Using our expertise in biological gas fermentation, we designed a process that allows valuable products to be made from waste gases in the iron and steel industry. Unique naturally occurring biocatalysts capture and convert carbon-rich metallurgical waste gases into ethanol. This ethanol can be used for fuels, including as a feedstock for sustainable aviation fuel and can also be used to produce textiles, packaging, and other everyday products, that would otherwise come from virgin fossil resources.
Gas fermentation technology enables a steel plant to reduce emissions and pollutants at source and embrace a circular carbon economy by locking that waste carbon into new products. An attractive and scalable solution, the first European gas fermentation plant – located at ArcelorMittal Gent steelworks – will be commissioned in 2022.
