Climate change mitigation entails reaching net-zero emissions, which in turn requires unprecedented actions in all aspects of society. These include the cement industry, which represents 7% of global CO₂ emissions. A proposed option for reducing CO₂ emissions in the cement industry is the use of CO₂-containing flue gas and cement kiln dust (CKD) for producing mineral carbonates that serve as non-reactive fillers for blending cement. This work proposes the mineral carbonation of CKD (MCCKD process) to convert CO₂ to synthetic carbonates and analyzes under which conditions the MCCKD process can be a promising concept for the cement industry in Colombia. For this purpose, an existing conventional cement plant (base case) is compared with a hypothetical cement plant with MCCKD. Both systems are compared in an integrated techno-economic and environmental assessment and in eight emission …
