Residual Waste Treatment in Norfolk - Land Full?

Gerry Mole - Head of Environment and Waste

Joel Hull - Project Manager

10 January 2006


The challenge to norfolk
The Challenge to Norfolk

  • Municipal Solid Waste and Household Waste

  • Residual MSW - currently sent to landfill

  • Annual increase in MSW

  • EC Landfill Directive - diverting BMW from landfill

  • Biodegradable Municipal Waste - kitchen waste, green wastes, paper, card, cork, textiles


Where we are now
Where We Are Now

In 2004/05

  • South Norfolk recycled and composted 23.86%

  • Norfolk recycled and composted

    30.75%


Landfill directive targets
Landfill Directive Targets

  • EC Landfill Directive landfill allowance for biodegradable municipal waste (BMW):

    75% of 1995 quantities - 2010

    50% of 1995 quantities - 2013

    35% of 1995 quantities - 2020

  • Requirement for Residual MSW treatment solutions



Focus on 2010 target year
Focus on 2010 Target Year

  • Assuming 3.4% growth, 36% recycling

  • BMW sent to Landfill 210,000t

  • BMW to Landfill Allowance 167,000t

  • Over Allowance 2009/10 43,000t


Implications for waste in 2010
Implications for Waste in 2010

  • Costs in 2005/06: Total £10.1M

  • Estimatedcosts in 2009/10:

    Fines on WDA £150/tonne £6.5M

    Plus landfill costs £42/tonne £13.1M

    Plus landfill tax £30/tonne £9.3M

    Total £28.9M


The norfolk response
The Norfolk Response

  • Phased contract approach for residual waste treatment

  • Phase 1 90,000 -150,000 tpa

    to meet 2010 target

  • Phase 2 up to approx 400,000 tpa to meet 2013/2020 targets

  • Not site or technology specific


Treatment contracts must be
Treatment Contracts Must Be:

  • Affordable to the people of Norfolk

  • Deliverable with regards to technology and planning

  • Flexible and adaptable over time

  • Justifiable in terms of environmental

    performance - the BPEO

  • Compatible with recycling targets


Phase 1 contract a
Phase 1 - ‘Contract A’

  • Contract A for 90,000 -150,000 tpa

  • Aim - 2010 Landfill Directive target

  • Public Private Partnership

  • 10%+ recycling of residual waste

  • 67%+ recovery of residual waste

  • Award contract 2006 for 25 years

  • Plant operational 2009/10


Phase 2
Phase 2

  • For up to approx 400,000tpa

  • Aim - 2013/2020 targets

  • Private Finance Initiative contract?

  • 30%+ recycling of residual waste?

  • 67%+ recovery of residual waste?

  • Award contract 2007/08 for 25 years?

  • Plant operational 2010+?


Residual waste treatment technologies
Residual Waste Treatment Technologies

  • Mechanical Biological Treatment

  • Energy from Waste

  • Anaerobic Digestion

  • Pyrolysis / Gasification / Plasma Arc / Vitrification (ATT)

  • Mechanical Heat Treatment

  • ‘New’ technologies?


Examples of msw treatment
Examples of MSW Treatment

  • Demonstration plants - Defra

  • MBT and Anaerobic Digestion - Leicester

  • EfW - Hampshire, Lincolnshire, Kent

  • Gasification/Pyrolysis - Bristol

  • Europe - extensive examples


Where to find more information
Where to find more information

  • Waste Technology Data Centre run by the Environment Agency:

    www.environment-agency.gov.uk/wtd

  • What types of waste they accept and recycle, what effect they have on the local community, case studies

  • www.defra.gov.uk/environment/waste/wip/newtech/advice.htm


Mechanical biological treatment mbt
Mechanical Biological Treatment (MBT)

  • Generic term for several processes

  • Separates recyclates (metals + glass)

  • Generates soil conditioner (green waste, kitchen waste, card)

  • Generates refuse derived fuel - RDF (paper, plastics, card, textiles)


Mbt and anaerobic digestion
MBT and Anaerobic Digestion

  • Biodegradable fraction from MBT can be treated further by Anaerobic Digestion

  • Generates soil improver

  • Produces gas for energy

  • Stabilized output can be landfilled


Mechanical biological treatment mbt1
Mechanical Biological Treatment (MBT)

  • RDF sent to another facility eg :

    Energy from Waste (EfW) Advanced Thermal Treatment (ATT) Used in co-combustion eg cement kilns

  • RDF capacity?

  • Suitability of soil improver?

  • Rejects and market failures to landfill








Sustainable resource management proposal2
Sustainable Resource Management Proposal

  • MBT and AD facility at Longwater

  • 150,000tpa

  • Norwich City, South Norfolk, parts of Broadland and Great Yarmouth

  • One transfer station


Energy from waste efw
Energy from Waste (EfW)

  • Combustion of waste - small to large scale

  • Generates electricity and / or heat

  • Moving grate - common for MSW

  • Fluidised bed (forced air) - sewage sludge

  • Oscillating kilns - MSW


Energy from waste efw1
Energy from Waste (EfW)

  • Residues - bottom ash, flue gas residue

  • Bottom ash - can be used in aggregate, metals can be recovered

  • Can use RDF

  • Guaranteed high diversion of BMW

  • Waste Incineration Directive?

  • Compatible with recycling?




Energy from waste efw2
Energy from Waste (EfW)

Planning and permitting applications
Planning and Permitting Applications

  • The Planning Authority considers whether a proposed development is appropriate and allows others to help form this view

  • The Environment Agency considers whether a proposed technology / approach is appropriate and allows others to help form this view


Phase 1 progress
Phase 1 - Progress

  • Three bids received in May 2005

  • Bids clarified and evaluated

  • Waste Recycling Group selected as Preferred Bidder
