobs and thePartnership's Waste Management Officers at a meeting on 5 September 2006. Thelong list was developed using Government, ODPM, 4Ps, Defra guidance, experiencefrom a number of options appraisals conducted with other local authorities,feedback from industry and the Sustainability Appraisal indicators provided byERM (Defra appointed external advisors).

 

The industry was invited tofeedback their views on Level One and Level Two sub-criteria via an IndustryConsultation Day held on 20 July 2006. These were used to help determine the long list of LevelTwo sub-criteria.

 

Whilst the Member Project Boardrecommended a short-list of Level Two Sub-criteria to be used in the OA, it wasrecognised that the transparency and robustness of the OA Process would besignificantly enhanced if a wider range of stakeholders were involved in thecriteria short listing and weighting process.

 

Therefore, representatives froma range of stakeholder organisations were briefed on the process for theselection of evaluation criteria at a meeting on 7 September 2006. Attendees were invited tosubmit their initial thoughts on Level Two sub-criteria by email or post. Theinformation and opportunity to participate was also provided to a number ofother stakeholder representatives by email.

 

To provide a further and finalopportunity for input into the Evaluation Criteria selection process, aCriteria Consultation Day was held on 22 September 2006. A wide range of stakeholders were invited toparticipate in the day, they were also provided with the opportunity toparticipate electronically if they could not attend the event.

 

The attendees were asked to shortlist Technical, Environmental andSocio-economic Level Two Evaluation Criteria, and to weight those short-listedcriteria. The results of this short-listing exercise are presented Table 23 , which shows the criteria used in the OptionsAppraisal process; it also shows the percentage weightings proposed bystakeholders at Criteria Consultation Day.

Participants at the CriteriaConsultation Day were not invited to feedback on potential Level Two sub-criteriaunder the Level One financial criterion. It was agreed by the Member ProjectBoard at the meeting of 7 September 2006 that Cost/ finance would be considered exclusively by theMember Project Board. Only one financial Level Two sub-criterion was taken forward,being 'Financial Cost - costs of delivery of each option.'

 

The Member Project Boardconsidered the weighting of Level One criteria i.e. Socio-Economic,Environmental and Technical. An anonymous vote was taken to weight the LevelOne Criteria. The Member Project Board was then presented with the outcome ofLevel One weighting determined at Criteria Consultation Day, in order tocompare their weightings. The Board considered the differences and resolved thefollowing Level One criteria weightings to be taken forward to Scoring Dayshown in Table 24.

Members then considered the LevelZero weighting i.e. Cost versus Quality, where the Quality Level Zero criteriaencompasses the Socio-Economic, Environmental and Technical Level One criteria.

 

A decision to propose theweighting split shown in Table25 was taken by the Member Project Board on 26 September 2006.

5.4.6.                  Scoring Consultation Day

The agreed OA evaluation criteria that comprise the Level Zero Qualitycriterion were used to evaluate each technology option. This process wasconducted at a stakeholder workshop, Scoring Consultation Day, on 12 October 2006, whereparticipants were divided into five groups with every group scoring eachtechnology option against each of the criteria. Technical presentations precededeach scoring session to provide stakeholders with appropriate information anddata on which to base their evaluations.

 

The stakeholders that were invited to participate at ScoringConsultation Day are shown below in Table 26 .

The scores for each group were then entered into a database where theycould be averaged and weighted according to the method set out above and theagreed weightings of evaluation criteria. The outcomes from the process areshown in Figure 22 .

 

Figure 22 Results of theconsultation scoring day against the Level ZeroQuality criterion

 

22 , firstly shows that the SQ option scored poorly anddemonstrated that stakeholders did not believe that this method of wastemanagement was viable in the future. The three technology options that emergedwith the highest scores were:

4.    MechanicalTreatment + Thermal Treatment (63.3);

5.    Energyfrom Waste (58.6);

6.   Biological Mechanical Treatment + ThermalTreatment + Landfill (57.2).

 

The SQ option was evaluated as the poorest against the criteria andtherefore ranked last.

5.4.6.1.              Cost Criterion

The cost of each option has also been modelled in an indicative CostModel. This Cost Model used outputs from the Technology Model, in terms ofprojected facility throughputs. Against a series of cost modelling assumptionsthe capital expenditure, the operating expenditure and the potential revenuesfor each technology option was projected over the 28 year hypothetical contractperiod to determine an indicative service cost in terms of a Net Present Value(£). This service cost included the costs for managing source segregatedmaterials i.e. at kerbside, at HWRCs and at bring banks, though excludescapital expenditure on infrastructure associated with managing these wastes.

 

The Cost criterion 'costs of delivery of each option' was considered ata Member Project Board meeting on 24 October 2006. The indicative Net Present Value (£) foreach technology option is presented in Table27.

