Food Waste Conversion
Kroger, one of the world’s largest retailers, has taken the lead in converting heaps of food waste into cheap, clean energy for its main distribution center. In lieu of shipping 150 tons of food waste each day from more than 300 Ralphs and Food4Less stores to a composter 100 miles away, the chain installed an anaerobic digestion system to transform organic food that cannot be sold or donated into renewable biogas, which provides power for the 49-acre campus, offsetting more than 20 percent of its energy demand. Combining the use of renewable energy power with more than 150 zero-emission fuel cell forklifts, Kroger has become a beacon for other retailers striving for sustainability. The system was designed and is operated by FEED Resource Recovery, Inc., a clean technology company.
