Industry partners Biffa and Sainsbury’s are celebrating a facility that will allow Sainsbury’s Cannock store to run on power generated solely from the supermarket’s own food waste.

Using Biffa’s advanced anaerobic digestion facilities and a power link up, Sainsbury’s Cannock store will come off the National Grid to be powered using electricity generated using food waste from Sainsbury’s stores across the UK. This project helps to close the loop on food recycling and helps Sainsbury’s to continue to send zero operational waste to landfill.

How it works:

· Sainsbury’s send zero operational waste to landfill.

· All food suitable for human consumption goes to their charity partners

· Any food waste that is unsuitable for charitable donations or animal feed (waste bananas from our Prescott Road store go to Knowsley safari park to feed the animals) is sent to anaerobic digestion at Biffa to be converted to energy

· This remaining food waste is collected from Sainsbury’s supermarkets around the UK using Sainsbury’s delivery lorries. It is returned to Biffa’s AD plant in Cannock.

· The food waste is turned into bio-methane gas, which is then used to generate electricity at the Biffa plant

· Electricity for Sainsbury’s Cannock store is directly supplied to the supermarket via a newly constructed new 1.5km long electricity cable

· The new power supply – built in partnership with Biffa – means the Cannock store will come off the National Grid for day to day electricity consumption

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

Paul Crewe, head of sustainability at Sainsbury’s said: ‘Sainsburys sends absolutely no waste to landfill and we’re always looking for new ways to reuse and recycle. So we’re delighted to be the first business ever to make use of this linkup technology, allowing our Cannock store to be powered entirely by our food waste.’

Jeff Anderson, managing director of Biffa’s I&C division, said: “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 the environment. Biffa has a national network of dedicated food collection vehicles providing services for large and smaller customers.”