5.4.8.                  Next Steps

The outcome of the OA process isa range of residual waste treatment combinations with the positive and negativefactors of each identified for consideration in the JRMWMS. This OA process,the technology options and how they are ranked is subject to consultation withthe public, as part of the Second Stage Consultation scheduled for early 2007. The resulting preferred option(s) can then betaken forward to the OBC.

 

 

5.5.       Service Improvements to be Implemented Before2013/14

As previously discussed theplanned waste treatment facilities are unlikely to be in operation until2013/14. Between now and this date all the Partnership Authorities will misstheir LATS targets at some point (see section 3.7.6 for details). Therefore each Authority has agreed toput in place a separate strategy to minimise the risk of exceeding their LATSallowance. Table31 outlines the measures that have already beenimplemented or are planned by each authority in the near future.

6.              how will The Partnership implEment actions?

In developing a JRMWMS thePartners recognise the importance of generating Action Plans to guide theimplementation of the Strategy. These provide a route map for how theStrategy's objectives and policies will be achieved. The Partners recognisethat changes in waste collection, treatment and disposal arrangements cannot bemade immediately and that new schemes will need to be implemented step by step,over a period of time.

6.1.1.                  Objectives and Policies

The Strategic Objectives andPolicies of the JRMWMS which these Actions Plans seek to achieve are outlinedin Section 4 .

6.2.       Action Plans

The Action Plans form the keystone in theimplementation of the JRMWMS. They set out thebasis for a shift in the way the West of England Region will manage its wastein the future. It is important to set out the changes required to minimise thewaste generated in the region and the opportunities that will stem from a moreeffective and rational approach to waste management. The vision for the West ofEngland is for a resource-efficient culture where waste reduction, reuse andrecycling are a part of everyday life for everyone.

 

The use of Action Plans can help the Strategy to bebrought into effect in a flexible way and to evolve over a number of years inresponse to changing performance and circumstances.

 

These Action Plans will be 'live' documents and willbe kept regularly up to date. Significant changes to Action Plans may trigger achange to the overall Strategy.

 

The overall action plan for the West of England region has been split into four individual sections focusing on:

·        Implementation of policies

·        Working in Partnership

·        Waste reduction and reuse

·        Selection of treatment technologies and facilities

Each Action Plan contains details of activities to beundertaken and by what date. It also includes details of the policies andobjectives to which the plan relates.

 

The Action Plans for achieving the diversion targets will have two keyelements:

 

1.    Achieving 2010targets though recycling and composting systems developed to achieve statutoryperformance standards, which will be developed independently by each unitaryauthority; and

 

2.    Achieving2013/2020 targets by developing new treatment capacity.

6.2.1.                  Implementing Policies

This section sets out key actionsand milestones for the implementation of the Strategy. It focuses on theactions that are required to meet the targets set for the Partnership. These actions will provide the foundation forachievement of the longer term recycling and diversion targets and thereforekey decision points and milestones are also set out.

 

The key policies for the waste strategy have been detailed above and itis the aim of the action plans to prove the route map for their implementation.The timeframes for implementation of the action plans are influenced bygovernment policy and legislation. The Landfill Allowance Trading Scheme (LATS)is an example of the legislation that needs to be taken into consideration whendeveloping Action plans. LATS may provide a particular challenge for thePartnership as it progressively limits the amount of biodegradable waste thatlocal authorities can send to landfill. This scheme has a significant impactfor each of the authorities within the Partnership.

 

It is anticipated thatimplementation of the Polices and targets agreed by the partnership will becoordinated by Waste Minimisation and Waste Strategy Officers from each of thepartners with additional assistance where appropriate. This small group ofofficers from the partnering authorities may act as a steering group for theseactivities and they will be responsible for:

·        Annually reviewing and developing awaste minimisation campaign plan

·        Promoting the waste minimisationstrategy at a strategic level within their own authority

·        Joint project delivery

·        Implementing and disseminating bestpractice

·        Ensuring that measurable and realistictargets are set for each waste minimisation campaign

·        Monitoring achievements and outputsfrom waste minimisation campaigns

·        Ensuring that the promotion andpublicity relating to waste minimisation campaign activities follow theprinciples set out in the Partnership's Communications Strategy.

 

On a regular basis (frequency to be determined) the officerswill report the main activities and successes back to the main Partnershipgroup and polices and targets can be amended or refined to theirrecommendations.

 

It is ultimately theresponsibility of individual Partners to ensure that the implementation of thejoint policies agreed by the Partnership occurs in their respective areas.However the Partnership steering group needs to be aware if partners are havingdifficultly in implementing any of polices and what amendments or actions arerequired to ensure that agreed policies and targets are being implemented byall Partners.

