USE OF CARBON-NEUTRAL MATERIALS IN THE ELECTRIC ARC FURNACE
The application of biochar in steel processes has been the subject of a large number of studies for many years, as coal fuels can be used a priori to replace fossil energy carriers in the steel sector. In particular, biochar, or charcoal, is currently used as a reducing agent in blast furnaces (BOF process) but not in Electric Arc Furnace steel mills (which represent all the facilities in the Basque Country), where coke and anthracite are used as a fuel source, slag foaming agent and steel recarburant. There is a high potential to replace it with biochar and hence reduce the carbon footprint of the steel industry. In Europe, the contribution of biochar to the decarbonisation of the steel sector is well known, and recent publications have shown that the use of biomaterials seems to be ready for implementation, although these studies also highlight the need for further research, such as that proposed in ZEROCARBONHEA.
