announced its Cannock store is to be run on power generated by food waste from its UK stores.Sainsbury’s has partnered with Biffa to generate the new energy at the Cannock outlet.
The supermarket has used Biffa’s advanced anaerobic digestion facilities and a unique power link-up for the new power supply.
The project has helps Sainsbury’s to continue to send zero operational waste to landfill, said the supermarket.
Any food waste considered unsuitable for donations to charity or animal feed is sent to anaerobic digestion at Biffa where it is then converted to energy.
The remaining food waste is collected from Sainsbury’s supermarkets around the UK.
Sainsbury’s delivery vans are used to collect the remaining food waste from supermarkets and bring it to Biffa’s site in Cannock.
It is then converted into bio-methane gas and used to generate electricity.
Electricity for the Cannock supermarket is directly supplied from the Biffa plant with the use of a 1.5km long electricity cable.
The innovation means that Sainsbury’s Cannock store will now come off the National Grid.
Sainsbury’s is the largest retail user of anaerobic digestion in the UK.