 

The key actions required by the Partnershipare:

·        Regular meetings of the Partnership steeringgroup either on a monthly or every two months are recommended.

·        Regular monitoring, review and feedback onprogressing the group's targets.

6.2.2.                  Working in Partnership

The four unitary authorities havebeen working as a Partnership since March 2005, but a memorandum ofunderstanding is yet to be signed. However the partners have stated theircommitment to working in unison towards the delivery of a joint waste strategyfor the region.

 

Forming and operating partnerships is complex andconsideration needs to be given to the legal issues such as responsibilities,data protection, governance and information sharing protocol. Differentstakeholders within the partnership have different requirements but for localauthorities generally directors of services need to understand the full rangeof issues the partnership is involved in and be given the power to makeexecutive decisions on behalf of their partner authority. Project managers and council officers andpractitioners are expected to be able use the information sharing processesthat evolves through a partnership.

The West of England Waste partnership is still in arelatively early stage but it will be looking to lead by example. ThePartnership will look at opportunities to demonstrate reduction, reuse andrecycling of its own waste, for example by establishing a "buy recycled"procurement policy.

Each member authority of thepartnership has a responsibility to ensure that upon aims and objectives agreedare being enacted. The Appointment of a full time Partnership officer (withsupport) by the Partnership Steering Group would however provide an individualto co-ordinate the actions and aims and assist respective Partners infulfilling their obligations. A Partnership officer would provide a point ofcontact for the partnership for outside organisations, local business and thegeneral public. It is anticipated that a Partnership officer would driveforward many of the key initiatives required by the Partnership. Key actionsand timescales for improving partnership working are highlighted in Table 32 .

6.2.3.                  Waste Reduction and Reuse

Waste reduction and reuse are the top tiers of the waste managementhierarchy. A programme of initiatives will engage households in reducing thevolume of waste needing to be managed in the West of England sub-region. Asecondary benefit is likely to be the awareness raising resulting fromengagement in the initiatives, this is likely to have benefits for theperformance of the recycling and composting aspects of the strategy. However,this is likely to be managed by another team inside each unitary authority,working closely alongside the Waste Strategy group.

 

The management of waste is a growing problem in the West ofEngland Region this is partly due to:

·        More houses being built across the region, and

·        Most households in the region producing morewaste

 

In planning ahead, the Partnershave to predict how much waste might be produced in the future. Reducing theamount of waste being produced and increasing the amount of waste beingrecycled will have a significant impact on the cost of waste management and theneed for new facilities.

 

In order to plan the capacity of waste management facilitiesrequired in the future, the quantity of waste likely to arise during the strategyperiod must be predicted. This work has been completed during the modellingphases. Given recent trends it is likely that waste will continue togrow for the immediate future. The Partners are all involved in initiatives intheir own respective areas. Many of these projects are discrete, stand aloneinitiatives that authorities are only operating only in their own area. ThePartnership will allow joint initiatives between areas to be more effectivelyrun and for national initiatives to be more effectively advertised andencouraged. The greater pool of financial resources available to the Partner'smeans that a larger number of initiatives can more introduced.

6.2.4.                  Selection of Treatment Technologies andFacilities

In order to meet the JRMWMS objectives of meeting landfilldiversion targets of recovering value from residual waste and of minimising theenvironmental impact of final disposal, it will be necessary to put in placearrangements to treat residual waste through one or more of the followingmethods:

·        Mechanical treatment, to separateresidual waste into different categories and to recover materials forrecycling;

·        Biological treatment, to stabilisebiodegradable wastes, to recover materials or biogas and to reduce weight,volume and moisture content;

·        Thermal treatment, to recover heat and/or energy.

 

Selection of the most appropriate technology for a given site, operatoror feedstock is becoming increasingly complex because of the number oftechnologies now available. The Partnership has begun the process of selectinga technology through the Options Appraisal process (Section  

The Partnership also needs tomake a decision over whether they set a target of meeting or exceeding LATStargets for reducing the quantity of biodegradable waste that is landfilled.This will have an affect on the landfill capacity required in the sub-region. Key actions areshown below in Table 33 .

6.3.       Monitoring and Review of Action Plans

The strategy programme identifiesthe anticipated timescale for achieving the Waste Strategy objectives. A number of trigger points are identified inthe strategy programme identified in Section 04. These trigger points are phases where one keytask requires completion in order to commence to the next key phase. Listed below are the trigger points:

 

·        TechnicalOptions Appraisal - Is essential to explore options and arrive at apreferred option for residual waste management.

·        PublicConsultation - The consultation phase must be completed before the JRMWMScan be finalised.

·        FinaliseJRMWMS - The subsequent tasks including procurement cannot be effectivelycompleted until the JRMWMS is approved.

·        PrepareProcurement Action Plan - An action will be required to plan theprocurement process.

