Circularity Fuels
Circularity Fuels converts waste carbon streams from dairy farms, agricultural plants, and industrial facilities into sustainable aviation fuel using its electrified, AI-controlled Ouro Reactor™ and next-generation Aion Reactor™. The company's reactors run dynamically on solar and wind power, producing drop-in jet fuel compatible with existing aircraft. Its platform also produces lab-grown diamonds, commercially available today.

Problem
The reliance on fossil fuels contributes to climate change and geopolitical instability, necessitating cost-effective alternatives. Existing direct air capture (DAC) methods for converting atmospheric carbon dioxide into hydrocarbon fuels are often prohibitively expensive, and waste gas streams from farms and industrial facilities are typically vented or flared rather than utilized.
Solution
Circularity Fuels cuts the cost of waste-gas-to-SAF reactors, making sustainable aviation fuel finally affordable. The company captures waste carbon streams—biogas from dairy farms, agricultural plants, and industrial facilities—and converts them into clean syngas using its electrified, AI-controlled Ouro Reactor™, which operates 100× cheaper than gas-fired reformers. The Aion Reactor™ then performs next-generation Fischer–Tropsch synthesis to assemble the syngas into a light, already-isomerized liquid fuel mixture, which is separated into drop-in jet fuel compatible with existing aircraft and infrastructure. The reactors run dynamically on solar and wind power when abundant, supporting the grid when not, creating a closed carbon loop from waste source to wing.
Target Audience
Primary customers are airlines and fuel partners seeking affordable sustainable aviation fuel, as well as dairy farms, agricultural plants, and industrial facilities looking to monetize their waste carbon streams.
