Rio Tinto to invest $143M to develop R&D facility in Western Australia

The company states: “Rio Tinto will invest $143 million to develop a research and development facility in Western Australia to further assess the effectiveness of its low-carbon ironmaking process, BioIronTM, to support decarbonising the global steel value chain. The development of the BioIron Research and Development Facility in the Rockingham Strategic Industrial Area, south of Perth, follows successful trials of the innovative ironmaking process in a small-scale pilot plant in Germany. BioIron uses raw biomass and microwave energy instead of coal to convert Pilbara iron ore to metallic iron in the steelmaking process. When combined with the use of renewable energy and carbon-circulation by fast-growing biomass, BioIron has the potential to reduce carbon emissions by up to 95% compared with the current blast furnace method. The BioIron facility will include a pilot plant that will be ten times bigger than its predecessor in Germany. It will also be the first time the innovative steelmaking process has been tested at a semi-industrial scale, capable of producing one tonne of direct reduced iron per hour. It will provide the required data to assess further scaling of the technology to a larger demonstration plant.”
