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.

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.
Figure

Flowchart outlining
thehierarchy of legislation, regulation and guidelines that
influence LocalAuthority residual waste management policies and
strategies
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.

Table5 identifies that the majority of residual waste is presentlybeing exported outside the sub-region for disposal, which is neithersustainable nor aligned with the guiding principles of proximity or selfsufficiency.
Another Waste Management Companyrecently has secured planning permission for a new landfill site at Shortwoodnear Bristol which may be availablefor use by the Partnership by 2007/08. It has also received an IPPC permit fromthe Environment Agency.

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.

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.

Figure 5 Total Municipal WasteArisings and destinations for the West of England, 2005/06
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.

Figure 7 The decreasing LATSpermits available to the Partnership Authorities, 1995-2020
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.

make planned service improvements (PSI). The PSI assumes
that the Partnership takes steps toimprove source segregation
performance, for example, by increasing recyclingand composting
through increasing participation in current schemes orcollecting
additional materials. This does not include the construction of
anyresidual treatment facility.

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.

3.7.6.4. 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 .

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

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

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 .
Table

The materials accepted
forrecycling/ reuse at HWRCs and Bring Sites
* Materialsaccepted at
bring sites may vary between locations.
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 .

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
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
.

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.
5.4.4. The Spatial Characteristics of the TechnologyOptions
Figure21 shows the different spatial and physicalcharacteristics of each technology option that was assessed in the OptionsAppraisal process. The modularity of each technology varies considerablyaffecting the flexibility and landtake of the facilities. The table alsoincludes the facility lead in times (the time gap between making a decision andthe facility being operational) and the number that are operating in the UKat present.

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

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

Results of theconsultation

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.
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).

8.2. 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.
