Curaclimate provides an electrochemical decarbonization system that captures CO₂ at the source of limestone calcination, enabling up to 85% reduction of process emissions in cement production. The low‑voltage CURALYTE™ platform generates acid and base to leach limestone and precipitate lime, allowing retrofitting into existing plants without altering the standard Ordinary Portland Cement product or requiring major equipment changes.

Problem
Cement production generates about 8% of global CO₂ emissions, primarily from the calcination of limestone, making it a major source of industrial greenhouse gases. Existing decarbonization approaches focus on fuel switching or efficiency gains, which do not address these inherent process emissions. Cement manufacturers lack a retrofit‑ready technology that can substantially cut emissions without replacing plants or altering the standard Ordinary Portland Cement product.
Solution
Curaclimate offers an electrochemical decarbonization system that captures CO₂ at the source of limestone calcination, before the material enters the kiln. The technology uses a low‑voltage electrolyte platform (CURALYTE™) to split water into acid and base; the acid leaches limestone, releasing pure CO₂ for capture, while the base produces calcium ions that are recombined into hydrated lime for use in ordinary cement production. This upstream intervention reduces process‑related emissions by up to 85% while preserving existing plant configurations, material performance, and the supply chain for Ordinary Portland Cement. The system is designed for retrofit integration, requiring minimal additional energy and no major redesign of plant infrastructure, enabling rapid deployment across existing cement facilities.
Target Audience
Primary customers are cement producers and lime manufacturers seeking to meet regulatory decarbonization targets while maintaining existing production lines and product standards.
