Environmental Guidelines for Cement Manufacturing

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

Bigger Climate Action Emerging in Cement Industry UNFCCC

The cement manufacturing process is resource and energy intensive due to the extreme heat required for production. For example large amounts of fossil fuels are used to heat a high temperature kiln to around 1400 C and decompose limestone and other raw materials to form a substance called clinker which is then combined with gypsum to make .

DOC Environmental impact of precast construction
