Arca is a leading carbon dioxide removal (CDR) company. Arca accelerates 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.

Heirloom is a carbon capture company developing direct air capture technology that accelerates the natural absorption of carbon dioxide. Its approach uses a limestone-based process to increase CO2 uptake and stores the captured carbon permanently underground, powered by renewable energy. The company also applies carbon capture and utilization techniques to enhance natural CO2 removal. By offering a scalable, renewable-energy driven solution, Heirloom aims to help businesses meet sustainability goals with a cost-effective path to significant carbon removal.

Safi Organics is a company focused on enhancing agricultural productivity by supplying high-quality organic fertilizers to rural farmers. Its innovative approach involves the development of carbon-negative fertilizers produced from locally sourced agricultural waste, utilizing proprietary low-cost, decentralized biomass conversion technology. This process not only helps farmers improve their crop yields and income but also addresses environmental concerns by reducing waste and mitigating pollution associated with traditional waste burning practices. Through its sustainable solutions, Safi Organics aims to support the agricultural community while promoting environmentally friendly practices.

Takachar is a company focused on transforming agricultural waste into valuable products, particularly eco-friendly cooking fuel. Operating primarily in Kenya, it has developed low-cost technologies that enable the conversion of unmanaged agricultural residues into charcoal, a non-toxic and affordable energy source for low-income households. Over the past three years, Takachar has established or assisted seven locally run waste-to-charcoal enterprises, some of which have achieved operational profitability. The company has successfully created approximately 100 jobs and sold 50 tons of its eco-char product. By utilizing oxygen-lean torrefaction reactors, Takachar helps farmers reduce waste through recycling, allowing them to generate additional income while preventing open burning of agricultural residues. The company aims to demonstrate the financial sustainability of these enterprises as a foundation for expanding its franchise network in the future.

Project Hajar is an integrated direct air capture and mineralization (DACM) project by MZT and 44.01, situated in Oman.
