Calgren has completed a dairy biogas project that transformed cow manure into pipeline-quality renewable natural gas (RNG), the first of its kind in California. Calgren's anaerobic digester accelerates the natural decomposition of manure collected from four local dairies. The resultant methane is turned into RNG and injected directly into the SoCalGas pipeline. Calgren plans to add eight additional dairy suppliers by the next 20 years, making the facility the biggest in the US. California has about 30 operational dairy RNG projects and 50 under development.
