Assessing the value of concrete and cement as a carbon sink08 December 2023, Published under Cement NewsThis 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... |
