A new Concordia-led study suggests that iron-rich slag, one of mining's biggest waste products, could help store carbon dioxide (CO₂) emissions. The researchers examined whether slag, a waste material generated from metal processing, can trap the greenhouse gas under realistic conditions. While scientists have long known slag can store CO₂ by forming solid minerals, most studies focus on systems that are heavily dependent on water.
