The Kroger Co. unveiled anaerobic digestion system to convert food that can’t be sold or donated into biogas that will help power its distribution center in Compton, Calif.
The Cincinnati, Ohio-headquartered retailer expects the system will process more than 55,000 tons yearly of unsold organics and food processing effluent, roughly 150 tons per day. The energy produced will provide 20% of the energy needed by the distribution center, the company said in a news release.
