The Los Angeles County Sanitation Districts have developed a food waste recycling program in which food waste is co-digested with sludge at a wastewater treatment plant. Diversion of food waste from landfills is required under California law and reduces greenhouse gas emissions. The Districts program has included initial bench scale lab work, feasibility studies, full scale technology demonstration, commercialization of the program, and energy recovery. The Districts currently receive approximately 300 tons per day of food waste slurry, and have just started up a biogas conditioning system that is generating compressed natural gas to fuel low-emission vehicles. The webinar will provide an overview of the program, a review of how key decisions were made, and the current status of the program.
