No food fit for human consumption will be wasted by Tesco's UK stores by the end of February, the retail giant says. Chief executive Dave Lewis told the Daily Telegraph food waste had been "talked about for years" as he unveiled the plans for all 2,654 stores. Urging other chains to follow suit, he said edible food should be used for people, not go to waste. Tesco, with all major UK supermarkets, has signed a commitment to cut food waste by one-fifth within a decade. The voluntary agreement is known as the Courtauld Commitment 2025. Mr Lewis ... said the contrast between the amount of wasted food in the UK and the situation in countries suffering food shortages was "really stark". He said: "Last year we sold 10 million tons [10.2 million tonnes] of food to the British public. But even if our waste is just 0.7% of the food, that's still 70,000 tons [71,100 tonnes] of food. Tesco says it cuts waste by selling surplus groceries with "reduced to clear" stickers and [by using] an app, FoodCloud, to scan and upload surplus food that stores have at the end of the day, which is shared with registered charities that collect the food. "That goes a long way in reducing charities' bill burdens, so they can spend the money on ... providing much more needed services," Mr Lewis said. "Food waste has been talked about for years but if Tesco can make this work, with all of our different stores across the country, then why can't everybody," he added.
