Circularity Fuels has raised $7.0M in seed funding to turn agricultural biogas into sustainable aviation fuel. Trucks Venture Capital, DCVC, SUM Ventures and Automotive Ventures participated in the round.
The company, founded by former U.S. Air Force Petroleum Office Deployed Lab Chief Dr. Stephen Beaton, emerged from DCVC's entrepreneur-in-residence program. Its proprietary Ouro Reactor, built on modified automotive catalytic converter technology, performs methane reforming at a fraction of the cost and scale of traditional industrial equipment.
