Arca specializes in carbon removal technology that focuses on transforming atmospheric CO₂ into stable mineralized forms, primarily through the use of ultramafic rocks rich in magnesium. The company’s core product is a breakthrough technology that accelerates the natural process of mineralization, effectively capturing and locking away CO₂.

This technology is deployed at large mining operations, specifically targeting nickel mines in regions such as Western Australia. By utilizing existing industrial site infrastructures, Arca enhances the carbon removal capacity of these operations, transitioning them into significant carbon sinks. The customer base primarily includes major mining companies looking to improve their sustainability profiles and contribute to the clean energy transition while operating within the framework of indigenous land considerations. Arca generates revenue through strategic partnerships with mining companies and industrial operations that facilitate large-scale carbon removal projects.

The business model typically involves long-term collaborations where Arca provides its proprietary mineralization technology in exchange for financial compensation based on the volume of CO₂ removed or mineralized. These transactions are structured as B2B engagements, with clients ranging from mining firms to industrial material producers. Revenue is generated through project-based agreements, possibly including milestone payments contingent upon certain carbon removal targets being achieved. Specific pricing structures for Arca’s services or any flagship products have not been disclosed publicly.
