Abstract Recently, the development of liquefaction equipment, which reuse waste expanded polystyrene (EPS) as a fuel, has been promoted, and some of them are being commercially use. However, it is hard to popularize them, because they are larger and far more expensive than the EPS melting machines which are usually used in the markets and department stores. Consequently, to develop a substitute system for the melting machines, a technique to liquefy EPS at 200 deg C (at one half the temperature of the former equipment) was tried. The realization of this method will make it possible to save energy, to improve safety, and to make downsize the liquefaction equipment. The objective of this study is to examine the characteristics of viscosity versus temperature and M subn. of recycled oil that is liquefied at a temperature lower than before. The other objective is to consider the optimum conditions of recycled oil production with viscometric property as heavy oil. A burning test for the recycled oil produced by this optimum method was carried out.
