Assessing the value of concrete and cement as a carbon sink

08 December 2023, Published under Cement News

This week, the Mineral Products Association (MPA) prepared a 112-page report for the UK Department of Energy Security and Net Zero (DESNZ) to ascertain a two-tier recarbonation model that measures the amount of CO2 absorbed from the atmosphere by concrete in the UK. 'Recarbonation' or carbonation describes how concrete and other cement-containing products naturally absorb and permanently store CO 2 during their lifetime, reversing the calcination reaction. While the Intergovernmental Pan...

The science of carbon removal and carbon sinks

21 July 2023, Published under Cement News

This week Brimstone announced that it had achieved third-party certification of its carbon-negative cement that meets the ASTM C150 standard. Low-carbon and green cements are continuously being developed as alternatives to ordinary Portland cement (OPC). Decarbonising the cement and concrete sectors will need such innovation, but the science of carbon removal from cement and concrete and to what extent they can act as carbon sinks is still a debated subject. While carbon capture, utilis...