·        Developmentand Submission of Outline Business Case - The OBC must be agreed before thePartnership can progress to procurement of the facilities.

·        Procurechosen technologies - A contract is necessary before actual facilities canbe developed.

·        PlanningPermission - A planning consent is required before construction cancommence.

·        ConstructionComplete - Commissioning and operation of a facility will only be possibleonce facility has been fully constructed.

 

These triggerpoints must be monitored as any delay at the interface between tasks couldimpact on later activities significantly.

6.3.1.                  Data Reporting

A commonmethodology and approach to monitoring and performance review isessential. The detailed methodology fordetermining the primary performance indicators for municipal waste managementwill be further developed and published by DEFRA. The aim will be to ensurethat data collection and collation conform to DEFRA and EU requirements. Reporting the information under Waste DataFlow allows for greater integration with data reporting in other parts of the UK. Data reports will be published annually,including information on performance indicators. Waste Data Flow is designedfor local authorities:

·        To allow faster and more accurate datacollection of municipal waste statistics, more regularly and efficiently;

·        To enhance their local data management forreporting and strategic planning purposes; and

·        To offer them streamlined access to performancebenchmarking with other authorities.

The Waste Data Flow does not record asstandard all of the data that would be generated if the partnership proceedswith actions such as increasing home composting, a junk mail initiative or thereal nappies initiatives. The recording of this data will require the Partnersworking together on separate monitoring and recording of any actions orinitiatives they introduce.

 

A list of performance indicators iscontained in APPENDIX D- PERFORMANCE INDICATORS .

6.3.2.                  Strategic Environmental Assessment (SEA)

Provisions and requirements for SEA were established in TheEnvironmental Assessment of Plans and Programmes Regulations (StrategicInstrument) 2004. The Regulations transpose Directive 2001/42/EC of theEuropean Parliament and Council on the assessment of the effects of certainplans and programmes on the environment.

 

SEA is a key component of sustainable developmentestablishing important new methods for protecting the environment and extendingopportunities for participation in public policy decision making. Sustainabledevelopment is also a central theme and key formative tool in the developmentof the Strategy.

 

TheSEA highlights the need to maintain monitoring procedures associated with theStrategy implementation and places emphasis on the appropriate Action Planreview mechanism to ensure that the objectives of sustainable development aremaintained.

6.4.       IndicativeProcurement Timetable

 

Figure25 below outlines an approximate timetable for theprocurement of waste management facilities. This timetable will be updatedregularly to ensure it reflects and changes.

 

Figure 25 An indicative timetablefor the procurement of waste management facilities

6.5.       JRMWMSReview

As a matter of protocol theJRMWMS will be fully reviewed every five years by the Partnership.

 

A Strategic EnvironmentalAssessment (SEA) will be carried out on the JRMWMS and it will be redraftedafter this review to reflect the outcomes.

 

6.6.       Risk Assessment

A basic risk assessment (Table 34 ) has been undertaken on the action plans toidentify key risks early in the process through which we hope to minimise risksand put mitigation methods in place. The risk register illustrates the numerousrisks associated with this complex project and the methods the Partnership willput in place to manage these risks throughout the process.

Mitigation/ Controls

Change in legislation

Any change in legislation (planning, waste etc) could have a significant impact on the project.

The Partnership will monitor possible future changes in legislation and assess its impact. Flexibility may also be of benefit re. sites, technologies etc.

Change in Strategy targets

Regional and national targets could change due to review. Therefore the chosen technologies may not be able to deliver new targets.

Strategy will be robust enough to take account of changes in targets; Technologies chosen will be flexible and adaptable and give required targets without utilising 100% of their capacity.

Changes in Growth Rates or waste composition

Changes in the growth rate or the composition of the waste may have a significant impact on the technologies chosen.

Technologies chosen will not be reliant on a single waste type and will adaptable enough to adjust to fluctuation in the quantities and types of wastes available.

Under performance of recycling initiatives

If recycling collection initiatives are unsuccessful the Partnership could be left with more residual waste than was anticipated to deal with.

Chosen technologies and facility sites will be selected with the capacity to handle greater volumes of waste than would be anticipated if the collection systems were successful.

Changes to definitions in BVPI's

Definitions amended over time could mean the chosen technologies are unable to deliver targets.

The partnership will use the most up-to-date BVPI's; these will be monitored for change and any corrective actions proposed as early as possible. Targets have been set to allow greater performance than required.

Changes to LATS

LATS Review in 2007- Could affect optimal project timings

Strategy will be adaptable, to allow changes in policies following the LATS review. Project target dates will be regularly reviewed.

Site selection/ availability

Sites may be deleted from the Joint Development Document because they are not considered the 'best' site.

Suitable sites may not be available due to acquisition costs/ problems.

