London Sainsbury's plans to power its stores using electricity generated from thousands of tons of food waste, Retail Week reported. The British chain will convert the waste into methane gas, which will then provide heat and light for the supermarkets. Sainsbury's wants to become the first British retailer not to send any waste to landfill sites, according to the report.
