Turn CO 2 into Value

Co-reactive is on a mission to turn CO2 into value by pioneering a breakthrough carbon mineralization technology that transforms CO2 into high-performance Supplementary Cementitious Materials (SCM) to enhance the strength and durability of cement-based construction materials, driving carbon neutrality of high-volume construction sector.

We strive for a world in which construction is carbon neutral through carbon negative materials.

CO‑SCM is a high‑performance, carbon‑negative Supplementary Cementitious Material (SCM) specifically engineered to maximize pozzolanic reactivity and improve cementitious properties. Unlike conventional SCMs, CO‑SCM permanently binds CO₂ by mineralizing it into stable carbonates within the solid matrix, thereby acting as a long‑term carbon sink. At the same time, the material enables high strength and durability, making it a strong solution for low‑carbon construction.

CO-SCM seamlessly integrates into a wide range of cement and concrete applications, offering superior performance, sustainability, and cost benefits across multiple industries.

A Carbon-Negative (carbon-storing) Supplementary Cementitious Material (SCM) for Sustainable Construction

We understand that sustainability matters—but so does performance and cost. CO-SCM is designed to provide all three.

Lower carbon footprint without changes to existing production processes

High strength and durability enabled by a significant amorphous silica content

Alignment with sustainability regulations and corporate climate targets

Cost-efficient material economics, enabling competitive pricing in a rapidly evolving market

• Drastically reduce CO₂ costs & certificates (ETS, CBAM)
• Meet ESG criteria & increase market attractiveness
• Unlock long-term economic value through green building materials
• Complement traditional SCMs without disrupting existing formulations

• Technically validated and certified materials
• Compliance with relevant norms and standards
• Collaboration with leading industry partners
• Locally sourced, sustainably available raw materials

Feedstock preparation Carbon Sourcing Reactor Separation Green substitute material

Our journey begins with selecting the perfect feedstock materials. We use magnesium and calcium silicate minerals, like olivine, which are abundant and already mined itionally, we upcycle secondary minerals from metallurgical processes, giving them a new life through our proprietary carbon mineralization process. These materials are finely milled into a powder, ready to undergo carbonation.

The required CO₂ for our process can come from various CO₂ sources, such as cement plants, power generation, waste combustion, biogas plants, Direct Air Capture, or pipelines. We can set up our site directly next to source point emissions to minimize the costs of CO₂ transportation.

The powder is then suspended in water before it enters our tubular reactor system. The reactor operates under high pressure and temperature to accelerate the transformation of the feedstock powder into rock-solid carbonates and amorphous silica. At the exit of the reactor, the feedstock is completely transformed into high-performance CO-SCM.

After the liquid suspension has passed the reactor the newly formed CO-SCM material is separated from the water using a filter press. In a rotary dryer the residual moisture evaporates and the CO-SCM exits as a fine powder ready to be used.

CO-SCM seamlessly integrates into a wide range of cement and concrete applications, offering superior performance, sustainability, and cost benefits across multiple industries. It can be delivered in big bags or silos.
