Grocery Chain Turns Food Waste Into Electricity

A New England grocery chain has begun collecting inedible food waste from its stores and processing it into biogas that fuels an electricity generator. The Stop & Shop chain collects and processes 95 tons of waste a day at the plant that opened in April, turning the waste into energy using an anaerobic digestion technology, while keeping it out of landfills. The facility generates 1.14 megawatts of electricity a day, roughly 40 percent of the energy required by the next-door distribution center. The company plans to open more processing facilities in Connecticut.
