SO2 emissions from cement plants are primarily determined by the content of the volatile sulphur in the raw materials. Kilns that use raw materials with little or no volatile sulphur have SO2 emission levels well below this level without using abatement techniques. The current reported emission range is <103500 mg SO2/m 3.
