Web1.1.1.2 Environmental friendly. World steel production is indirectly dependent on coal. According to the World Coal Association [4], 70% of steel is produced in basic oxygen furnaces, where coking coal is a vital ingredient in this steel-making process. A further 29% of steel is produced in electric arc furnaces.
