Carbon-Neutral Concrete: How does Low-Carbon Cement Production work?

Cement production is responsible for about 8 - 10% of global emissions per year. Roughly 60% comes from the fundamental chemistry of the calcination process and 40% comes from energy to drive the process. The only resource we use more than concrete is water. Like steel, concrete is massively important for modern lifestyle, but we rarely ever think about it.

In this video, I’ll breakdown cement demand, production, and climate impact. We'll have a look at technology and players in the low-carbon cement market.

Ecocem produces low-carbon Cements based on ground-granulated blast furnace slag. CarbonBuilt injects CO2 during the concrete mixing process, which spurs a chemical reaction that permanently mineralizes CO2 within the concrete.
