Weathering refers to the natural process whereby CO₂ comes into contact with water and alkaline minerals. The chemical reactions that then take place result in stable carbonate minerals that essentially trap the carbon. The enhanced part means that humans step in to make this happen on a faster time scale, and it’s important to note that trapping carbon in carbonate minerals is one of the safest ways we can store the excess CO₂ in the atmosphere. One approach uses the very abundant, naturally reactive mineral olivine, grinding it and letting it react with water. Our mineralisation removals are supplied by greenSand.
