Sainsbury’s powers supermarket by food waste

Sainsbury’s in Cannock will be the UK’s first supermarket to run on electricity generated solely from food waste.

The supermarket giant has partnered with leading waste management firm Biffa to convert food waste from Sainsbury’s stores across the UK into energy, using Biffa’s anaerobic digestion (AD) facilities.

Waste from Sainsbury’s stores is turned into bio-methane gas, which is then used to generate electricity at the Biffa plant, which is also in Cannock.

Electricity for Sainsbury’s Cannock store will then be directly supplied to the supermarket via a new, 1.5km-long electricity cable which will go live on July 21. This new power supply means the Cannock store will come off the national grid for day-to-day electricity consumption.

“Biffa has provided Sainsbury’s with a food collection and processing service for many years. By converting food waste to renewable energy demonstrates our commitment to innovation and the environment,” said Jeff Anderson, managing director of Biffa’s I&C division.

Sainsbury’s is already the UK’s largest retail user of anaerobic digestion, generating enough energy to power 2,500 homes each year.
