Circularity Fuels converts biogas into sustainable aviation fuel.

0% Fossil. 100% Compatible.

Our proprietary reactors combine the methane and carbon dioxide components of biogas into syngas 100x cheaper than gas-fired reactors. We then convert the syngas into sustainable aviation fuel via Fischer-Tropsch.

Biogas to SAF with Proven Technologies

Biogas production has exponentially increased over the past decade, and our technology provides another valuable product for biogas developers. Best part: our biogas to SAF architecture is based on our commercially demonstrated technology that converts other carbon-rich streams into valuable hydrocarbons.
