Carbon capture and utilisation processes, CCU, are those processes aiming to produce usable products from CO2-based materials. Although there are a large number of CCU alternatives, only a few are able to propose routes for the massive production of marketable CO2 based products with a negative or neutral carbon footprint in the long term. In this work, a conceptual design of a process aimed to produce a cementitious construction material, based on magnesium carbonate trihydrate,...
