Effect of mitigation technologies on the total cost and carbon dioxide emissions of a cement plant under multi-objective mixed linear programming optimisation
With the increase of industrial activities in past decades, climate change has been a challenge worldwide. The cement industry is considered one of the industries that generate high carbon dioxide (CO2) emissions. With an imminent increase in CO2 emissions due to increased cement demand, this study...

| Summary: | With the increase of industrial activities in past decades, climate change has been a challenge worldwide. The cement industry is considered one of the industries that generate high carbon dioxide (CO2) emissions. With an imminent increase in CO2 emissions due to increased cement demand, this study proposed a systematic model for a cost-optimal cement plant that fulfils carbon limitations without compromising product specifications. This study considered three mitigation methods for cement manufacturing: co-processing, kiln system improvements, and carbon capture. The mixed integer linear programming model was executed in GAMS. From the optimisation model, it was found that a cement plant with co-processing, kiln improvements, and carbon capture managed to reduce more than 90 % CO2 emissions with USD 135.96/tonne clinker. |
