Firefly Green Fuels, a pioneering developer of sustainable aviation fuel (SAF) derived from biosolids, today announced a significant capital injection from Builders Vision, a team of investors and philanthropists accelerating tomorrow’s most promising solutions across food/agriculture, energy and oceans.
Builders Vision has a track record of delivering key finance to catalyse cutting-edge global-scale carbon mitigation technologies. This funding signals confidence in Firefly’s novel SAF technology as a high impact venture that centres environmental responsibility alongside long-term economic value.
This strategic funding will enable Firefly Green Fuels to accelerate the development and commercialisation of its proprietary technology, which converts biosolids—organic matter recycled from sewage—into drop-in SAF. As global demand for low-carbon aviation solutions intensifies, Firefly’s innovative process offers a scalable pathway to decarbonize the aviation industry while contributing to a circular waste economy.
“We are thrilled to welcome Builders Vision as a key partner in our journey to redefine how the world thinks about waste and fuel,” said James Hygate, CEO of Firefly Green Fuels. “Their 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.”
We see Firefly as part of a new wave of industrial innovation—building real infrastructure to solve real emissions challenges,” said James Lindsay, Director of Investments at Builders Vision. “This pilot is a foundational step in proving a resilient, scalable pathway for low-carbon fuels in aviation. Securing a massive offtake agreement from Wizz Air a strong signal of market demand and sector readiness that encouraged us to invest in technology with a clear path for scale. It’s exactly the kind of early project that can unlock durable climate and economic value. 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.”
With this funding, and the backing of Builders Vision, Firefly plan to continue scaling operations at pace, with a UK-based first of a kind (FOAK) facility expected to be operational by 2028/29. The company also continues to develop global partnerships, with plans to quickly expand into further territories. By creating a new abundance of waste-derived SAF, Firefly are helping to enable a new era of sustainable growth for aviation.
