is the most-used manmade material on the planet. Cement, concrete's binding agent, is made by heating limestone to over 1400°C, causing a calcination reaction that directly releases CO2 into the air. Although it usually makes up only 15% of a conventional concrete mix, cement is responsible for over 95% of concrete's associated emissions-- nearly 8% of all global emissions each year.
Climate Earth, an industry leader in quantifying concrete's data, recently published an article about the environmental impact of cement-based concrete: "Cement acts as the binding agent in concrete, but it is also responsible for the majority of associated with the material. As a result, when people talk about the of concrete, they are largely talking about the carbon footprint of —and how that impact propagates through every cubic meter produced."
CarbiCrete is revolutionizing the concrete industry by enabling concrete production with zero cement. Our innovative replaces 100% of cement in the concrete mix with steel slag, a byproduct of the industry. We then use carbon dioxide to cure the products, trapping in the concrete permanently.
In 2024, CarbiCrete worked with Climate Earth to develop our own Environmental Product Declaration ( ) showing that concrete made with our process has 20X lower emissions than cement-based concrete. That has a major impact on a project's carbon.
