“…Mangizvo [28] identified in a study of the Mucheke MSW dumpsite in Masvingo, Zimbabwe, that soil within a 50 m radius had been contaminated by trace metals of lead, iron, copper, zinc, and phosphorus. These heavy metals migration and temporal distribution concentrations of heavy metals contaminants [29][30][31] deserve further study to reduce the infiltration into the ecosystem. Moreover, incineration of MSW to generate energy is one of the traditional methods of dealing with combustible waste efficiently because it reduces the volume and mass of MSW.…”

“…Moreover, incineration of MSW to generate energy is one of the traditional methods of dealing with combustible waste efficiently because it reduces the volume and mass of MSW. Although heavy metals are inert and give off no energy when they are incinerated, the high temperatures of a MSW furnace cause metals to partially volatize, resulting in release of toxic poisonous fumes and fly ash [29][30][31][32]. In addition, it has drawbacks as well particularly hazardous emissions (NOx, SO x , HCl and harmful organic compounds) [14,[33][34][35] and harmful process residues [36].…”

“…In addition, it has drawbacks as well particularly hazardous emissions (NOx, SO x , HCl and harmful organic compounds) [14,[33][34][35] and harmful process residues [36]. Incineration of MSW generates fly and bottom ashes which release leachable toxic heavy metals, dioxin, furans and volatile organic compounds [24,25,29,37]. The thermal treatments may be very promising remedy for control dangerous emission of furan, dioxin and other harmful emissions but choice of the thermochemical conversion is very important.…”

Thermal treatment applications towards production of energy from raw and pre-treated municipal solid waste (MSW) are continuously growing context in contemporary waste-to-energy technology. The quality of MSW needs an improved analysis to enhance her choice of energy exploitation and environmental assessment of fly and bottom ashes associated with thermochemical conversions. The MSW were collected from municipal solid waste disposal facilities (MSWDF) in Cape Town to investigate heavy metals distributions in MSW. The MSW were pre-treated to improve the quality of MSW. The 7700 Series quadrupole ICP-MS solution method was used to determine concentrations and distributions of some heavy metals from MSWDF in Cape Town. This study further predicted distributions of heavy metals in fly and bottom ashes by a model. The results showed that accumulation of high concentrations of heavy metals in bottom ash residue could be a good remedy for heavy metals control. The heavy metals (especially Pb, Zn and Hg) emissions could be technically monitored and controlled from escaping to urban air-sheds atmosphere and prevent from their consequential secondary environmental and health implication.

“…Regarding visible scientific uncertainties and the fact that the FA matrix is analytically challenging, thoroughly validated analytical approaches are indispensable. Not at least, to investigate the heterogeneity of residues of different incineration plants and variations over time within the same plant, that both were not yet investigated in detail [26]. Therefore, in a subproject of the initiative, the following aspects were addressed: (i) a best practice advice for routine sample preparation and multi-element analyses for a comprehensive investigation of (trace) element content of MSWI-FA, (ii) the temporal heterogeneity of key parameters and element content of 65 elements (Ag, Al, As, Au, Ba, Be, Bi, Ca, Cd, Ce, Co, Cr, Cu, Dy, Er, Eu, Fe, Ga, Gd, Ge, Hf, Hg, Ho, In, Ir, K, La, Mg, Mn, Mo, Na, Nb, Nd, Ni, P, Pb, Pd, Pr, Pt, Rb, Re, Rh, Ru, S, Sb, Sc, Se, Si, Sm, Sn, Sr, Ta, Tb, Te, Th, Ti, Tl, Tm, U, V, W, Y, Yb, Zn, Zr) from sampling per hour, daily and monthly (1 year), (iii) the mobilisation potential of these metal(loid) s with three diferent eluents in standardised laboratory experiments and (iv) the supply security as well as the economic demands.…”

Municipal waste incineration fly ashes: from a multi-element approach to market potential evaluation

et al. 2020

View full text Add to dashboard Cite

Background: Fly ashes from municipal solid waste incineration contain significant amounts of (technology critical) elements. Processes to recover Cu or Zn are already in practice, but it still remains difficult to evaluate the full secondary resource potential of the ashes. One reason is the absence of a worldwide comparable analytical basis for detailed market analyses. To encounter this, (i) an advice on how to analyse 65 elements after microwave-assisted digestion by ICP-OES and ICP-MS is delivered, (ii) the heterogeneity (hours to annual cycle) is evaluated for a incineration plant, (iii) leaching efficiency with three different eluents and (iv) the market potential of the elements as commodities are evaluated. Results and conclusions: Aqua regia digestion was found to be sufficient to evaluated the recovery potential; except for the mass constituents Al, Si, Sn, Ti and the trace components Cr, Hf, Nb, U and W, for which HF-containing digestions delivered better recoveries. On different time scales, ashes were very homogenous and HCl-as well as H 2 SO 4-supported leaching delivered, satisfying results within an hour (exceptions are, e.g., Bi and Sb). By applying characterisation factors of the life cycle assessment impact category "Resource depletion-minerals and metals" supplemented by the list of critical raw materials of the EU: Ag, Bi, Cd, Ga, In and Sb are most interesting elements to be recovered in future activities.

“…[3][4][5] Addition of sorbent clays, such as zeolite and bentonite, in the mix-design of a construction material enables the immobilization of toxic elements. 4 Identification and quantification of the chemical elements contained in leachates can be acquired by various instrumental techniques: atomic absorption spectrometry (AAS) 6 , optical emission inductively coupled plasma spectrometry (ICP-OES) 7 , inductively coupled plasma-mass spectrometry (ICP-MS) 8 , and Xray fluorescence spectrometry (XRF). 9 Energy dispersive X-ray fluorescence (EDXRF) method is extensively being used in the environmental protection 10 , and construction materials studies [11][12][13] , however the application of EDXRF for simultaneous multi elemental analysis of the liquid samples and leachates is still sparsely investigated.…”

A modification of analytical procedure for energy-dispersive X-ray fluorescence (EDXRF) quantification of ten chemical elements (As, Ba, Cd, Co, Cr, Cu, Mo, Ni, Pb, Zn) in the leachates obtained from cement binders was developed. Twenty-nine testing samples were used in the experiment. All samples were based on Portland cement. Fly ash of different origin, zeolite and bentonite were employed as mineral additives in the cement binders. Distilled water was used as leachate. Validation of the modified EDXRF procedure was conducted in terms of limits of detection and quantification, working range, linearity, selectivity, precision, trueness, and robustness. Traceability of the procedure was established using certified reference materials. Uncertainty of measurement was confirmed via ?in-house? laboratory validation approach. The expanded uncertainties for ten analysed elements were obtained for entire working range of EDXRF method. Robustness of the modified EDXRF procedure was assessed by means of chemometric in-house approach. The results obtained by modified X-ray fluorescence method were additionally correlated to those acquired by inductively coupled plasma optical emission spectrometry to confirm that EDXRF can be used as an effective and reliable alternative method for analysis of cement leachates.
