  • Waste Co-processing in Cement Kilns

    Mechanism of Waste Management Through Co-processing In Cement Kiln The organic constituents are completely destroyed due to high temperatures, long residence time and oxidizing conditions in the cement kiln. Acid gases such as HCL and SO 2 are absorbed and neutralized by the freshly formed lime and other alkaline materials within the kiln.
