        Polychlorinated naphthalenes (PCNs), one of Persistent Organic Pollutants (POPs), and are colorless crystalline substances with similar structure and physical and chemical properties with PCB (polychlorinated biphenyl), and are produced by the chlorination of naphthalene. PCN is one of POPs are rarely degraded in the environment; consequently, they negatively impact the environment by threatening human health and the ecosystem. In this study, the potential of a stable treatment for lab-scale-incinerated waste containing PCNs was evaluated. For this study, waste containing PCNs were selected as the surface coating agent, mixed sample, and technical sample. The results revealed that when the PCNs concentration was 34.552 ~ 2,582.463 ng/g, the concentrations of Mono-CN and Tetra-CN were higher than those of other homologues. The incineration treatment conditions were derived by measuring three parts, after which the elemental composition was analyzed and the calorific value, theoretical air content, and residence time were calculated. Using the temperature of the target sample, thermogravimetric analysis revealed that the incineration treatment can be achieved at the incineration temperature of the existing incineration facility via weight change. Therefore, the incineration temperature was set between 850 and 1,100℃; however, the incineration temperature of the sample containing a high concentration of PCNs was set at 350, 500, 850, and 1,100℃. At 350 and 500℃, high concentrations of CO and NOx were observed, which could be attributed to incomplete combustion. Furthermore, heat-sensitive PCNs showed a de-chlorination reaction between 200 to 440℃. In addition, the decomposition rate (DRE) slightly increased according to the incineration temperature increase.
