Novacem Cement Capture Equal Weight Of CO2 To Harden - Carbon Capture Journal
Carbon negative cement from Novacem wins Rushlight Awards
Projects / Policy, Feb 20 2009 (Carbon Capture Journal)
- Novacem, a spin-out from Imperial College, London, won the overall award for its CO2 capturing cement process.
According to Novacem, the annual production of ~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 Portland cement, the Novacem process causes minimal CO2 emissions. It then hardens by absorbing CO2 and so locks atmospheric CO2 into construction materials. This means that for every tonne of Portland cement replaced by Novacem cement, ~1 tonne of CO2 is captured and stored indefinitely. This would transform the cement industry from a significant emitter to a significant absorber of CO2.
