Global cement emissions standards

21/02/· 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 s.
