Arca Climate
Arca develops technology to accelerate industrial mineralization, capturing atmospheric CO2 by reacting it with alkaline industrial waste materials. This process transforms waste streams into stable carbonate minerals, providing permanent carbon removal at gigatonne scale. The company operates within existing industrial sites to achieve climate impact with a minimal physical footprint.

Problem
The concentration of atmospheric carbon dioxide is a primary driver of climate change, necessitating scalable and permanent carbon removal solutions. Natural carbon mineralization, while effective, is a slow process, limiting its potential to address the urgency of climate change.
Solution
Arca Climate accelerates the natural process of carbon mineralization to permanently remove atmospheric CO₂. The company's technology enhances the reaction between ultramafic rock and CO₂, transforming mine tailings into valuable carbon sinks. By partnering with critical metal mines, Arca Climate leverages existing industrial sites to achieve gigatonne-scale carbon removal with a reduced environmental footprint. The company's autonomous rovers and scientific team work to speed up the mineralization process and measure real-time carbon removal data.
Target Audience
Arca Climate's primary customers are critical metal mining companies seeking to transform their operations into carbon sinks, as well as organizations looking to invest in large-scale carbon removal projects.
Features
- Accelerates carbon mineralization using ultramafic rock.
- Deploys autonomous rovers to enhance the mineralization process at mine sites.
- Measures real-time carbon removal data.
- Partners with critical metal mines to leverage existing infrastructure.
