Emission Factors of Cement Industry in Turkey

Abstract

PM, SO2, NO2 and CO emissions were measured by Turkish Cement Manufacturers' Association (TCMA) in cement plants by using standard techniques and equipment since 1997.Emission factors (EF) were calculated by using these availabledata for the cement sector. The emission factors were found bothfor cement and grinding-packing plants separately. The results of the study were compared with international emission factors.It was observed that Turkish Cement Sector's particulate matteremission factors are higher and SO2 emission factors are lower than the values determined for U.S.A., German, Austrian and Dutch cement sectors. When NO2 and CO emission factorsare considered, they are between minimum and maximum values ofinternational emission factors. The results showed that thereis a decrease in dust emissions of Turkish cement plants, especially in the last three years during the period of regular measurements. Also, it was found that more than 90% of air pollution is emitted from primary sources of each plant whichare few in number.
