“…However, the EF value for Cu in PM10 sample was relatively small in spite of its large MIF value. In previous work, 21 the present authors reported on the kinetic behaviors of the elements in the industrial waste incineration ashes, which is one of anthropogenic emission sources of PM10. According to the results in previous work, 21 Cu was not very much partitioned in fly ash during the incineration processes, even though Cu was totally enriched in industrial waste incineration ashes.…”

According to the results in previous work, 21 Cu was not very much partitioned in fly ash during the incineration processes, even though Cu was totally enriched in industrial waste incineration ashes. Therefore, it should be considered that Cu is not very much emitted to ambient air from waste incinerators compared to other elements, in spite of the wide use of Cu in industrial production.…”

“…Notably, valuable elements, like Zn and Cu, and some potentially toxic elements (Pb and Cd) were moderately enriched in all samples from both plants. The EF of Zn, Cu, and Pb were comparatively lower than the values (EF < 100) reported by Fujimori et al (2004). Westerhoff et al (2015) reported lower Cu and Pb enrichments and Lanzerstorfer (2017) also reported lower enrichments.…”

Introduction: Municipal Solid Waste Incineration (MSWI) plants generate significant amounts of solid end-products, such as bottom ash (BA), containing potentially toxic elements like Cr, Ni, As, Cd, and Pb, base elements (e.g., Si, Al, Fe, Ti, Cu, and Zn), and other technology-critical elements (TCE), such as Co, Ga, Mg, Nb, P, Sb, Sc, V, Li, Sr, and REE. The accurate determination of these elements in anthropogenic wastes and the assessment of their removal are crucial for the circular economy.Methods: This paper aims to characterize BA samples from two Italian MSWI plants (named FE and FC) by X-ray fluorescence (XRF) and comparatively assess the removal of a selection of elements using the aqua regia digestion (ARD) method, followed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) analytical determination.Results and discussion: According to the XRF analysis, Ca, Fe, Al, Mg, and Na had high concentrations in BA, and their contents increased with decreasing particle size in both FE and FC samples. The Enrichment Factor (EF) based on the upper continental crust’s average values of Zn, Cu, and Pb was high (EF > 30), while Cr, Ni, and As were scarcely enriched (EF > 1), and REE enrichment was very low (EF < 1). In both FE and FC plants, the Degree of Elements Extractability (DE) was high (>80%), especially in the fine-grained fractions of MSWI bottom ash. The Enrichment Factor (EF) based on the upper continental crust average values of Zn, Cu, and Pb was high (EF > 30), while Cr, Ni, and As were scarcely enriched (EF > 1), and REE enrichment was very low (EF < 1). The bibliometric analysis helped highlight research trends in the assessment and treatment of MSWI-BA, discriminating the literature impact on environment/health issues and recovery/recycling strategies for the circular economy associated with the MSWI-BA material.Conclusion: Although higher data coverage is needed, the present study suggests ARD as an effective method for better understanding the environmental impact and recoverability of useful elements from anthropogenic materials like MSWI bottom ash.
