“…Chang and Ku [23] elucidated that more than 80% of Hg and As were transferred into the gas phase, while Cd, Cr, Cu, Ni, Pb, and Zn mainly partitioned in the bottom ash and APC residues. Similar results were obtained by Kuo et al [24] on the partitioning behavior of Al, Cd, Cr, Cu, Fe, Pb, and Zn in a large MSW incinerator in Taiwan, with Cd primarily enriched in APC residues and other six metals concentrated in bottom ash. Based on material flow analysis on the bottom ash, boiler ash, gas cleaning residues, and exhaust gas, Belevi and Moench [21] suggested that Si, Fe, Co, Cr, Mn, Ni, P, Al, Ca, Mg, Na, Ba, Li, Ti, and K were transferred to the flue gas mainly by entrainment (without evaporation process), influenced by their occurrence and distribution in the input waste, while F, Cu, Mo, Pb, Sn, Zn, Br, Sb, C, S, Cl, As, Cd, and Hg were migrated to the gas by evaporation, determined by physical and chemical conditions as well as kinetics.…”

“…Waste to energy (WtE) plants produce typically between 200 and 300 kg BA per 1 Mg of burnt waste, (Vehlow and Seifert 2012), i.e. it represents between the 10 and 35 % of the amount of incinerated waste (Kuo et al 2007) and about 75-95 % in weight of the total residues generated . In order to evaluate how MSWI solid residues could have a second-life functionally, it seems to be fundamental to exploit the physicalchemical properties and characteristics.…”

Incineration has become an attractive option for municipal solid waste (MSW) management, due to its several benefits. In fact, it allows volume and mass reduction of waste and energy recovery from MSW combustion. Nevertheless, MSW incineration (MSWI) produces three main types of residues: bottom ash (BA), fly ash (FA) and air pollution control (APC) residues, which require an adequate handling. BA is the most significant by-product from MSWI and is generally considered as nonhazardous waste. Instead, FAs are included as hazardous wastes because are characterised by high content of chlorides, heavy metals and organic compounds. The aim of this paper was to examine the characteristics of MSWI solid residues, the management and reuse of these wastes and their environmental assessment from a life cycle perspective. It was noted that the main components that make up the residues are lead and zinc as well as oxides, mainly CaO, SiO 2 and Al 2 O 3 . Furthermore, it is necessary to take into account the presence of PCDD/F which characterised FA and APC residues, mainly due to chlorine content. Chemical and physical properties of those residues make possible their reuse as construction material, as adsorbent, as well as in geotechnical and agricultural applications. Nevertheless, several studies have demonstrated that a drawback of the reuse of MSWI residues is the existence of heavy metals in elevated concentrations which may affect the environmental quality. In this regard, many studies were aimed to assess the environmental impact related to the introduction of MSWI residues as secondary material in several fields of application.

“…The spatial distribution of such metal stocks is extensive, since humanmanipulated metals may accumulate anywhere human activity makes an impact, intentionally or not, from the deep sea all the way to space. (Wang et al, 2007;Kuo et al, 2007) and copper (Graedel et al, 2004;Kuo et al, 2007). From all stocks, secondary metals dissipate into the surrounding environment (land, sea, air or even space).…”

Stocks of finite resources in the technosphere continue to grow due to human activity, at the expense of decreasing in-ground deposits. Human activity, in other words, is changing the prerequisites for mineral extraction. For that reason, mining will probably have to adapt accordingly, with more emphasis on exploitation of previously extracted minerals.This study reviews the prevailing concepts for mining the technosphere as well as actual efforts to do so, the objectives for mining, the scale of the initiatives, and what makes them different from other reuse and recycling concepts. Prevailing concepts such as "urban mining," however, are inadequate guides to the complexity of the technosphere, as these concepts are inconsistently defined and disorganized, often overlapping when it comes to which stocks they address. This review of these efforts and their potential is therefore organized around a new taxonomy based on the umbrella concept technospheric mining, defined as the extraction of technospheric stocks of minerals that have been excluded from ongoing anthropogenic material flows.An analysis on the basis of this taxonomy shows that the prevailing mining initiatives are generally scattered and often driven by environmental factors, in which metal recovery is viewed as an additional source of revenue. However, development of technology, specialized actors and new business models and policy instruments, could lead to technospheric mining operations becoming a profit-driven business.
