Calculating CO2 process emissions from Cement

2019-12-31  Carbon dioxide (CO2) is emitted from both the chemical process and energy consumption associated with the manufacturing of cement. During calcination or calcining, calcium carbonate (CaCO3) is heated in a cement kiln to form lime, a process that emits CO2 as a byproduct. The resulting lime reacts in the kiln with silica, aluminum, and iron oxides present in the raw material to produce clinker.
