Environmental impacts. the main environmental issues associated with cement production are consumption of raw materials and energy use as well as emissions to air. waste water discharge is usually limited to surface run off and cooling water only and causes no substantial contribution to water pollution. the storage and handling of fuels is a potential source of contamination of soil and impact crusher.

Cement kilns, with their high flame temperatures, are sometimes used to burn waste oils, solvents, and other organic wastes. these practices can result in the release of toxic metals and organics. cement plants are not normally designed to burn wastes; but if such burning is contemplated, the technical and environmental acceptability need to be.
