Supermarket operator Sainsbury’s has partnered with food waste recycler ReFood to generate 10% of the supermarket chain’s gas consumption from its waste food.
Announced on 5 May, the scheme sees food waste collected from Sainsbury’s’ two depots in Sherburn-in-Elmet and Haydock, before being converted into gas, heat and fertiliser at ReFood’s anaerobic digestion (AD) processing facilities. The green gas is then exported to the national gas grid by ReFood and, through a third party, is imported by Sainsbury’s stores nationwide. It is used to generate carbon-neutral electricity for power and heating. ReFood has supplied the retailer with almost 50mn KWh of biomethane gas to date.
Paul Densham, utilities buyer at Sainsbury’s, said: “Increasing the sustainability of our UK stores is a key corporate priority and we’re making great progress in our drive to reduce food waste across the business. Working in partnership with ReFood allows us to effectively recycle our food waste while creating green gas.”
