The daunting effects of persistent organic pollutants on humans, animals, and the environment cannot be overemphasized. Their fate, persistence, long-range transport, bioavailability have made them an environmental stressor concern which has attracted interest research community. Concerted efforts been by relevant organizations utilizing legislative laws to ban their production get rid completely for sake public health. However, they remained refractive in different compartments environment. is majorly a function anthropogenic activities. Landfilling incineration are among earliest classical means remediation waste; however, not sustainable due seepage contaminants landfills, release toxic gases into atmosphere energy requirements during incineration. Other advanced waste destruction technologies explored degradation these recalcitrant pollutants; although, some efficient, but limited high amounts consumption, use solvents hazardous chemicals, capital operational cost, lack trust. Thus, this study systematically reviewed contaminant technologies, efficiency, feasibility. Finally, based techno-economic feasibility, non-invasiveness, friendliness; radiation technology can considered viable alternative all matrices at bench-, pilot-, industrial-scale.

Municipal solid waste incineration fly ash (MSWIFA) is of great value in resource utilization. Harmless pretreatment a crucial prerequisite for the utilization MSWIFA. The detoxification process step harmless This includes polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), which are among most toxic substances to humans other living organisms. Low-temperature degradation technology has broad prospects engineering applications due advantages low technical difficulty operating costs. work conducts pilot test on 17 PCDD/Fs MSWIFA at temperatures. investigates effects reaction temperature oxygen content Furthermore, based perspective utilization, an analysis proposal made judge effect low-temperature thermal treatment Further, taking soil sludge field as application scenario, feasibility after analyzed. flotation markedly reduces both carbon levels hydrothermal method facilitates dioxins while introducing significantly lowers required treatment. can enhance rate reduce demands equipment. results indicate that effectively degrade MSWIFA, satisfying requirements some scenarios. Notably, evaluating should satisfy residue different industries achieve certain detoxication efficiency.
