With industrial development, the use of electrical and electronic products made of low-specific-gravity and easyprocessing plastics has increased. As these products have been abandoned, environmental problems, such as Dioxine and Furan, have begun to arise. Accordingly, through long-time reviews and discussions, the EU has implemented the Restriction of Hazardous Substances (RoHS) and Waste Electrical and Electronic Equipment (WEEE) regulations. Additionally, the Stockholm Convention was adopted in April 2011 for wastes containing brominated flame retardants. Therefore, the Basel Convention issued technical guidelines on environment-friendly treatment for wastes containing brominated flame retardants. For Korea to respond to both the conventions and changing trends in international persistent organic pollutant (POP) management, proper management and treatment plans suitable to Korean circumstances are required. In this regard, the study identified domestic and international trends in environmental regulations and usages, obtained fundamental data for the management of wastes containing brominated flame retardants, and investigated the current status of waste generation in Korea. Based on the results, six target samples were selected and evaluated to see if they were heat-treatable through content analysis, three-component analysis, element analysis, calorific value analysis, and thermogravimetric (TGA) analysis. The results of the analyses were used to make a lab-scale incineration reactor, and the results of the TGA analysis became the basis for setting the incineration temperature ranges for experiments. After incineration, five general air pollutants (O2, CO, CO2, SOx, and NOx) and three components of BRFs in the emission gas and flooring were analyzed to identify if the PBDEs in wastes can be destroyed in a stable and environmental manner during heat treatment.
