2. Cement Manufacturing Process: The main component of cement is clinker, which is produced from raw materials, such as limestone and clay. [8]. Limestone supplies CaCO 3 for the cement production. Silica, alumina, and iron are considered to be other raw materials. The lime stone used for cement manufacturing contains 75-90 % of CaCo 3

The combustion process in the cement kiln system is an integrated part of the production process, where the fuel-ash becomes part of the cement clinkers and the energy input is consumed to create the hydraulic clinker components. It is therefore not possible to distinguish the process and combustion emissions from one another.

Pre-combustion capture was not evaluated in detail in this study, mainly because it would only be able to capture the fuel-derived CO2, not the larger quantity of CO2 from decomposition of carbonate minerals. Post combustion capture Post combustion capture is a downstream process which would not affect the core of the cement production process.
