SIDERWIN - Development of new methodologies for industrial CO2-free steel production by electrowinning
Keywords: steel making, electrowinning, bauxite residue, low CO2 emissions, low energy use, circular economy
SIDERWIN project proposes an environmentally friendly and sustainable electrolytic process that transforms iron oxides into steel plate by electrowinning and has several positive impacts such as:
- a reduction by 87% of the direct CO2 emissions
- a reduction by 31% of the direct energy use
- the ability to produce steel from by-products rich in iron oxides from non-ferrous metallurgy residues
- an increased integration with renewable energies with a more flexible process.
TeSMeT group, steadfast in its goal to address the aluminium industry’s waste problem, examines the application of the SIDERWIN process using a prototype electrolytic cell for the production of Fe metal from Fe2O3 contained in the bauxite residue.
From October 2017 to March 2023.
