Arca is a leading Carbon Dioxide Removal (CDR) company. Arca accelerates the natural process of carbon mineralization by reacting atmospheric carbon dioxide with ultramafic mine tailings rich in magnesium silicate minerals, such as serpentine and brucite. By leveraging partnerships with mining companies, Arca transforms mine waste into a carbon sink, permanently storing CO₂ as stable carbonate minerals. The company is at the forefront of scaling Carbon Dioxide Removal (CDR) solutions by integrating geochemical expertise, real-time monitoring, and verification methodologies. Arca collaborates with major buyers of carbon removal credits, such as Shopify, Stripe, Watershed, and MaRS, and has established formal methodologies for recognizing and quantifying mineralization in voluntary and compliance carbon markets.
