Cement-free concrete block promises 73% carbon saving

CCP’s figures suggest that, for an average three-bedroom house, OPC accounts for almost 3.7 tonnes of CO2. In comparison, Greenbloc accounts for 981kg of CO2 for the same house, achieved through a saving of 1kg of CO2 per block and adding up to a total saving of 2.7 tonnes of CO2 per house.

Michael Roddy, managing director at CCP, said: “Greenbloc is a game-changer for the construction industry. Up until now, sustainability has all-too-often been focused on operating carbon emissions post-build, rather than the carbon generated during the build schedule and in the manufacture of building materials. Greenbloc is an important step in the greening of both construction projects and the wider supply chain, as it has the capability to reduce CO2 by up to 73% on a project compared to OPC. In short, the only difference to OPC is that Greenbloc has the ability to dramatically reduce CO2.”
