This research was performed to evaluate the physicochemical characteristics of waste oil, waste solvent, and waste paint as waste derived fuel (WDF) feeding materials and WDF. Low heating values (LHVs) were in the ranges of 8,313.8 ~ 10,989.5 kcal/kg for waste oil, 4,109.1 ~ 9,890.6 kcal/kg for waste solvent, 5,733.7 ~ 8,051.0 kcal/kg for waste paint, and 5,184.2 ~ 10,679.0 kcal/kg for WDF. Sulfur contents showed 0.010 ~ 1.900% for waste oil, 0.000 ~ 0.073% for waste solvent, 0.004 ~ 0.581% for waste paint, and 0.001 ~ 0.700%, respectively. Chloride contents showed the ranges of 2 ~ 4,870 mg/kg for waste oil, 0 ~ 12,900 mg/kg for waste solvent, 0 ~ 10,700 mg/kg for waste paint, and 'not detected' ~ 4,070 mg/kg for WDF. Cd, As, and Hg were detected minimally in a few sample only. Other heavy metals showed below standard permission value for WDF. Feeding materials for WDF showed greatly different characteristics within even same sorts of wastes. And, as results of LHV, S, Cl, and heavy metal contents, WDF samples investigated in this research satisfied the standard permission value for WDF.
