Project: Indirect Carbonation of Alkaline Waste (Kleinman Center for Energy Policy)
"Connected to mine remediation, lab researchers are exploring chemistry that could support the process of reverse mining, or backfilling mines with mine waste infused with CO2. This process would clean the atmosphere while offering mine owners a more valuable product—a qualified carbon offset. An additional health benefit occurs with mine waste composed of asbestos. Reacting CO2 with asbestos alters it from a fibrous mineral (that can be inhaled) into a more benign form."
