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?

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
1 tonne food waste = 300 kWh electricity based on 37% efficiency.
Food waste – the hidden resource

But this programme is not just about diverting food waste from landfill

Demonstrate -
The use of the technology to a wide audienceThe use of cutting edge technologyFeasibility for implementation and use of the technology
![Page 14: A Defra programme delivered by WRAP with support from the Carbon Trust](https://reader035.fdocuments.us/reader035/viewer/2022081516/5681321c550346895d987cc5/html5/thumbnails/14.jpg)
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.

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

Success depends on
Right peopleRight technologyRight placeAbility to fit the timetable
Claire will explain the process in some more detail

Work groups
Opportunity to networkDevise theoretical projectsFind synergies within the work groups
Projects must meet as many aims as possibleDevise the ideal!Identify barriers, costs, and then solutions and benefits.
