Arca scientists working with eddy covariance towers to measure carbon flux
When CO₂ reacts with alkaline minerals, it forms stable carbonates, locking carbon into rock.
Once mineralized, the carbon is stored in solid form for tens of thousands of years.
Industrial mineralization is one of the most permanent forms of carbon removal available.

Industries such as mining, steel, cement, and legacy power generation produce billions of tonnes of alkaline materials every year. Much of this has the chemistry required for carbon mineralization.
Because this material has already been mined, crushed, and transported, it provides abundant, easily-accessible feedstock for mineralization.
By integrating with existing sites, Arca can leverage the existing infrastructure, process engineering and material flows from heavy industry.
