NEXTCHEM will provide its technologies to Altalto to convert UK waste and residues into Sustainable Aviation Fuel (SAF)
MAIRE announces that NEXTCHEM, through its subsidiary MyRechemical, key player in the Waste-to-Chemical segment, has been awarded an engineering study contract by Altalto Ltd. based on its proprietary NX Circular gasification and NX CPO technologies for a SAF plant in Immingham, Lincolnshire, United Kingdom.
Altalto (Immingham) Ltd. 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 litres (23 thousand tonnes) 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.
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.
Cutting-edge NX Circular 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. The application of this solution, combined with NX CPO™ technology, offers a unique and efficient design. NX CPOTM ensures an advanced innovative process to produce synthesis gas via controlled partial oxidation through a very fast reaction. When applied to synthetic fuel production, this versatile technology is contributing to maximizing overall yield while minimizing carbon intensity of the product.
MyRechemical will operate as a technology provider and as coordinator for other technological partners. It will also supply engineering services supported by NEXTCHEM’s NX Engineering District in Catania and involve other sister companies of the MAIRE Group.
Fabio Fritelli, Managing Director of NEXTCHEM, commented: “This award confirms the validity and flexibility of our technological proposal, which meets the needs of players in the mobility sector, particularly in aviation where decarbonisation is of paramount importance.”
