Impacts of Cement Industry on EnvironmentAn Overview

Pollution control in the cement industry pushes forward this industry to do something about the reduction of the pollutants produced by the manufacturing and handling of cement lime and gypsum. The portland process which accounts for by far the largest part of world cement production is illustrated in figure 1. It comprises two stages clinker manufacture and clinker grinding. The raw materials used for clinker manufacture are calcareous materials such as limestone and argillaceous materials such as clay.

Dust is emitted from storage crushing grinding and pyroprocessing in cement plants. It is the industry s most obvious pollutant since you can actually see it. It can cause respiratory problems. Some of the earliest cement plant emission regulations were for dust. The German Cement Association (VDZ) set up a dust committee as early as the 1930s.

environmental impact due to cement production process in Srilanka. A case study of Puttalam Cement Company Ltd (the only cement production facility that encompasses the entire production process) revealed that the production adopted the dry process which includes supply of raw materials clinker burning and grinding process. Unlike steel the cement industry demands round-the-clock housekeeping with fine dust floating constantly in the air or forming a thin carpet on the floor. This calls for specialised equipment with special features to ensure that air pollution levels are maintained well within the prescribed limits.
