Technology & Products
Key Products
["CO-SCM (Supplementary Cementitious Material): A CO2-negative additive for concrete.","Continuous Carbon Mineralization Reactor: Proprietary hardware for industrial-scale CO2 conversion.","Carbon Sequestration-as-a-Service: Solutions for industrial emitters to mineralize their flue gas on-site."]
Technological Advantage
The technology offers a 'drop-in' solution for existing cement plants, requiring no major infrastructure changes while locking away one-third of the product's weight in CO2 permanently.
Differentiation
Value Proposition
Permanently sequesters up to 330kg of CO2 per ton of material while providing a 'drop-in' replacement for traditional cement components, helping customers reduce carbon taxes (ETS/CBAM) and meet ESG targets.
How They Differentiate
Utilizes a proprietary continuous carbon mineralization process that converts CO2 and industrial waste (like metallurgical slags) into high-performance Supplementary Cementitious Materials (SCM) that serve as a 'drop-in' replacement for traditional cement.
Market & Competition
Target Customers
Cement and concrete manufacturers, industrial CO2 emitters (steel, power plants), and construction firms seeking sustainable building materials.
Industry Verticals
["Construction & Building Materials","Cement Manufacturing","Carbon Capture, Utilization, and Storage (CCUS)","Industrial Waste Management (Metallurgical Slags)"]
Competitors
