Chemical testing of post-process ashes from municipal waste combustion

Abstract

The results of the study presented in the paper are a part of the research project about possibility of utilization of fly ashes obtained from municipal waste combustion in production of cement binders. The main goal was to determine possibility reduction of Cl- and SO42- contents in ashes by leaching. The scope of the examination included SEM observations along with an EDS analysis of chemical composition. Preliminary results show that the major problem is the presence of heavy metals such as Cr, Ni, Cu etc.
