Bottom Ashes From Waste Incineration Characterization: Concentration of Heavy Metals and Environmental Hazard

EXAFS study of copper in waste incineration fly ashes.

Copper species such as CuCO3, Cu(OH)2, CuS and CuO were found in the bag house and EP (electrostatic precipitator) fly ashes of waste incineration processes by X-ray absorption near edge structural (XANES) spectroscopy. A small amount of Cu(I) and metallic Cu was found in the bag house fly ash. The averaged Cu-O bond distance in the fly ashes determined by EXAFS (extended X-ray absorption fine ...

Treatment and Recovery of Heavy Metals from Incinerator Ashes

High levels of potentially leachable toxic metals such as Pb, Cd, and Cr, in the ash residues require consideration of treatment technologies prior to disposal or utilization of the ashes in other applications. Extraction studies revealed information on the leaching characteristics of the ashes and on the ability of the extraction solutions to separate these metals from the ash matrix. The kine...

LCA of metal recovery from waste incineration bottom ash

The important role gained by waste incineration in European waste management systems is recently clashing with increasing concerns about loss of resources in waste, i.e. metals. Even though the recovery of valuable resources in residues from waste incineration is becoming a widespread practice, a significant portions of valuables resources remains in the ash and ends up in disposal sites. The g...

Characterization of Bottom Ash, Fly Ash, and Filter Cake Produced from Hazardous Waste Incineration

in this study, the chemical characterization of solid residues, i.e., bottom ash, fly ash, and filter cake, produced from the izmit hazardous and Clinical waste incineration Plant (izAyDAS) was investigated. the izAyDAS is located in the city of kocaeli in turkey and it has been in use since 1997. Several parameters were measured, including AoX, Cl-, CN-, So4 2and selected heavy metals includin...
