The catalysts and the addition methods into rapeseed oil were developed to increase dissolution rate of UP (unsaturated polyester) waste. The dissolution experiments of UP were carried out in vegetable oil added six kinds of catalysts including KOH. The dissolution rate was 1.6wt%/min without catalyst. On the other hand, the dissolution rate was increased to 3.6wt%/min with catalyst. The vegetable oil dissolved UP using catalyst was analyzed by FTIR measurement. The difference of dissolution oil with or without catalyst was not observed. Diesel oil was produced from the vegetable oil dissolved UP as recycling method. Furthermore, the raw material had been collected by cooling of volatilization substance during the dissolution of UP.
