“…On the other hand, the environmental effects of waste incineration often become a public concern issue. Some studies reported that a lot of vegetables produced near certain incinerators had relatively high levels of dioxins, and the furan equivalent concentration of breast milk in local residents was significantly higher than those exposed to low-pollution concentrations [10][11][12][13][14]. Javier García-Pérez et al, 2013 believed that incineration pollution was associated with increased risk of abortion in surrounding populations [15].…”

Disposal of municipal solid waste (MSW) has become increasingly challenging. In this study, we used life cycle assessment (LCA) to evaluate environmental impacts and financial performance of a new approach for MSW disposals, namely All-components Resource Recovery (AcRR), which is based on automatic sorting. We compared AcRR with the standardized Waste-to-Energy incineration (WtE) to provide decision-making support for MSW management. The results show that WtE and AcRR are both good MSW resource treatment methods. Through MSW disposal, WtE generates electricity, while AcRR generates secondary resources such as metals, plastics, pulp and organic fertilizers. WtE releases trace amounts of HCl, PM10, heavy metals, dioxins and dust, while AcRR does not produce such pollutants; AcRR produces more odor gases such as SO2 and H2S. AcRR produces four environmental issues, i.e., Global Warming, Acidification, Photochemical Ozone Synthesis, and Eutrophication, each of which has a smaller impact than WtE; WtE has two more impacts than AcRR: Human Toxicity and Soot and Ashes. The total environmental impact potential of WtE is 3.38 times that of AcRR, and the greenhouse gas emission equivalent is 6.82 times that of AcRR. The cost of construction and operation of AcRR is lower than that of WtE, while the net profit of AcRR is much higher. In conclusion, AcRR is able to screen the mixed MSW into various secondary resources with less environmental emissions and environmental impacts and better financial performance; it may be a promising MSW disposal approach, especially for small cities, but a corresponding supporting industrial system is needed.

Open combustion of solid waste is one of the main sources of the emission of dioxin and dioxin-like compounds (DLCs). Ambient dioxin will eventually undergo depositions on soils and tree leaves. Pine trees have shown an ability to store dioxin in their needles allowing biomonitoring of dioxin atmospheric concentrations. Infiltration can transport dioxin to greater depths into the ground, on one hand, while vaporization can allow dioxin to return back to the atmosphere on the other. Several studies evaluated the migration of dioxin between two compartments; however, few studies have attempted to understand the fate of non-conservative PCDDs and PCDFs in an unsteady state system of more than two mediums. This study focused on the transportation of dioxin between polluted trees and the underlying soil through the effect of rain water. For approximately 10 years, pine trees in this study have been exposed to emissions generated by the open combustion of municipal solid waste (MSW) from a fixed location. Soil samples located further from the point source had generally lower dioxin concentrations. Dioxin concentrations were correlated to distance from the source using least square regression. Soil samples below contaminated trees had dioxin concentrations 10-35% greater than the calculated measurements for the same spots using the regression model. By detecting these spikes in concentrations, it was possible to identify pools of dioxin found directly under the contaminated trees-indicating a rinsing effect of rain water on the stored dioxin on the trees' needles.
