UK supermarket chain Sainsbury's is turning food waste into energy under a partnership with ReFood, with the energy generated that way over the past year being enough to meet 10% of its national gas needs for the year.
The retailer touted the achievement yesterday as it said the UK food waste recycler has supplied it with almost 50 million KWh of biomethane gas to date.
The partnership sees food waste collected from Sainsbury's' two depots in Sherburn-in-Elmet and Haydock and converted into gas, heat and fertiliser at ReFood's anaerobic digestion (AD) facilities. ReFood then exports the green gas to the national gas grid. Through a third party the green gas is imported by Sainsbury's stores nationwide and used to generate electricity for power and heating.
