Launched in September 2019, the EU-funded project AlSiCal aimed to make the mineral and metal industry more sustainable and environmentally sound. The project researched, developed and de-risked a ground-breaking new technology for alumina production. Integrating carbon capture enabled the co-production of three essential raw materials (alumina, silica, and precipitated calcium carbonate) using new resources – e.g., anorthosite, abundantly available worldwide – without generating bauxite residue and CO2 emissions. The project consortium spanned 9 European countries and involved 16 partners. It ran until February 2024.
