Wizz Air UK boss visits Firefly facilities to strengthen SAF collaboration

Wizz Air UK’s managing director, Yvonne Moynihan, visited the facilities of Firefly Green Fuels, a key strategic partner in the airline’s journey to net-zero emissions by 2050.
The visit showcases ongoing successful collaboration between the two organisations and underlines commitment to scaling up the use of sustainable aviation fuel (SAF) in the UK.
During the visit, Ms Moynihan met with Firefly’s leadership team, toured the site, and reviewed progress on the development of SAF production capabilities. The discussions focused on the importance of SAF in driving aviation decarbonisation and on the innovative technologies being developed at Firefly to produce SAF from sewage sludge – a low-cost, waste-based feedstock with strong decarbonisation potential.
The site, which is owned by Haltermann Carless, is located with existing infrastructure to upgrade the fuel and strong transport links to London airports.
Firefly is on track to meet their proposed completion date on the first facility in 2029, with additional facilities planned across several other geographies. The Harwich facility will bring new green energy jobs to the area and enjoys strong support from local MPs and residents. The project is expected to contribute to UK energy security while creating a much-needed new disposal pathway for sewage waste.
Wizz Air has signed an offtake agreement with Firefly since 2023, and their partnership will allow the airline to supply up to 525,000 tonnes of SAF over 15 years to its UK operations from 2028.
SAF  is at the heart of Wizz Air’s roadmap to net-zero emissions by 2050, contributing over half of the airline’s planned carbon reductions. Wizz Air is proactively ahead of both EU and UK mandates, having adopted a diversified portfolio approach that includes investment in SAF production, multiple memoranda of understanding, and two long-term offtake agreements – including the partnership with Firefly in the UK.
