Cement manufacture is a source of the following airborne contaminants: particulate matter, nitrogen oxides, sulfur dioxide, carbon monoxide, and carbon dioxide. [3] Cement production releases carbon dioxide by sintering limestone or shells. It is also very energy-intensive, with the result that the cement industry is a large emitter of carbon ...
Cement kilns are used for the pyroprocessing stage of manufacture of portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates. Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity ...
