3.1 CO2 Cement Production
Carbon dioxide (CO2) is a by-product of a chemical conversion process used in the production of clinker, a component of cement, in which limestone (CaCO3) is converted to lime (CaO). CO2 is also emitted during cement production by fossil fuel combustion and is accounted for elsewhere. However, the CO2 from fossil fuels is accounted for ...
