The steel industry accounts for about 14% of CO2 emissions within the industrial sectors that emit large amounts of CO2
domestically. In this article, we suggest the possibility of introducing carbon-neutral renewable energy in steelmaking based on the
results of the first CO2 reduction large trial test in an electric arc furnace using biocoke technology. We made efforts to reduce CO2
by using bio-coke in scrap preheating arc furnaces. In current issues, about 52% of the input energy is lost in arc furnaces, of which
about 36% is lost as waste gas heat. Especially, we challenged for the first time in the world/domestic to use biocoke as a substitute
for coke in electric arc furnaces. It is considered that the reaction heat of biocoke also contributed to scrap preheating. We have used
biocoke in electric arc furnaces and found that coke reduction is possible. It is hoped that biocoke will contribute to the construction
of a carbon-neutral society and the realization of a decarbonized society through the effective use of biocoke in various fields.
