Circularity Fuels

Circularity Fuels is on a mission to decarbonize hard-to-abate sectors by turning waste streams into valuable products, starting with converting agricultural biogas into sustainable aviation fuel. Founded by former U.S. Air Force Petroleum Office Deployed Lab Chief Dr. Stephen Beaton, the company emerged from DCVC’s entrepreneur-in-residence program. Its proprietary Ouro Reactor, based on modified automotive catalytic converter technology, achieves methane reforming at a fraction of the cost and scale of traditional industrial equipment. The company has secured $8 million in seed funding and grants from VC firms, the National Science Foundation, California Energy Commission, and others.
