Rock solid permanence: 10,000 years and longer

Glacier National Park
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.
A unique ability to scale

Arca scientist at a mine tailings facility
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.
A light resource and land footprint

A forest in Western Australia
Industrial mineralization removes and stores CO₂ in one single step, on site, within existing infrastructures.
In short:
- Limited transport: materials are already on site
- Leveraging existing infrastructures
- No additional land required, no separate site for storage
