Cement industry is one of the highest contributor in carbon dioxide (CO2) emissions. With that, this paper proposes the development of a systematic optimization model where minimized production cost is anticipated within the CO2 reduction target and fuels mixture. The optimization models consider co-processing measures which replaces parts of carbon rich fuels with lower carbon fuels in order to achieve lower carbon emissions. The proposed models are executed using General Algebraic Modeling System (GAMS). With highest carbon reduction of 3.2%, the minimum manufacturing cost went from €59.748/t clinker for a 0% carbon reduction target to €65.737/t clinker.
