The construction industry is currently responsible for 38% of global emissions stemming from both operational sources and embodied carbon. In order to curb emissions, there has been a movement towards realigning the built environment with a circular economy framework. Carbon mineralisation within carbonate-based materials has been proposed as the most cost-effective method of CO2 capture and utilisation. This project explores the carbonation of Mg-rich brines into high-purity hydrated magnesium carbonate materials. By controlling the HMC precipitation and post-treatment process, the aim is to impart cementitious properties within carbon negative structures for use in lightweight, fire resistant construction board applications.
