UK supermarket to produce biogas

After signing a contract with Biffa, a UK-based integrated waste management business, Sainsbury’s supermarket looks set to turn all of its food waste into biogas by 2012.

Biffa will use anaerobic digestion (AD) technology to create biogas from the discarded foodstuff, before it is injected into the national grid.

AD is a green and cheap solution of disposing of waste, while extending the life of landfill sites and generating energy at the same time. Already extremely popular in Germany, AD is now one of fastest expanding renewable technologies, with around 1,000 new digesters being built every year.

Neil Sachdev, commercial director of the supermarket chain, said, ‘We are desperate for greater anaerobic digestion capacity and would therefore like to see greater, clearer incentives for investment in this green technology.’
