Nextchem to provide tech to Altalto to convert UK waste and residues into SAF

September 16, 2025 |

In Italy, Maire announces that Nextchem, through its subsidiary MyRechemical, has been awarded an engineering study contract by Altalto  based on its proprietary NX CircularTM gasification and NX CPOTM technologies for a SAF plant in Immingham, Lincolnshire, United Kingdom.

Altalto (Immingham) is a company set up by Velocys to develop SAF projects in the UK. The plant is expected to be operational in 2030. Initial targets include the production of 30 million liters of SAF per year for the UK market in support of the SAF Mandate. Feedstocks will be sourced from residual municipal solid waste (MSW) and commercial and industrial (C&I) waste, Maire said.

The project has been awarded a grant from the Department for Transport’s Advanced Fuels Fund to progress Basic Engineering Design. The SAF from the plant will be enough to power over 500 flights from London to New York per year, the company added.

NX CircularTM gasification technology allows the plant to convert waste by generating synthesis gas (syngas), which is subsequently transformed to SynCrude through Velocys’ Fischer-Tropsch technology and upgraded to high-quality sustainable fuels.
