“…It should be noted that some of these studies correspond to comprehensive analysis, where diverse properties are also indicated (Le Forestier and Libourel, 1998;Alba et al, 2001;Bodénan and Deniard, 2003;Li et al, 2003aLi et al, , 2004. Additional works may also be referred in the context of characterization of the considered residues (Sawell et al, 1999;van der Sloot et al, 2001;Song et al, 2004;He et al, 2004;Geysen et al, 2006;Quina et al, 2007).

This work reviews strategies for the management of municipal solid waste incineration (MSWI) residues, particularly solid particles collected from flue gases. These tiny particles may be retained by different equipment, with or without additives (lime, activated carbon, etc.), and depending on the different possible combinations, their properties may vary. In industrial plants, the most commonly used equipment for heat recovery and the cleaning of gas emissions are: heat recovery devices (boiler, superheater and economiser); dry, semidry or wet scrubbers; electrostatic precipitators; bag filters; fabric filters, and cyclones. In accordance with the stringent regulations in force in developed countries, these residues are considered hazardous, and therefore must be treated before being disposed of in landfills. Nowadays, research is being conducted into specific applications for these residues in order to prevent landfill practices. There are basically two possible ways of handling these residues: landfill after adequate treatment or recycling as a secondary material. The different types of treatment may be grouped into three categories: separation processes, solidification/stabilization, and thermal methods. These residues generally have limited applications, mainly due to the fact that they tend to contain large quantities of soluble salts (NaCl, KCl, calcium compounds), significant amounts of toxic heavy metals (Pb, Zn, Cr, Cu, Ni, Cd) in forms that may easily leach out, and trace quantities of very toxic organic compounds (dioxin, furans). The most promising materials for recycling this residue are ceramics and glass-ceramic materials.The main purpose of the present paper is to review the published literature in this field. A range of studies have been summarized in a series of tables focusing upon management strategies used in various countries, waste composition, treatment processes and possible applications.

“…Incineration can also destroy pathogenic agents and generate thermal energy that can be reused (Marani et al, 2003;Porteous, 2005). However, the emission of bioavailable HMs during the incineration process is of concern (Belevi and Moench, 2000;Song et al, 2004;Hopes et al, 2003;Renoux et al, 2001). The HMs can be stabilized in the incinerator residues (or slag) (Arickx et al, 2006;Xu et al, 2008), and trapping of the HMs into the slag could reduce emission of the metals and make the incineration process environmentally friendly.…”

“…The solid wastes produced during the incineration of MSW that are more often studied are the bottom ashes [43][44][45][46][47][48], probably due to the several potential practical applications that are possible for this residue. Sometimes the bottom ashes, fly ashes and APC residues are considered in the same study [33][34][35]39,42,[49][50]. In other cases, the characterization is only referred to the particles that are colleted in the electrostatic precipitators (ESP) [41,51], or in the scrubber units and fabric filters or other possible combinations [31,32,[36][37][38]40,[52][53][54][55][56].…”

This study is mainly related with the physical and chemical characterization of a solid waste, produced in a municipal solid waste (MSW) incineration process, which is usually referred as air pollution control (APC) residue. The moisture content, loss on ignition (LOI), particle size distribution, density, porosity, specific surface area and morphology were the physical properties addressed here. At the chemical level, total elemental content (TC), total availability (TA) and the leaching behaviour with compliance tests were determined, as well as the acid neutralization capacity (ANC). The main mineralogical crystalline phases were identified, and the thermal behaviour of the APC residues is also shown. The experimental work involves several techniques such as laser diffraction spectrometry, mercury porosimetry, helium pycnometry, gas adsorption, flame atomic absorption spectrometry (FAAS), ion chromatography, scanning electron microscopy (SEM), X-ray fluorescence (XRF), X-ray diffraction (XRD) and simultaneous thermal analysis (STA). The results point out that the APC residues do not comply with regulations in force at the developed countries, and therefore the waste should be considered hazardous. Among the considered heavy metals, lead, zinc and chromium were identified as the most problematic ones, and their total elemental quantities are similar for several samples colleted in an industrial plant at different times. Moreover, the high amount of soluble salts (NaCl, KCl, calcium compounds) may constitute a major problem and should be taken into account for all management strategies. The solubility in water is very high (more than 24% for a solid/liquid ratio of 10) and thus the possible utilizations of this residue are very limited, creating difficulties also in the ordinary treatments, such as in solidification/stabilization with binders.
