About Aemetis

An integrated approach to advanced renewable fuels.

Founded in 2006 in Cupertino, California, Aemetis is an advanced renewable fuels and biochemicals company that commercializes innovative technologies to replace traditional fossil fuels.

Our Mission

Replace high carbon intensity petroleum products with “Below Zero” renewable fuels and byproducts to reverse Climate Change caused by greenhouse gases warming our planet.

Strategy​

Lead the renewable fuels industry transition to Below Zero Carbon Intensity inputs from non-food, low cost agricultural and forest waste sources to maximize California Low Carbon Fuel Standard (LCFS), US Renewable Fuel Standard (RFS), and IRS 45Q credit values.​

One Prudent Wisdom

The Aemetis name is derived from the Scottish “Ae,” meaning “one,” and the Greek “Metis” who was the mother of the goddess Athena, meaning “prudent wisdom.”

“One Prudent Wisdom,” refers to the prudence and wisdom of replacing petroleum with renewable fuels.

Aemetis Leadership

Our Facilities

Our integrated systems allow us to reduce carbon emissions within the transportation ecosystem, create carbon negative circular bio-economies, and create energy that reduces greenhouse gas emissions through the production of sustainable below zero transportation fuels.

Our integrated approach to advanced biofuels includes transporting animal feed byproducts to our partnered dairy digesters, who capture harmful methane emissions from animal waste; using this animal waste to produce renewable natural gas that fuels our refinery and displaces petroleum gas in the pipeline for trucks and other uses; or build advanced fuel facilities to create the lowest carbon intensity sustainable aviation fuels by sequestering CO2 underground.

We own and operate production facilities with more than 110 million gallons per year of production capacity in the US and India. Our production portfolio includes the largest low-carbon ethanol plant in California, a 65 million gallon per year fuel ethanol plant located in Keyes, California near Modesto and renewable natural gas production from surrounding dairy farms. We are expanding our production of low carbon fuels with sustainable aviation fuel and renewable diesel production facilities that use our corn oil, biogas, and local wood waste to produce below zero carbon intensity renewable fuels.
