Southern California Gas Co. and biogas producer Calgren Dairy Fuels today announced that renewable natural gas produced with biogas upgrading equipment from ABC member DMT at Calgren’s dairy digester facility in Pixley, California is being injected into SoCalGas pipelines. The project marks the first time that carbon-negative renewable natural gas produced from cow manure has been injected directly into SoCalGas’ natural gas system. In August 2018, SoCalGas began receiving renewable natural gas into its system from ABC member CR&R, Inc.’s anaerobic digestion facility in Perris, California. The renewable natural gas from that digestion facility is already being used to fuel about 400 waste hauling trucks. More>>
