The process, known as BioIron™, uses raw biomass instead of metallurgical coal as a reductant and microwave energy to convert Pilbara iron ore to metallic iron in the steelmaking process. BioIron™ has the potential to support near-zero CO 2 steel-making, and can result in net negative emissions if linked with carbon capture and storage.
