Emissions from cement works are determined both by continuous and discontinuous measuring methods, which are described in corresponding national guidelines and standards. Continuous measurement is primarily used for dust, NOx and SO2, while the remaining parameters relevant pursuant to ambient pollution legislation are usually determined discontinuously by individual measurements. The following descriptions of emissions refer to modern kiln plants based on dry process technology.

Portland Cement Kiln Dust Reprocessing
If all the potassium from cement kiln dust could be reclaimed, potassium imports could be cut by 25 pct. Moreover, the cement content of cement kiln dust is 13 pct of the total 1982 U.S. cement production. Cement kiln dust has been used as a potassium-rich soil supplement to replace agricultural lime.

Alternative Fuels in Cement Manufacturing | IntechOpen
Apart from use in cement plants, in other countries, for example England, dedicated MBM incinerators are used. The feeding rates of MBM in cement kilns vary from country to country, in Spain the limit is 15 percent of the energy needed in the kilns (Conesa et al., 2005). However, the limit in the feed rate of MBM is due to the effects of chlorides.
