At full production in the SSAB EMEA steel plants in Sweden, around 97 ktonne sludge and dust generated during cleaning of process gases in iron-and steelmaking processes are annually put on landfill or intermediate storage. These by-products contain high levels of iron (Fe) and carbon (C) that potentially could be recovered to replace some of the virgin materials in the blast furnace process.
