A study by Cadent has found that black bag domestic rubbish, agricultural residues, energy crops, sewage and food waste could together generate enough green gas to heat between 7-15mn homes each year. The report, published on Thursday 19 October, found that renewable gas produced from waste and non-waste feedstocks could generate between 68 and 183TWh of biomethane. David Parkin, Cadent’s Director of Network Strategy, said: “The findings of this report show that with the right policies in place renewable gas could play a significant role in helping the UK meet its carbon reduction targets, particularly in heat and transport, which are lagging behind electricity.”
