Novacem is developing a cement that does not use carbonates and can make concrete that absorb carbon dioxide.
The new cement certainly has a vast potential market as the making the 2 billion tonnes of Portland cement used globally every year pumps out 5% of the world’s carbon dioxide emission. A recent report estimated that, by 2020, demand for cement will increase by 50% compared to today.
The new cement reduces carbon emission in the construction industry by replacing the calcium carbonates used in cement formulation with magnesium silicate, and by using a low temperature production process that runs biomass fuels. This new class of cement that offers performance and cost parity with ordinary Portland cement, but with negative carbon footprint.
