In the »BeWiSer« project, a team from Fraunhofer UMSICHT is investigating the potential of biogenic raw and residual materials in steel production as a substitute for fossil carbon and energy sources. Dr. Robert Daschner, head of the Advanced Carbon Conversion Technologies department at UMSICHT, explains: »We want to further reduce residual emissions in a future hydrogen-based steel mill process by using biogenic waste. The project focuses on the production and use of biochar instead of fossil coal and the use of synthesis gas, in particular hydrogen and carbon monoxide.« The co-utilization of plastic-containing residual material fractions, which usually occur within the steel mill process chain, is also being considered. At the end of the project, the planning of a pilot plant for the utilization of biomass with biochar production at the Salzgitter steelworks site should be completed. The technological basis for the plant design is the thermo-catalytic reforming (TCR) process developed by Fraunhofer UMSICHT.
