Max Planck Institute develops method to make green steel from toxic red mud

Researchers at the Max Planck Institute for Iron Research have developed a method to make green steel out of waste produced during aluminum manufacturing. The waste, known as red mud, is highly toxic and is currently disposed of in large landfills. 

“Our process could simultaneously solve the waste problem of aluminum production and improve the carbon footprint of the steel industry,” says Matic Jovičevič-Klug, lead author of the study and scientist at the Max Planck Institute for Iron Research, in a release.
