Aemetis: Transforming Dairy Farm Methane To Clean Fuel
Aemetis is a leading biofuel provider that harnesses nature-based solutions to provide low-carbon, renewable alternatives to traditional fossil fuels. From its production plant in Keyes, California, the innovative company employs eco-friendly technologies to produce low-carbon ethanol, sustainable aviation fuel and renewable natural gas (RNG).
In 2020, its Biogas division began applying the company’s circular bio-economy philosophy to neighboring dairy farms in California’s Central Valley. With approval by the California Air Resources Board (CARB) and partnership support from Pacific Gas and Electric (PG&E), a biogas pathway was established for the company’s first dairy digesters — transforming the methane released from manure into a commercially viable fuel source. Project goals were mutually beneficial for the state’s environmental initiatives and the local dairy farmers’ operations.
