In the context of the decarbonisation of the building sector, this work focuses on the process economics of a carbon capture and utilization alternative for the production of a novel construction material based on magnesium carbonate trihydrate, also known as nesquehonite. This material, after a dehydration-rehydration process, can be conformed into moulds with a significant compressive strength in a very similar mechanism to plasterboard manufacturing. This paper discloses the mass and energy balance of the...
