Circularity Fuels Seed

Redwood City-based Circularity Fuels has raised $7 million in seed funding led by Trucks and DCVC, with participation from Sum Ventures and Automotive Ventures. The round follows the company's achievement of completing the world's first end-to-end conversion of raw dairy manure biogas into sustainable aviation fuel (SAF). Circularity will deploy the capital toward an 18-month push to build and operate a demonstration plant, scaling its technology from a lab proof-of-concept into a commercial blueprint for biogas-derived jet fuel.
