meaning that its readymix concrete products are responsibly sourced and customers can score more credits under BREEAM .
A recent tie-up recently saw CEMEX Ventures sign an agreement with Carbon Clean to develop a carbon capture solution for the cement industry that lies below the line of US $ 30 / ton cost of CO2 captured . Could this prove to be the ‘ game changer ’, allowing for the economically viable capture of carbon emissions in the cement industry at an industrial scale ?
Gonzalo Galindo , Head of CEMEX Ventures , said : “ Due to the effect of CO2 emissions on global warming and the importance of implementing new solutions to reduce the environmental impact , we look forward to joining efforts with other companies that are also working towards achieving carbon neutrality .”
University of Sydney researchers recently poured ‘ green cement ’ – pavement made from a unique mix of fly ash , and waste materials including ground glass and gaseous carbon dioxide .
The trial eco-pavement has saved 752kg of sand from being dredged and 327kg of carbon dioxide being emitted into the atmosphere , while its production has saved the equivalent energy of 1,000 cups of coffee or driving a car over 1,800km . Researchers are also testing an algorithmic intelligence technique that adapts the concrete blend to specific applications .
Scientists at London-based Novacem claim to have developed a new form of concrete that effectively absorbs large amounts of carbon dioxide as it hardens . Novacem ’ s new version of concrete , uses a different raw material , magnesium sulphate , which requires much less heating . Novacem claim that each
