Co Reactive
Co Reactive produces CO‑SCM, a carbon‑negative Supplementary Cementitious Material that mineralizes captured CO₂ into stable carbonates within the cement matrix. The material delivers high pozzolanic reactivity for stronger, more durable concrete while acting as a permanent carbon sink, and it can be used in existing cement and concrete production lines without major equipment changes.

Problem
Concrete and cement production generate a large share of global CO₂ emissions, and existing supplementary cementitious materials (SCMs) often provide limited carbon reduction while requiring changes to manufacturing processes.
Solution
Co‑Reactive offers a carbon‑negative Supplementary Cementitious Material (CO‑SCM) that mineralizes captured CO₂ into stable carbonates within the material’s solid matrix. This process permanently binds CO₂, creating a long‑term carbon sink while delivering high pozzolanic reactivity that enhances the strength and durability of cement‑based products. The material can be incorporated into existing cement and concrete production lines without major equipment modifications, enabling manufacturers to lower the carbon footprint of their mixes and meet sustainability regulations and corporate climate targets. By combining carbon sequestration with performance benefits, CO‑SCM provides a cost‑effective pathway toward carbon‑neutral construction.
Target Audience
Primary customers are cement manufacturers, ready‑mix concrete producers, and large‑scale construction firms seeking to reduce embodied carbon while maintaining material performance.
