Sainsbury's has diverted all store waste from landfills, achieving its zero-waste goal in just three years — and seven years ahead of schedule. Putting all waste to positive use and finding ways to reuse it is one of the targets ...Surplus food that can’t be used by the UK supermarket chain’s charity partners is now processed into animal feed to support British farmers or used to generate energy through anaerobic digestion, the company says. All general waste from stores is recycled or turned into fuel. In 1994, Sainsbury’s helped to found FareShare, a UK food redistribution organization. It now provides the charity — and more than 400 local food donation partners — with food fit for human consumption. Sainsbury’s also launched a large-scale food drive, the Million Meal Appeal, to collect non-perishable food and augment its FareShare donations. In 2011 and 2012, after just three days, 3.2 million meals were collected — half donated by customers and half matched by Sainsbury’s. In 2012-13 Sainsbury’s donated more than 10 million meals to food charities across the country including FareShare.
