Anaerobic Digestion – a demonstration programme under the Environmental Transformation Fund
3rd and 4th September 2008
16-18 Mt/y food waste~ 6.7 Mt/y household waste
~ 4.1 Mt/y industrial~ 4.6 Mt/y food service and
supermarkets~ 1-3 Mt/y other commercial
& agricultural•Total: 16-18 Mt/y•~ 4 times our body weight/year
Food waste the hidden resource?

1 tonne food waste = 300 kWh electricity based on 37% efficiency.
Food waste – the hidden resource
Drivers – why AD for the UK?
Climate Change Renewable energy generation capacity Waste reduction & recycling Sustainable farming & diversification Environmental protection & water
management
Feedstock materials Digestion vessel
Biogas
Biofertiliser
Manures and slurriesFood waste
(commercial and domestic)Agricultural Byproducts
Sewage sludge
CO2 + CH4
Anaerobic digestion
Central Government capital support for AD WRAP capital programmes
– Existing technology– Running now – £30M (England, Scotland, Wales & NI)
New ETF programme– Cutting edge technology– £10M (England only)
Demonstrate -
The use of the technology to a wide audienceThe use of cutting edge technologyFeasibility for implementation and use of the technology
ETF – programme objective Demonstrating state of the art or innovative technology technology Increasing efficiency Speed up investment and industry development
To advance the commercial viability of AD technology in the UK by demonstrating improved commercial and technical performance and reduce technology risk for potential investors via demonstration projects.
ETF processETF branded capital grantDelivered by WRAP with support from the Carbon TrustOpen tender invitationDetailed project requirements and evaluation criteriaCapital projects that deliver against key aims
Aim 1 – Maximising cost effective production of biogas
Optimise: inputsdigestion and solids reductiongas production and utilisation
Aim 2 – Maximising environmental benefits from use of anaerobic digestateFertiliser value
Sustainable agriculture
Competitive agricultural sector
Aim 3 – Maximising potential of anaerobic digestion to reduce carbon footprint of food supply chain Closing the loopBiomethane for transportHeat useRefrigerant usesGreen energy
Aim 4 – Maximising opportunity for injection of biomethane into gas grid
Efficient gas production
Gas clean up technology
Grid connection and use
Aim 5 – Maximising potential of anaerobic digestion to reduce carbon footprint of water treatment infrastructureBuild on current resourcesKnowledge and technology transferEfficient use of existing infrastructure e.g. using new feedstocks for the industryCarbon benefits
Successful projects will be….
Those that demonstrate cutting edge technologyThose that deliver strongly against the aims of the programmeThose that are most viable both technologically and economically
Maximise gas production
Maximise environmental protection
Closing the loop
Biomethane to the grid
Water treatment infrastructure
Success depends on
Right peopleRight technologyRight placeAbility to fit the timetable
Claire will explain the process in some more detail
