Red mud is a toxic by-product of aluminium manufacture, and millions of tonnes of it is produced each year. The majority ends up in landfills, pumped into vast lakes or stored in dried mounds, posing a serious environmental risk. This week, researchers demonstrate how red mud can be reused to make iron, a vital component in the production of steel. As their method uses hydrogen plasma rather than fossil fuels, they suggest it could be a way to reduce the carbon emissions associated with the steelmaking industry.
