Why we invested

Cement and concrete production account for nearly 8% of global CO₂ emissions, making them one of the largest industrial contributors to climate change. Despite growing regulatory and market pressure, most decarbonization efforts remain limited to efficiency gains or partial material substitution, leaving the industry without a truly carbon-negative, scalable alternative.

Co-reactive is redefining this paradigm through CO₂-reactive mineral technology that transforms industrial residues and natural minerals into high-performance, carbon-negative cementitious materials. Its proprietary continuous reactor system captures and mineralizes CO₂ directly during production, converting emissions into stable carbonates while producing binders with cement-like strength and superior durability. This process operates at ambient conditions, eliminating the need for high-temperature kilns and drastically reducing energy consumption.

With a modular and scalable process architecture, Co-reactive enables industrial decarbonization at source, turning waste streams from sectors like steel and mining into valuable construction materials. By combining materials science, process engineering, and circular design, the company delivers a path toward net-negative construction materials, paving the way for a truly sustainable built environment.
