About

Circularity Fuels develops compact, modular reactor technology that converts waste carbon streams, such as raw biogas from dairy manure, into high-value fuels and chemicals. The company's system pairs an electrified Ouro reforming reactor with a compact Aion Fischer-Tropsch synthesis reactor to produce sustainable aviation fuel (SAF) directly at the feedstock source. This technology aims to decarbonize hard-to-abate sectors like aviation and long-haul trucking while creating new revenue streams for dairy farmers.
