Firefly
A new route to SAF
Firefly is unlocking a new, homegrown feedstock for SAF, transforming sewage biosolids into a scalable, cost-resilient alternative to fossil fuel.
The future of aviation depends on fuel that works economically – not just environmentally, which is why we take a feedstock-first approach.
Sewage biosolids are a globally abundant waste material that we’re turning into a reliable energy source at scale.
A predictable, scalable supply of SAF
With less exposure to fuel price volatility
A pathway to keeping flight affordable
That delivers an over 90% carbon saving
Our platform makes use of proven hydrothermal liquefaction (HTL) technology to break down wet wastes into bio-crude oil and biochar.
Biochar can be used for carbon sequestration in green construction or in agriculture, where it shows promise as a soil improver.
The bio-crude oil is then upgraded into sustainable aviation fuel (SAF) using proprietary hydrotreatment processes derived from conventional jet fuel production.