Contingency sites will be assessed for suitability. Partnerships between local authorities will help in the acquisition of sites. A continuous liaison with the local planning authority will be maintained. Selected sites will be fully investigated in terms of cost and suitability.

Planning

Planning permission will be required for all sites. Delays, refusals, or enquiries will affect the process.

Target dates will be flexible to allow for alterations due to planning processes. All parties involved will be advised of the planning process. A continuous liaison with the local planning authority will be maintained.

Options Appraisal

Need to ensure the options appraisal process is sufficiently robust and will stand up to scrutiny.

Process will be fully researched and checked before being confirmed. Full explanations of each option and the advantages will be given

Waste Management licences/ PPC permits

The appropriate permits will be required at the 'right' timings for all waste sites and processes.

Permits will be applied for in advance of deadlines. Progress of each site/process will be monitored carefully

Changes in waste collection strategies

Changes to collections may change the composition of the residual waste which may mean processes are rendered ineffective.

Changes will be investigated before implementation. Changes that are already being proposed will be considered as possible.

Chosen technology and performance

Several of the technology options are unproven in the UK. Factors such as the diversion rate from landfill and markets for outputs may be critical.

Technologies chosen will be proven within a similar country to the UK. They will be suitable for the desired diversion rates and markets, but allow for changes in requirements.

Delays in obtaining approvals

Any delays in approvals could have serious cost delays.

Applications for approvals will be thorough, and budget will allow for possible problems.

Insurances

Insurance for innovative technologies may be difficult and expensive to obtain.

Insurance will be considered when choosing the best technologies (using Best Available Technique). The cost/benefit equation will be considered for each.

Partnership do not agree on Preferred Options

If agreement cannot be reached on the chosen technologies there may be serious delay or project collapse.

A mutual agreement will be reached as quickly as possible. Each technology will be reviewed for advantages and benefits vs. problems. The strategy will be flexible enough to allow for this.

7.              ANNEX A -FURTHER RELEVANT LEGISLATION

7.1.1.    EU Directives and Strategies

7.1.1.1.                     Directive on Waste (Waste Framework Directive),(75/442/EEC, as amended)

Known as the WasteFramework Directive, the Directive establishes a framework for the managementof waste across the European Community. It also defines certain terms, such as'waste', 'recovery' and 'disposal', to ensure that a uniform approach is takenacross the EU. The Directive requires Member States to:

·        give priority to waste prevention and encouragereuse and recovery of waste;

·        ensure that waste is recovered or disposed ofwithout endangering human health and without using processes which could harmthe environment;

·        prohibit the uncontrolled disposal of waste, ensurethat waste management activities are permitted (unless specifically exempt);

·        establish an integrated and adequate network ofdisposal installations;

·        prepare waste management plans;

·        ensure that the cost of disposal is borne by thewaste holder in accordance with the polluter pays principle; and

·        ensure that waste carriers are registered.

7.1.1.2.                     WEEE Directive

The WEEE (Waste Electronic and ElectricalEquipment) Directive (2002/96/EC) provides a framework for the control ofElectronic and Electrical Waste. The aimof the Directive is to reduce the quantity of waste from electrical andelectronic equipment and increase its re-use, recovery and recycling. It isintended that by 31 December 2006, the UK must have reacheda rate of separate WEEE collection of four kilograms per inhabitant per yearfrom private households. The Directive requires a further target to beestablished by 31 December 2008. This directive is complemented by the RoHS(Restriction of Hazardous Substances) Directive(2002/95/EC). This is to obligeWEEE producers to use safe materials when constructing their products so end-of- life exposure to hazardous substances is minimal. The Directives objectives are to:

·        Implementsystems for separate collection of WEEE;

·        Enhanceproduct design for the environment to comply with RoHS;

·        Chargecompanies to return WEEE for recycling i.e. producer responsibility forrecovery and financing of WEEE collection;

·        Treatand recover WEEE using Best Available Technique (BAT) at adequate treatmentfacilities; and

·        Makeinformation available to consumers, with clear recycling symbols on electricaland electronic products.

 

This is likely to impact on Local Authorities who may be asked tocooperate with producers to help collect WEEE that is currently in the residualwaste stream.

7.1.1.3.                     The Integrated Pollution Prevention &Control (IPPC) Directive

The Integrated Pollution Prevention andControl (IPPC) Directive, (96/61/EC), aims to protect the environment frompollution arising from industrial activities including certain types of wastefacilities. The Best Available Techniques (BAT) concept is used to minimiseemissions to the air, water or land. It also focuses attention on techniques tomake best use of resources, raw materials and energy and to minimise waste. Theactivities listed for control with this Directive are:

·        Landfills receiving more than 10 tonnes per dayor with a total capacity exceeding 25,000 tonnes (excludes landfills of inertwaste);

·        Installations for the disposal or recovery ofhazardous wastes with a capacity exceeding 10 tonnes per day;

·        Installations for the incineration of municipalwaste with a capacity exceeding 3 tonnes per hour; and,

·        Installations for the disposal of non- hazardouswaste with a capacity exceeding 50 tonnes per day.

