Firefly specialises in a process which converts sewage sludge, a low-value waste product available in large quantities, into SAF.

More than 57 million tonnes of sewage sludge are produced in the UK each year, with the potential to produce 250,000 tonnes of SAF.

Firefly’s SAF, which will be independently certified against the sustainability standard RSB, is projected to deliver a 90% reduction in greenhouse gas emissions compared to fossil jet fuel on a life cycle basis.
