Waitrose Supermarket Chain Is In The Avant Garde Of Food Waste Handling

British supermarket chain Waitrose has been a pioneer in preventing and repurposing food waste. Five years ago it stopped sending waste to landfills. Surplus food that can’t be donated to charities is used to generate electricity. And it sells wonky (misshapen or ugly) produce at a discount. The chain has taken the program another step forward: its new fleet of delivery trucks runs on fuel made from food leftovers. The company’s ten eco-friendly trucks can travel 500 miles on the food-waste fuel, which is cheaper than diesel and emits about 70 percent less carbon dioxide. Waitrose chose waste-based gas after researching biodiesel (too expensive) and electricity (batteries too heavy, recharge time too long)
