Ten per cent of Sainsbury’s gas consumption is now being met by energy produced at anaerobic digestion (AD) facilities.
The supermarket chain has a partnership with food waste recycler ReFood which has supplied the retailer with almost 50 million KWh of biomethane gas to date.
Food waste is collected from Sainsbury’s’ two depots in Sherburn-in-Elmet and Haydock and converted into gas, heat and fertiliser by ReFood.
The gas is exported to the national gas grid and, through a third party, is imported by 10 of Sainsbury’s supermarkets nationwide. As well as supplying the gas, ReFood also supports certification.
The partnership helps the retailer’s commitment to send zero operational waste to landfill. All surplus edible food is donated to local charities.
Paul Densham, Sainsbury’s utilities buyer, said: “Increasing the sustainability of our UK stores is a key corporate priority, and we are making great progress in our drive to reduce food waste across the business.
“It sits well alongside our wider sustainability goals, such as working with food redistribution charities and prioritising sustainable transport strategies. The project has helped us to become a market leader in sustainability and waste reduction.”
Philip Simpson, commercial director at ReFood, said: “The partnership has enabled Sainsbury’s to use less fossil fuels, minimise utility bills and eliminate unnecessary food waste disposal.
“With a highly effective sustainable biofertiliser also generated via the AD process, stores nationwide are working together to effectively close the food supply chain – from farm to fork and back again.”
