The minimill approach, which accounts for 25% of global steel production, comprises of EAF in which recycled steel scrap is melted and then cast into semifinished slab, bloom, or billet forms. The reduction iron/electric arc furnace pathway, which produces around 5% of the world's steel, primarily uses natural gas as an energy reducing agent.
