Cement-free and carbon-negative

Concrete is the most abundant substance on Earth after water. But a key ingredient in concrete has always been cement, the production of which accounts for 10% of the world’s CO2 emissions. We’re going to change that!

Our process

Our breakthrough technology, which can be implemented in any concrete plant, makes it possible to produce concrete without using cement.

In our concrete, cement is replaced with steel slag—a by-product of the steel-making process that is often placed into landfills.

Using a process called carbonation activation, CO2 is injected into the wet concrete to give it its strength. As a result, any product made using Carbicrete technology permanently sequesters CO2, while turning industrial waste (steel slag) into a high-quality construction product.

Concrete made using this process meets the same specifications as cement-based concrete, has lower material costs, and possesses better mechanical and durability properties.

The end result? A cost-effective process for making precast products that reduces concrete makers’ carbon footprint.

Carbicrete is a finalist in the NRG COSIA Carbon XPRIZE, a $20 Million global competition to develop breakthrough technologies that will convert CO₂ emissions from power plants and industrial facilities into valuable products like building materials, alternative fuels and other items that we use every day.

In the final stage of the competition, Carbicrete will be demonstrating its process at a purpose-built industrial test site at the Alberta Carbon Conversion Technology Centre, a new carbon conversion research hub in Calgary, Alberta.
