Supermarket Sainsbury’s has revealed that ten of its stores are being powered by energy generated from food waste.
Waste food is collected from two Sainsbury’s depots before being converted into gas, heat and fertiliser at ReFood’s anaerobic digestion facilities.

It is then exported to the national gas grid before being imported by Sainsbury’s into its stores. Here it is converted to electricity for power and heating.
Sainsbury’s utilities buyer Paul Densham 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.”
