Sainsbury's has 28 of it's stores in Scotland leading the way in waste reduction as they begin diverting approximately 42 tons of food waste per week from the landfill to be made into biofuel and electricity.
Sainsbury, has a zero food waste target for their entire chain of stores in the UK.

In making the announcement at the Zero Waste Conference on Jan. 21 in Edinburgh, Scotland, Alison Austin, Sainsbury's environment manager, said each ton diverted from the landfill will generate enough power for 500 homes and save 3 tons of carbon dioxide compared to fossil fuels. "Scotland is at the forefront of our wider U.K. plan to completely cut out dependence on landfill," Austin said. "This is the first step in a plan that will see Sainsbury's stop using landfill for food waste by this summer and stop using landfill completely by the end of the year."

Sainsbury is working with PDM Group, a food waste recycling and rendering company. PDM has a network of biomass combustion plants and a planned network of anaerobic digesters. The first digester at the company’s headquarters in Doncaster, S.Yorks is expected to be operational later this year generating 2 megawatts of renewable energy.
The company collects unsold or unusable food products, such as animal by-products, from most of the U.K.’s major retail chains which are recycled to produce biofuels or generate electricity.