 

The Directive has beenimplemented in Englandthrough the Pollution Prevention and Control (Englandand Wales)Regulations 2000 as amended and will require certain residual waste managementfacilities to comply with its requirements.

7.1.1.4.                     The Waste Incineration Directive (WID), 2000

This Directive aims to minimise impact to the environment and humanhealth from the process of incineration. This could be a result of emissions toair, soil, surface and ground water. It applies to all new installations fromDecember 2002, and to installations that already existed at the time theDirective was ratified from December 2005. This Directive covers bothincineration and co-incineration plants and incorporates operational, controland monitoring requirements for substances released into the air.

 

WID will most likely apply to any thermal treatment options underconsideration and/or any third party treatment capacity considered by thepartnership.

7.1.1.5.                     EU Thematic Waste Strategy on the Prevention andRecycling of Waste, 2005

This Europeanstrategy is concerned with the environmental impact of emissions from poorlymanaged waste and inefficient consumption and production patterns.Additionally, the Strategy intends to encourage more recycling within memberstates. The main elements of theproposed new strategy are:

·        Life-cycleapproach: The strategy proposes to look beyond the pollution caused bywaste to consider its potential contribution to a more sustainable use ofnatural resources and raw materials. This aspect is dealt with in a separatestrategy on the sustainable use of natural resources

·        Prevention: Member states will be required to develop waste prevention policies that will"reach out to the individuals and businesses" responsible for wastegenerated in the first place. These will have to be adopted within three yearsfollowing the adoption of the revised waste framework directive. Follow-upreports will have to be submitted every three years afterwards. 

·        Recycling:EU-wide environmental standards on recycling will be adopted to "supportthe development of an EU market for secondary (recycled) materials."

·        Simplifyingexisting legislation: This is also a major priority which will apply alongthe principles of the Commission's 'better regulation' initiative.

·        Targets:The new strategy does not impose specific waste recycling or preventiontargets. The Commission therefore says it is "not expected to result inany quantifiable financial costs" on member states and businesses.

·        Incineration:A revision of the IPPC Directive (Integrated Pollution Prevention and Control)will be tabled that will set "an ambitious benchmark" to improveenergy recovery from municipal incinerators. The Commission says the new energyefficiency benchmark "will determine whether an incinerator can beidentified as a recovery facility instead of a disposal facility."

 

The ThematicStrategy is coupled with a review of the Waste Framework Directive (75/442/EEC as amended by 91/156/EEC and96/59/EC). Proposed amendmentsto the Waste Framework Directive are currently being discussed with MemberStates. The revised Waste Framework Directive is likely to include thefollowing:

·        Definition of Waste: Theconcept of a material or product becoming a waste when discarded will remain.However clarification is likely to be provided, on a waste specific basis, toidentify when certain waste streams will cease to be classified as wastes.

·        Definition of Recovery: Arevised definition of recovery is proposed. Municipal incineration is likely tobe considered as recovery which would reverse a decision of the European Courtof Justice dating from 2003. Policy that prioritises the regeneration of wasteoils will be removed.

·        Hazardous Waste: It is proposed that the Hazardous WasteDirective be integrated into the revised Waste Framework Directive.

·        Best Available Technique (BAT): The concept of BAT will be incorporated tobring the Directive in line with Integrated Pollution Prevention and Control.

7.1.2.    UKActs

7.1.2.1.                     Household Waste Recycling Act, 2000

This Act requires collection authorities to uplift atleast two types of recyclable wastes from all households in their area by 31st December 2010. The onlycircumstances in which they do not have to comply would be where the cost ofdoing so was unreasonably high or where comparable alternative arrangements areavailable. This act does not set specific recovery targets or specificwaste materials that must be uplifted for individual authorities.

7.1.2.2.                     Waste Minimisation Act, 1998

This act gave Local Authoritiespowers to take steps towards minimising the generation of controlled wastes.The local authorities have a statutory duty to increase the quantity ofhousehold waste being recycled.

7.1.2.3.                     Animal By-Products Regulations 2003

Theseregulations came into operation on 1 July 2003 and provide the powers necessary to enforce the EU AnimalBy-Products Regulation No. 1774/2002 which lays down health rules concerninganimal by-products. The Animal By-Products Regulation tightens the rules on theprocessing, use, disposal, trade and import of animal by-products. Its mainobjectives are as follows:

·        ban the routine burial of fallen stock;

·        allow the treatment of animal by-products inapproved composting or biogas plants;

·        maintain the existing UK ban on swillfeeding;

·        introduce controls on animal carcase incinerators;and

·        require the treatment of previously uncontrolledanimal by-products such as blood and feathers.

