Rotting leftover food and even sewage are going to be used to produce greener energy to heat Britain’s homes. From the 22nd November homes will be able to use the Ecotricity green gas tariff as a way of cutting greenhouse gas emissions and reducing waste going to landfill. With 18 million tonnes of food waste thrown away each year, Ecotricity say that 700,000 homes could be heated by biogas which in generated in anaerobic digesters from waste food and can be used to produce electricity – or put into the gas network. At the moment homes would still be supplied with traditional gas but Ecotricity plan to move customers onto increasingly green sources, so homes could get their energy from sources that included up to 50% from biogas.

We have to point out that turning food into energy is not perfect – it would be better not to waste food in the first place, it would be better to use excess food on feeding humans and if not humans animals and it is probably better to compost food waste rather that use a biodigester. Still the Food recovery Hierarchy does say that it is better to biodigest than incinerating waste or sending to landfill.[/fusion_builder_column][/fusion_builder_row][/fusion_builder_container]
