In this study those currently operating pyrolysis oil plant were selected for the investigation. The yield of the oil and fuel was assessed for its use as fuel and the char component analysis, and the reaction time to collect contaminants collected and analyzed. As the result, about 43.5 % of the oil was yielded and oil could be used as an alternative fuel. And emission of Dioxin and pollutants was analyzed. The concentration of dioxin average was 0.207 ng I-TEQ/S㎥. The result satisfied the requirement however the emission concentration of CO and HF was exceed. Therefore the appropriate pollution control facility should be required.
