The high level of CO 2 emission happens when burning fossil fuels to generate heat to initiate the cement manufacturing process and thermal decomposition of calcium carbonate in the progression of manufacturing cement clinker. During this process, 30–40% is derived from burning fuels and 60–70% result from decarbonation [4–7].