The regulationsaffect kitchen waste produced by households which may contain animalby-products. Therefore local authorities which collect this waste must takeaccount of these Regulations when processing the waste.

The regulations dictate that a two-stagecomposting system must be employed for mixed green and kitchen wastes:

·        Thefirst stage must be enclosed (though both stages can be achieved in the sameenclosure);

·        Materialmust reach a minimum internal temperature of 60oC for a minimum oftwo days, with maximum particle size of 40mm;

·        For thematuration stage a minimum of eight days is required for housed or openwindrows, and must take place on the same site (unless exceptionalcircumstances prevail);

·        Aminimum temperature of 60oC for at least two days prior to eachturn, and also following the third turn (i.e. at least three turns means thatthe 60oC/two days temperature standard must be achieved at leastfour times).

There are a number of technologies on themarket that can achieve this standard including In-Vessel Composting systems(IVC).

8.              ANNEX B- WASTETREATMENT TECHNOLOGIES

8.1.       Introduction

There are a numberof waste treatment technologies available for the treatment of residualmunicipal waste that were modelled for the Partnership and were assessed in theoptions appraisal process outlined in Section 5.4.

8.2.       Description of Technology Options

8.2.1.        Option: SQ

The Status QuoOption simply models the current planned level of source segregation tomaintain the existing level of service i.e. the performance at 2005/06continuing throughout the 28 year modelled period.

8.2.2.        Option: PSI

The Programmed Service Improvements Option assumes that the Partnership takes steps to improve sourcesegregation performance, for example, by increasing recycling and compostingthrough increasing participation in current schemes or collecting additionalmaterials. This does not include the construction of any residual treatmentfacility. This option is useful as a comparison against other options and willalso demonstrate the need for the project by presenting the performance of thisoption against LATS targets. The PSI Option represents the baseline sourcesegregation performance and is used as the baseline model for the technologyoptions 1 to 7.

8.2.3.        Option 1: Mechanical Treatment; Energy fromWaste

The residual wastein this option is passed through a mechanical treatment process, whichprimarily removes oversize and contraries. The remaining materials areprocessed at the EfW facility, which is modelled on the mass burn / movinggrate technology. The waste is combustedto produce steam and electricity and the ash residue produced is landfilled. Inthe majority of UK operating facilities, ferrous and non-ferrous metals are typicallyremoved after the thermal treatment, however, they may be removed at the startof the process and therein count towards BVPI recycling targets. There areissues over product quality, which improves post thermal treatment, which wouldneed to be considered by the operator.

8.2.4.        Option 2: Biological Mechanical Treatment; 3rdParty Thermal Treatment of SRF; In-Vessel Composting of waste derived compost

This option involves the shredding of residual waste to produce ahomogenous material which is then placed in contiguous windrows where itundergoes aerobic fermentation. At the end of this process, the mass of thewaste is reduced and the material is stabilised and sanitised. The waste thenundergoes a mechanical separating process where ferrous, glass and stone,compostable, and non-ferrous fractions are removed. The compostable materialcan then be sent to an in-vessel composting facility for further process andstabilisation. The remaining material forms a Sold Recovered Fuel (SRF) thatcan be sent to a thermal treatment process (e.g. gasification) which producesenergy and a stable output that will go to landfill.

8.2.5.        Option 3: Mechanical Biological Treatment; 3rdParty Thermal Treatment of SRF; Landfill of stabilised output

This technology issimilar to BMT in that the waste undergoes both mechanical and biologicaltreatment, but in a different sequence. Incoming waste is first screened and passedthrough a trommel screen to separate out fractions. In this way a combinationof metals, plastics, paper and inerts are recovered from the waste stream aheadof the composting stage. The oversize rejects from the trommel screen areconveyed to a skip for disposal. The separated paper and plastic can then forman SRF and be sent to a thermal treatment technology or be put back into thesystem to be mixed with the waste that is stabilised.

The remaining material is then moved to a hall where it is turnedautomatically by the system for a period of approximately 6-7 weeks stabilisingthe waste by reducing its biodegradability content. The resulting outputmaterial can then be landfilled.

 

8.2.6.        Option4: Autoclave + Anaerobic Digestion of Fibres

This option isbased on an autoclave and treatment of the output material though a AnaerobicDigestion process. Residual waste is loaded into a rotating autoclave (sealedcylinder) and using steam treatment technology the biodegradable fraction ofthe waste is broken down into a homogeneous organic "fibre". The processoutputs are sanitised secondary recyclates e.g. metals and plastics forre-manufacture and an organic 'recyclable' fibre.

