Renewable Energy: Waste

Volume 490: debated on Monday 30 March 2009

To ask the Secretary of State for Energy and Climate Change if he will make an estimate of the potential contribution of gas produced by community-based anaerobic digesters to the supply of domestic energy. (266260)

The Government have not carried out an analysis based on potential by size of anaerobic digestion plant but rather on technical potential available by feedstock. This initial analysis, published in the Government’s Consultation on a Renewable Energy Strategy, suggests that the anaerobic digestion of food waste, livestock slurries, sewage sludge and energy crops to produce biogas could, technically, contribute approximately 10-20 TWh of heat and power by 2020. This represents up to about 8 per cent. of the renewable energy we estimate will be required by 2020.
