This paper describes that selective liquefaction characteristics of polystyrene, PS, in waste plastics and fuel characteristics of biodiesel fuel, BDF, liquefied PS as diesel fuel. Firstly, solubility of PS in BDF was predicted by analysis based on Hansen Solubility Parameters, HSP. From the result, it was evaluated that BDF will be a good solvent for PS. In experiment, expanded polystyrene, EPS, and polystyrene paper, PSP, were liquefied in soybean oil methyl ester. From the experimental result, it was found that the kinematic viscosity of liquid increases with an increase of PS concentration in BDF. It was clarified that the increase of kinematic viscosity of BDF liquefied PS was due to molecular weight of PS. The self-ignition quality is decrease with an increase of PS concentration in BDF. The BDF with EPS concentration of 2 mass% is little change as compared with neat BDF.
