Concrete4Change is developing novel technology for CO2 mineralisation into concrete, helping concrete manufacturers and the construction industry achieve net-zero.

The innovation underpinning Concrete4Change is to engineer a concrete additive material that acts as a carrier for CO₂. The process can be broken down into four steps as below.

Turning an emission problem into an emission solution

C4C technology is easy to implement, as the carrier can simply be added to the mix along with the other components of the concrete, further reducing cost compared with existing approaches.

The carrier is injected with CO₂ captured from industry, with a particular focus on flue gas generated from cement production – providing a cost-effective route to CO₂ utilisation.

C4C’s technology results in concrete with significantly enhanced strength, reducing the amount of cement required for a given strength of concrete, saving cost, and saving further CO₂ emissions associated with cement manufacturing.
