Partnership with NEXTCHEM integrates breakthrough NX Circular gasification and Velocys’ proven Fischer-Tropsch technology
Houston and Oxford, England – September 8, 2025 – Altalto (Immingham) Limited, owned by Velocys, has been awarded funding from the UK Department for Transport’s Advanced Fuels Fund to complete Basic Engineering Design for its flagship waste-to-SAF facility. The grant enables Altalto to integrate NX Circular™ gasification and NX CPO™ technology from NEXTCHEM with Velocys’ proven MicroFTL™ technology, strengthening its position as the most advanced municipal solid waste-to-SAF project in the UK—and globally.
Altalto is designed to produce 30 million litres (23kT) of sustainable aviation fuel annually from residual waste streams, enough to power over 500 London–New York flights per year. Once operational, the project will deliver more than 100,000 tonnes of CO₂-equivalent savings annually, support the circular economy by diverting waste from landfill and incineration, and create hundreds of jobs in the Humber region.
The project now has planning consent, strong government support, and selected technology partners across the full value chain, including waste sourcing, gasification, Fischer–Tropsch synthesis, and fuel upgrading. With Front-End Engineering Design (FEED) expected to commence in early 2026, Altalto is positioned as the UK’s near-term commercial-scale SAF solution.
Matthew Viergutz, CEO of Velocys, said:
“This new award underscores the UK Government’s confidence in Altalto and in Velocys’ Fischer–Tropsch technology. By integrating NEXTCHEM’s proven gasification systems, we are strengthening Altalto’s pathway to becoming the UK’s first commercial waste-to-SAF plant. Altalto is alive, advancing, and represents the most near-term opportunity to deliver meaningful volumes of sustainable aviation fuel from waste.”
With the UK’s SAF Mandate requiring 10% of jet fuel demand to be met by sustainable sources by 2030, Altalto stands ready to anchor the nation’s pathway to net-zero aviation.
