“…The mineral and crystalline phases in the WBA (see Table 3) were identified by powder X-ray diffraction analysis (XRD) using an Expert diffractometer (Panalytical, Netherlands). It should be emphasized that while some mineralogical phases usually considered in the literature were identified (Chimenos et al, 1999;Gonzalez et al, 2017;Xia et al, 2017), the initial sample presented an amorphous phase because of its glass content, which is the main component of the WBA (del Valle-Zermeño et al, 2017b), and therefore could not be identified by XRD. However, this packaging glass (primary glass) is one of the precursors of secondary glass, which is newly formed during the combustion process at high temperatures.…”

“…Firstly, some critical metals, such as the REEs, are in extremely low concentrations in WBA (Allegrini et al, 2014;Morf et al, 2013), and their concentrations in the leachates would be below the ICP-MS limit of detection. Secondly, there are some valuable metals (e.g., Al, Cu and Ni) which are not considered critical but their abundance in the sample makes their recovery economically feasible (Gonzalez et al, 2017;Morf et al, 2013). Finally, there are also other valuable metals, such as Ag and Au, whose high prices make their recovery feasible, although their contents are not very high.…”

“…En outre, le module SURFACE, a été utilisé pour définir la complexation du Ni, du Cu et du Pb avec la matière organique selon l'approche développée par Chatain et al, (2013). En effet, de nombreuses études ont confirmé que la matière organique forme des complexes avec ces 3 ETM (Bruder-Hubscher et al, 2002 ;Dijkstra et al, 2006 ;Gonzalez et al, 2017 ;Meima & Comans 1999 ;Todorovic & Ecke 2006 ;Verbinnen et al, 2016 ;Xia et al, 2017 ;Yao et al, 2017). Pour modéliser ce phénomène, le modèle à deux couches généralisé avec le calcul non explicite de la composition de la couche de diffusion de Dzombak & Morel (1990) incorporé dans PhreeqCI a été utilisé.…”

Mineral trace elements (MTE) constitute an environmental restriction on the recycling of municipal solid waste incineration-bottom ash (MSWI-BA). The study of the speciation of MTE and the factors that control their release allows to predict their behavior under different environmental conditions and, consequently, suggest different actions to expand the management of MSWI-BA.A geochemical modeling led to a better understanding of the speciation of MTE. In this study, target elements were barium, copper, lead, nickel and zinc and the factors that control their release were identified.The results show that the leaching of metals as a function of pH mainly depends on the mineralogical phases. On the other hand, the organic matter has an influence in the leaching of MTE (for Ni, Cu and Pb notably); organic matter presents adsorbent or complexation properties. Les éléments traces métalliques (ETM) constituent une restriction environnementale pour le recyclage des mâchefers d'incinération des déchets non dangereux (MIDND). L'étude de la spéciation des ETM et des facteurs qui contrôlent leur mobilité permet de prédire le comportement des MIDND dans différentes conditions environnementales et de suggérer ensuite des actions pour élargir leur gestion. Une modélisation géochimique des MIDND a permis de mieux comprendre la spéciation des ETM. Dans cette étude, les éléments ciblés étaient le baryum, le cuivre, le plomb, le nickel et le zinc et les facteurs qui régissent leur mobilité ont été définis. Les résultats montrent que la lixiviation des métaux en fonction du pH dépend principalement des phases minéralogiques ; la matière organique joue également un rôle en tant qu'adsorbant ou complexant dans la lixiviation de certains éléments (Ni, Cu et Pb, notamment).

“…bioavailable. In order to investigate the metal content in fractions, including cadmium, lead and copper in bottom ash, the sequential extraction method is used [Yao et al, 2011;Gonzales et al, 2019;Haberl and Schuster, 2019). There are various procedures for the fractionation of metals, although one of the most economical ones is the BCR method (proposed by Standards, Measurement and Testing Programme, former Community Bureau of Reference).…”

The basic physicochemical properties such as: dry mass, pH, pseudo-total content of cadmium, lead and copper, were determined in the fresh bottom ash samples from a municipal waste incineration plant. In order to study fractional composition of the investigated heavy metals, the BCR method was used (F1 -acid soluble and exchangeable fraction, F2 -reducible fraction, F3 -oxidizable fraction, F4 -residual fraction). The average percentage of cadmium in particular fractions was as follows: , and in the case of copper F4(66.3%) > F3(22.1%) > F2(7.4%) > F1(4.2%). Among the studied metals, in mobile pool (F1-F3) the highest amount of cadmium was noted (72.8%); for lead it was 63.5%, and for copper 33.7% of the pseudo-total content.
