One Sainsbury's supermarket in Britain will soon begin using unsellable and waste food products for power. Produce that is a little past its prime but still edible will be donated to charities, while food that's even older will be used in the production of animal feed and donated to zoos.
Food that's completely rotten however will be picked up from Sainsbury's supermarkets and stores across the UK by the same trucks that deliver fresh food -- saving on transportation-related emissions.
The trucks will then deliver the food waste to a special plant, where it will be converted into bio-methane gas, which in turn will be used to produce electricity.
This electricity will then be supplied to the Sainsbury's supermarket in the town of Cannock via a cable. This electricity will meet the store's day-to-day needs and allow it to operate independent of the national electricity grid.
