Circularity Fuels converts raw dairy biogas to SAF in world first end-to-end pilot
In California, Circularity Fuels announced it has completed what it claims to be the world’s first end-to-end conversion of raw agricultural biogas into sustainable aviation fuel.
Over a six-month pilot run on biogas drawn straight from a California dairy farm’s manure digester, Circularity said it produced drop-in jet fuel meeting ASTM D7566 Annex A1 specifications.
The pilot is the first to convert raw biogas into ASTM D7566 Annex A1 (FT-SPK) jet fuel using a fully integrated, modular system, the firm added.
Circularity Fuels is preparing for its first commercial-scale deployment. The company expects to break ground on its first commercial site in 2027, targeting agricultural biogas resources across the United States, Latin America, and Europe.
