Firefly Green Fuels, a UK pioneer in sustainable aviation fuel (SAF) made from biosolids, has announced a major capital investment from Builders Vision, a mission-driven investment group focused on scalable climate solutions across food, energy, and oceans.

Turning biosolids into jet fuel: a breakthrough in sustainable aviation technology

Known for backing transformative carbon mitigation technologies, Builders Vision’s funding reflects strong confidence in Firefly’s innovative SAF process, which turns sewage-derived organic matter into drop-in aviation fuel. As demand for low-carbon aviation alternatives grows, Firefly’s technology offers a scalable, circular solution to decarbonise air travel.

“This support validates the potential of our technology to disrupt the SAF market and underscores the critical role that innovative financing plays in addressing climate change,” said James Hygate, CEO of Firefly Green Fuels.

Builders Vision’s James Lindsay added, “We see Firefly as part of a new wave of industrial innovation, building real infrastructure to solve real emissions challenges. Securing a massive offtake agreement from Wizz Air was a strong signal of market demand and sector readiness that encouraged us to invest in technology with a clear path for scale.”

The strategic investment will accelerate Firefly’s commercialisation roadmap, with a first-of-a-kind UK facility expected to be operational by 2028/29. The company is also pursuing international partnerships to expand its global footprint.

“Over the past decade, climate infrastructure funds have outperformed traditional energy benchmarks on a risk-adjusted basis, proving that the future of energy is not just cleaner, but stronger,” said Lindsay.

Backed by Builders Vision, Firefly is now well-positioned to scale its technology and create a new abundance of waste-derived SAF, offering the aviation sector a credible path towards net zero.
