Production of cement and its environmental impact
There are two aspects of cement production that result in emissions of CO 2. The first is the chemical reactions of raw meal in the kiln resulting in the production of the main component of cement, clinker, as carbonates (largely limestone, CaCO 3) are decomposed into CaO and CO 2 by the addition of heat.
