## About Firefly Green Fuels

Firefly Green Fuels is a British developer focused on sustainable aviation fuel (SAF).

The company transforms sewage sludge into drop-in jet fuel and biochar fertilizer using a proprietary hydrothermal liquefaction (HTL) process. Firefly is advancing towards commercial SAF production in the UK, with its first facility in Harwich expected to be operational by 2028/29, and plans to expand globally thereafter. The company specializes in the research, development, and commercialization of its sewage-to-SAF fuel pathway. It partners with water and sanitation companies to secure feedstock access and build facilities that convert biosolids into advanced biofuels. Firefly's primary product is sustainable aviation fuel, which can replace conventional jet fuel without requiring modifications to aircraft or infrastructure. Its secondary product, biochar, serves as a fertilizer in agriculture. The company is led by founder and CEO James Hygate OBE, who has extensive experience in the biofuels industry.
