Olivine is one of the most promising natural materials in the field of carbon capture. Without any human intervention, olivine can absorb CO2 up to a third of its weight.  This means that for every tonne of olivine, over 300 kilograms of CO2 are removed from the atmosphere. The carbon dioxide captured is locked in mineral form forever.

Olivine is also cheap and abundant. This is because it is one of the most common rock-forming minerals found in the mantle of the Earth. It is present in basalt rocks all over the world. As an active mineral, its CO2 capturing properties have been known for a long time. Different prototypes are currently being developed to accelerate its natural CO2 sinking properties.

CO2 Reacted olivine is the primary ingredient for novel materials such as concrete, paper or polymer.
