Industrial Mineralization is a durable carbon removal pathway that benefits industry, buyers, governments and communities.

Industrial Partners
Improve project economics and valorize industrial byproducts
We partner with heavy industries which produce alkaline waste streams and byproducts, like mining and steel.
Our process generates new revenue through high-value carbon credits.
This delivers many potential co-benefits:
- Geotechnical stabilization
- Mitigation of hazardous waste
- Increased metal recovery
- Marketable byproducts

Carbon Buyers
Remove carbon for over 10,000 years
- CO₂ is mineralized and locked away permanently
- Removals measured directly on site, with MRV based on established science and third-party verification
- Supply anchored in abundant alkaline feedstocks
- Delivery is proven on the ground in operational sites
- Low resource and land footprint

Technology
Accelerating the natural superpower of rocks
Reactions between rocks and CO₂ have helped shape Earth’s climate for billions of years.
Our breakthrough technology accelerates carbon mineralization and increases the capacity of rocks to absorb and store CO₂.
Gigatonnes of suitable rocks are available in industrial byproducts and ores, representing a multibillion-dollar opportunity.

Deployment
Proven on an operational site
In 2025, Arca completed the world’s first and only carbon removal project using mine waste at an active mine operation. The technologies deployed during this highly successful 18-month demonstration project resulted in a 10x increase in mineralization rate above the baseline. We proved that Arca has the skills to partner seamlessly with heavy industry.
