Sustainable Aviation Fuel and Renewable Diesel

We create renewable fuels from renewable agricultural byproducts or waste products.

Aemetis’s sustainable aviation fuel (SAF) and renewable diesel (RD) are created from waste oils/fats and biomass generated from agricultural wastes. Complex technologies work in tandem to transform these various waste resources into higher-value clean fuels.

Aemetis is in the process of developing advanced RD and SAF from oils, fats and tallows available in California. Aemetis is also in the process of developing fuels and energy from woody waste generated with byproducts of agriculture and forest management.

The Aemetis facilities are designed with flexibility in mind, with the ability to adjust the outputs to produce either renewable diesel only or a mix of RD and up to 50% SAF, allowing Aemetis to respond to changing market conditions for the two products.

Aemetis has purchased a 125-acre, commercial/industrial site at a former US Army munitions facility in the Central Valley town of Riverbank that will be the site of the SAF/renewable diesel facilities. It will be co-located with a Carbon Capture and Storage facility, allowing Aemetis to reduce atmospheric carbon levels as part of its SAF/renewable diesel production efforts.

Why SAF and Renewable Diesel?

The U.S. consumes more than 40 billion gallons of diesel on U.S. roadways every year and more than 10 billion gallons of aviation fuel. Petroleum in transportation creates 1,700 Million metric tons of CO2 per year. Diesel and aviation fuel also emit soot, carbon monoxide, nitrogen oxides (NOx), and other hazardous air pollutants.

Renewable diesel meets the same standards and quality controls of traditional petroleum diesel. Renewable diesel performs comparably to traditional diesel but contains dramatically lower tailpipe and lifecycle emissions.

Additionally, our facilities will produce SAF and renewable diesel at or below the carbon intensity of comparable fuels in the market today. When combined with carbon capture and storage, our facilities permanently remove atmospheric carbon dioxide, lowering overall greenhouse gases. Transportation relies heavily on petroleum, and finding nature-based alternatives is one of the most powerful ways to stop greenhouse gas emissions.
