“…Since the first municipal solid wastes (MSW) incinerator was imported from Japan and installed in Shenzhen in 1988, more than 140 incineration plants are now in operation or under construction in China (Bie et al, 2007). However, the heat value (LHV) of MSW in China is only around 4200 kJ/kg (Yan et al, 2006), which barely meets the lowest requirement of incineration. In recent years, some scholars proposed coal/MSW co-combustion to solve the above problem (You et al, 2008;Zhu et al, 2008).…”

The emission characteristics of Polycyclic Aromatic Hydrocarbons (PAHs) and their toxic equivalent (TEQ) concentrations during coal/municipal sewage sludge (MSS) co-combustion were investigated in a laboratory-scale drop tube furnace at temperatures in the range of 950-1250°C. The experimental results demonstrated that PAHs and their TEQ concentrations generated from 30/70 (MSS/Coal) co-combustion were lower than their linear calculated values. Meanwhile, the maximum reduction efficiency (46.09%) of the PAHs concentration was achieved at 1150°C. As for the TEQ concentration, the maximum reduction efficiency was as high as 57.77%. It was also observed that the PAHs concentration in flue gas during coal mono-combustion or 30/70 (MSS/Coal) co-combustion first increased and then decreased at 950-1250°C, and the maximum amount of PAHs occurred at about 1150°C. In the case of MSS monocombustion, the maximum PAHs concentration is 2.495 µg/L at 1050°C.

“…A number of studies on combustion processes, such as those that occur in municipal solid waste incinerators (MSWI) and hazardous waste incinerators (HWI), have been carried out in China. The concentrations, congener patterns, emission factors and gas/particulate phase distributions of PCDD/PCDF among different MSWI were investigated and compared widely (Chang et al, 2004;Ni et al, 2009;Yan et al, 2006). In recent years, some studies have also focused on unintentional POP emissions from ferrous and non-ferrous metal production, especially iron ore sintering, coke production and secondary non-ferrous metallurgy processes.…”

h i g h l i g h t s< Emission factors of unintentional POPs from copper metallurgy were determined. < Emission levels and variations of unintentional POPs were measured and compared. < Unintentional POP congener patterns in stack gas and fly ash samples are presented. < The raw material used was a key factor for unintentional POP emissions. < Copper metallurgy is an important emission source of unintentional POPs. a r t i c l e i n f o b s t r a c tField monitoring was conducted to update and develop unintentional persistent organic pollutant (unintentional POP) emission inventories for the copper metallurgy industry in China. In this study, emissions of six unintentional POPs comprised of polychlorinated dibenzo-p-dioxin and dibenzofuran (PCDD/PCDF), polychlorinated biphenyls (PCBs), polychlorinated naphthalenes (PCNs), hexachlorobenzene (HxCBz) and pentachlorobenzene (PeCBz) in stack gas and fly ash samples from primary and secondary copper smelters using different raw materials and technologies were measured and compared. Different concentrations, congener patterns and emission factors of unintentional POPs among four copper smelters were observed. Variations in unintentional POP emissions from several areas of a primary copper smelter were also investigated. The total emissions of unintentional POPs from primary and secondary copper production in 2010 in China were estimated respectively. These results provide a useful reference for the establishment of unintentional POP emission inventories and for policymakers to formulate control strategies to reduce unintentional POPs resulting from copper metallurgy.
