Abstract: A steel manufacturing method includes the steps of producing direct reduced iron in a direct reduction plant (1) using a syngas (70) resulting from the gasification of solid waste fuels, producing hot metal (22) and a blast furnace top gas (21) in a blast furnace (2) using a hot blast (20), the blast furnace top gas (21) being at least partly (21A) used into the direct reduction plant (1) and producing molten metal and electric furnace gas in an electric furnace (3) using the produced direct reduced iron (12). Associated network of plants.
