Aemetis, Inc., headquartered in Cupertino, California, is a renewable fuels and renewable natural gas producer dedicated to decarbonizing the transportation sector. The company operates two primary business segments: Aemetis Advanced Fuels, which manufactures ethanol, biodiesel and sustainable aviation fuel using patented carbon capture and separation technology; and Aemetis RNG, which develops dairy-based renewable natural gas projects in California for pipeline injection and transportation use.
Since its incorporation in 2006, Aemetis has expanded its production footprint through organic growth and strategic acquisitions. The company’s first ethanol plant in Keyes, California, processes locally sourced agricultural feedstocks into low-carbon ethanol. A biodiesel refinery in Riverbank, California produces distilled biodiesel and glycerin, while a majority interest in a facility near Kakinada, India extends Aemetis’s reach into Asian markets, supplying renewable fuels to domestic and export customers.
In collaboration with California dairy farms, Aemetis RNG captures methane from waste lagoons and converts it into pipeline-quality renewable natural gas. These projects generate carbon credits under California’s Low Carbon Fuel Standard by delivering negative-carbon pathways for heavy-duty trucks and other industries. Aemetis’s integrated approach combines feedstock supply, advanced processing technologies and emissions reduction strategies to create low-carbon and carbon-negative fuels.
Led by founder and Chairman & CEO Eric McAfee, Aemetis is focused on scaling its operations across North America and Asia. The company employs long-term offtake agreements, government incentive programs and technology licensing to finance project development. By advancing renewable fuel production and innovative carbon capture solutions, Aemetis aims to meet growing global demand for cleaner transportation energy.
