Anaerobic Digestion – a demonstration programme under the Environmental Transformation Fund 3 rd and 4 th September 2008

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

 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: Mt/y ~ 4 times our body weight/year Food waste the hidden resource?

 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

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 slurries Food waste (commercial and domestic) Agricultural Byproducts Sewage sludge CO 2 + CH 4 Anaerobic digestion

Biomethane uses

Other potential feedstocks Manures and slurries Crop Residues Sewage treatment

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)

Why demonstration projects?

Demonstrate - The use of the technology to a wide audience The use of cutting edge technology Feasibility 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 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

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

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

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

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 infrastructure  Build on current resources  Knowledge and technology transfer  Efficient use of existing infrastructure e.g. using new feedstocks for the industry  Carbon benefits

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

Putting the jigsaw together

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

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

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.
