Novacem

Novacem is developing a new generation of carbon negative cement systems, based on research from the Civil and Environmental Engineering Department at Imperial College London. The annual production of over 2.5 billion tonnes of Portland cement is already responsible for 5% of global CO2 emissions, and cement volumes are expected to double by 2050.

In contrast to ordinary Portland cement, Novacem cement absorbs more CO2 over its life cycle than it emits. Novacem estimates that for every tonne of ordinary Portland cement replaced by Novacem cement, around 0.75 tonne of CO2 could be captured and stored indefinitely in construction products. This will transform the cement industry from a significant emitter to a significant absorber of CO2.