 

The fibre is then passed to an Anaerobic Digestionprocess,where the organic waste is liquefied, heated and broken down by bacteria. Themethane gas produced by the digestion process can be harnessed and used togenerate electricity. The resulting output is a 'digestate' product which canbe marketed as a compost soil improver.

8.2.7.        Option 5: Mechanical Treatment; 3rdParty Thermal Treatment of SRF; Anaerobic Digestion of waste derived compost;maturation of digested compost product

The residual wastefirstly undergoes the mechanical treatment stage where mixed waste is fed into a 'ballmill', which grinds it down into smaller pieces. The ball mill comprises of alarge steel drum containing numerous 5.5 kilogram steel balls, which slowlyrotates, breaking down the waste. The waste can then be sorted and processedinto metals for recycling, organic material for further processing and paperand plastics which will from a Solid Refuse Fuel (SRF). The SRF can then bepassed to a third party for thermal treatment (e.g. gasification).

 

The residues from this process (approx 20%) which consists of glass,stones etc is likely to be sent to landfill as it does not have an applicationat the present time.


An Organic fraction from the ball mill process is fed into an AnaerobicDigestion process for further treatment. Anaerobic Digestion is carried outwithin sealed, cylindrical digestion tanks, where the organic waste isliquefied, heated and broken down by bacteria. The methane gas produced by thedigestion process in the tanks can be harnessed and used to generateelectricity. The resulting output is a 'digestate' product which can bemarketed for agricultural use.

8.2.8.        Option 6: Autoclave; Thermal Treatment of Fibre

This option isbased on an autoclave and the subsequent treatment of the output material in athermal treatment process such as pyrolysis or gasification. Residual waste isloaded into a rotating autoclave (sealed cylinder) and using steam treatmenttechnology the waste is broken down into its organic and inorganic elements.The process outputs are sanitised secondary recyclates e.g. metals and plasticsfor re-manufacture and a 'recyclable' fibre.

 

The fibre is then passed to a thermal treatmentprocess such as pyrolysis or gasification which thermally decomposes thematerial to produce liquid, gaseous and/or solid fuels and a residue which willrequire landfill disposal.

 

8.2.9.        Option 7: Pyrolysis / Gasification (with fuelpreparation)

The residual waste in this option is put through amechanical treatment process, which prepares the waste for combustion. The remaining materials are processed at aPyrolysis / Gasification facility. Thewaste is combusted to produce electricity and the ash residue produced is sentto landfill.

10.        ANNEX D-PERFORMANCE INDICATORS

10.1.   Monitoringand Measurement

Regular monitoring and measurement of progress towardsachieving the Waste Strategy 2000 Targets is fundamental to the success of theJRMWMS. The partner authorities arecommitted to:

·        monitoring a number of agreed Best ValuePerformance Indicators (BVPIs);

·        validating the data used as the basis of theBVPIs;

·        collating the information quarterly and makingit available to the DEFRA in accordance with Waste Data Flow;

·        checking overall performance against plannedlevels, and,

·        implementing corrective actions as appropriatewhere it is clear that performance is falling significantly behind the plannedlevels.

10.1.1.    Best Value Performance Indicators

The BVPI's form the foundation of annual performancereviews undertaken by the West of England Waste Management and PlanningPartnership and entail:

·        quality assurance checks on the monitoringresults submitted by the partner authorities;

·        reviewing in detail progress towards meeting allof the targets;

·        proposing any corrective actions and/or planmodifications, which may be required; and,

·        producing an annual performance review reportand making this generally available.

 

A list of the BVPIs for municipal wastesthat need to be taken into consideration by the Partnership is set out below.

·        82a -household waste percentage recycled;

·        82b -household waste percentage composted;

·        82c -household waste percentage of heat, power and other energy recovered;

·        82d -household waste percentage landfilled;

·        84 - kgof household waste collected per head;

·        86 -Cost of waste collection per household;

·        87 -Cost of waste disposal per tonne for municipal waste;

·        91 -Percentage population served by kerbside collection or within 1km of recyclingcentre;

·        199 - Local street and environmental cleanliness;

 

The success of the Waste Minimisation Strategy will bemeasured by:

·        The achievement of the JMWMS wastereduction targets;

·        The success of waste reduction schemessuch as the real nappy initiative or home composting;

·        The achievement of government targetsand a corresponding reduction in the amount collected over time - notably BVPI84 (Kg of household waste collected per head);

·        The achievement of the campaignspecific targets as set out for each campaign or initiative in the wasteminimisation action plan;

·        The achievement of targets and aimswithin set timescales;

·        The successful identification andsubsequent planning approval for selected facility sites;

·        The impact of future fiscal measures

 

An annual report will be produced setting out progresstowards these targets and changes to the campaign activity in light of thefindings.
