Concrete is everywhere. Our cities are built with it, and it’s the most abundant substance on earth after water. But concrete poses an environmental problem. It is made with cement—the production of which accounts for 5% of the world’s CO2 emissions. The demand for concrete remains high, and with the commitments that both the Canadian and American governments have made to infrastructure spending in the coming years, it will likely increase.
The solution we offer to the industry’s cement problem involves producing concrete in a way that not only eliminates the need for cement, but also captures CO2 — instead of releasing it into the atmosphere.
We’ve developed a process in which cement is replaced as the binding ingredient in concrete with ground steel slag, and where heat-and-steam curing is replaced by curing with carbon dioxide.
