Abstract: The cement industry is a significant source of CO2 emissions. The implementation of carbon capture, utilisation, and storage (CCUS) technology is one measure aimed at limiting these emissions. This study analyses the mineral carbonation process using CO2 and flue gas as the last stage of the CCUS process applied to cement kiln dust. Moreover, this study provides directions for utilising the products of the process. The results suggest that mineral sequestration using the cement kiln dust can reduce CO2 emissions by 0.42 % at a plant at a cost of EUR 80 per European Union Allowance; this approach can save approximately 41,000 EUR/year. Mineral carbonation can be used as a form of recovery, because the waste products from cement plants can be used in the implementation of CCUS technology, rendering them economically viable.
