  1. Anaerobic Digestion – a demonstration programme under the Environmental Transformation Fund3rd and 4th September 2008

  2. A Defra programme delivered by WRAP with support from the Carbon Trust

  3. 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 • Total: 16-18 Mt/y • ~ 4 times our body weight/year

  4. 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.

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

  6. Drivers – why AD for the UK? • Climate Change • Renewable energy generation capacity • Waste reduction & recycling • Sustainable farming & diversification • Environmental protection & water management

  7. Anaerobic digestion CO2 + CH4 Biogas Digestion vessel Feedstock materials Manures and slurries Food waste (commercial and domestic) Agricultural Byproducts Sewage sludge Biofertiliser

  8. Sweden Finland Germany Scotland Denmark

  9. Biomethane uses

  10. Sewage treatment Crop Residues Other potential feedstocks Manures and slurries

  11. 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)

  12. Why demonstration projects?

  13. Demonstrate - • The use of the technology to a wide audience • The use of cutting edge technology • Feasibility for implementation and use of the technology

  14. 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.

  15. ETF process • ETF branded capital grant • Delivered by WRAP with support from the Carbon Trust • Open tender invitation • Detailed project requirements and evaluation criteria • Capital projects that deliver against key aims

  16. Aim 1 – Maximising cost effective production of biogas • Optimise: • inputs • digestion and solids reduction • gas production and utilisation

  17. Aim 2 – Maximising environmental benefits from use of anaerobic digestate • Fertiliser value • Sustainable agriculture • Competitive agricultural sector

  18. Aim 3 – Maximising potential of anaerobic digestion to reduce carbon footprint of food supply chain • Closing the loop • Biomethane for transport • Heat use • Refrigerant uses • Green energy

  19. Aim 4 – Maximising opportunity for injection of biomethane into gas grid • Efficient gas production • Gas clean up technology • Grid connection and use

  20. Aim 5 – Maximising potential of anaerobic digestion to reduce carbon footprint of water treatment infrastructure • Build on current resources • Knowledge and technology transfer • Efficient use of existing infrastructure e.g. using new feedstocks for the industry • Carbon benefits

  21. Successful projects will be…. • Those that demonstrate cutting edge technology • Those that deliver strongly against the aims of the programme • Those that are most viable both technologically and economically

  22. Putting the jigsaw together

  23. Maximise environmental protection Biomethane to the grid Closing the loop Maximise gas production Water treatment infrastructure

  24. Success depends on • Right people • Right technology • Right place • Ability to fit the timetable • Claire will explain the process in some more detail

  25. Work groups • Opportunity to network • Devise theoretical projects • Find synergies within the work groups • Projects must meet as many aims as possible • Devise the ideal! • Identify barriers, costs, and then solutions and benefits.
