Los Angeles County Sanitation Districts (LACSD) is tapping into existing infrastructure at its wastewater treatment plant to be able to process food waste and convert it to renewable power or transportation fuel. Organics will be processed at its Puente Hills materials recovery facility (MRF), where contaminants will be removed, and a slurry will be created, pumped into tanks and shipped to the plant for co-digestion with biosolids. For now, the system can process 165 tpd of source separated food waste and should be able to digest 300 to 550 tpd by 2020 (out of 4,000 tpd of food waste generated in Los Angeles County). The operation is expected to generate up to 1,440 standard cubic feet per minute (SCFM) of biogas by 2020. More >>
