Abstract
Sapporo Plastics Recycling Co., Ltd. (SPR) and Rekiseikouyu Co., Ltd. had developed and put to practical use of the liquefaction plant for municipal waste plastics including PVC and PET, and maintaining a high rate of making to oil, and waste plastics oil making technology to have done considerable results though the processing of making to these liquefaciton plants had passed six years or more since it began to have driven. The feedstock recycling that returns the generation light oil of these liquefaciton plants as a raw material in the oil refinery (Japan Energy Corporation) is started that becomes the first in the Japan in April, 2004, and this also continues the stability driving well. In addition, progress to the technology that does the feedstock recycling can expect the waste plastics cracked oil, and the prospect that the feedstock recycle by the simple waste plastics liquefaction plant towards in the future is realizable by this will be acquired.
