The steel industry is responsible for about 4% to 7% of global CO2 emissions and is facing significant pressure to decarbonize. The progress towards carbon neutrality will require an increase in scrap-based electric arc furnaces and a secure supply of high-quality feedstock. End of life steel scrap is often contaminated by tramp elements (e.g., Cu) that originate from copper wires and motors in automobiles, appliances & machinery and can lead to defects in the final steel product. The sector is challenged by opposing trends in the demand for low quality, copper tolerant end products (e.g., construction) and high quality, low copper automotive steels and the constraint of increasing copper contamination of scrap.
By 2025-2030, steel manufactures will need to implement solutions to manage these constraints. We are looking for a solution that can economically upgrade end of life steel scrap to a high-quality feedstock with <0.06wt% copper content.
