Green Cement Production: Potentials and Achievements

Abstract

Abstract — In this work, three strategies of CO2 reduction including energy saving, carbon separation, and storage as well as utilizing alternative materials in detail have been reviewed. In case of energy saving approaches, shifting to more efficient process shows the best results since potentially mitigates almost 20% of CO2 emissions in the process. Carbon capture and storage (CCS) is also considered as an effective way to avoid release of CO2. However economical and technical challenges still play as remarkable obstacles against implementing such processes in cement plant. As far as alternative materials are the case, utilizing waste-derived fuel (WDF) and industrial by-products instead of conventional fuels and materials result in significant emission mitigation.
