SisAl Pilot is a 4 year project funded by Horizon 2020 (GA 869268) and it aims to demonstrate a patented novel industrial process to produce silicon (Si, a critical raw material), enabling a shift from today’s carbothermic Submerged Arc Furnace (SAF) process to a far more environmentally and economically sustainable alternative: an aluminothermic reduction of quartz in slag that utilizes secondary raw materials such as aluminium (Al) EoL scrap and dross, as replacements for carbon reductants used today.
