Currently Sainsbury's sends 60,000 tonnes of food waste to landfill sites
A supermarket chain is to use thousands of tonnes of food waste to provide all its stores with electricity.
Sainsbury's is running a pilot scheme across Northamptonshire where food waste is sent for anaerobic digestion near Bedford rather than to landfill.
The process converts waste into methane gas which is then used to generate electricity for Sainsbury stores.
Such is the success of the scheme, by 2009 all of the group's 800 shops will recycle their food waste.
Currently Sainsbury's sends 60,000 tonnes of food waste to landfill sites.
The chain plans to have no food waste going to landfill by summer 2009 and no waste of any kind going to landfill by the end of 2009.
