Scientists Are Exploring Ways to Use Asbestos Mineral Waste from Mines to Pull Huge Amounts of Carbon Dioxide from the Air

Washington, DC – The vast surface area of certain types of fibrous asbestos, a class of carcinogenic compounds once heavily used in heat-resistant building materials, makes them particularly good at grabbing hold of the carbon dioxide molecules dissolved in rainwater or floating through the air. The initial hope is to offset the ample carbon emissions from mining itself using these minerals already extracted in the process. But the real hope is that this early work allows them to figure out how to effectively and affordably dig up minerals, potentially including asbestos, specifically for the purpose of drawing down vast amounts of greenhouse gas from the atmosphere.
