Sewage sludge quality standards required by Polish cement plants

Please cite as: CHEMIK 2013, 67, 10, 1019?1024

Incineration of sewage sludge in cement kilns is a good alternative to other methods of disposal. The advantages of such a solution are wastefree production, deactivation of heavy metals in the cement, reduction in the formation of gaseous pollutants due to high combustion temperature. Thermal treatment in the cement industry, however,...
