Project Overview

Altalto Ltd. has partnered with NEXTCHEM, through its subsidiary MyRechemical, to develop a Sustainable Aviation Fuel (SAF) plant in Immingham, UK. The plant will utilize proprietary NX Circular™ gasification and NX CPO™ technologies to convert waste into fuel, with operations expected to commence by 2030.

Production and Targets

The facility aims to produce 30 million litres of SAF annually, sourced from residual municipal solid waste and commercial and industrial waste. This initiative supports the UK's SAF Mandate, which seeks to increase sustainable fuel supply in aviation.

Technological Approach

The NX Circular™ technology generates synthesis gas from waste, which is then transformed into SynCrude using Velocys’ Fischer-Tropsch technology. The NX CPO™ technology enhances this process through controlled partial oxidation, maximizing yield and minimizing carbon intensity.

Economic and Environmental Impact

The project has received a grant from the Department for Transport’s Advanced Fuels Fund to advance its engineering design. It is expected to reduce greenhouse gas emissions by over 100,000 tonnes of CO₂-equivalent annually and create approximately 100 permanent jobs, with an additional 1,000 direct and 300 indirect jobs during construction.
