Abstract

Sapporo Plastics Recycling Co., Ltd. (SPR) which started commercial operation of liquefaction plant for waste plastics containing PVC and PET in 2000 has been entered into 9th year this year. Presently, thermal degradation residue and hydrochloric acid other than hydrocarbon oil have been produced as a by-product. As a result, SPR has achieved high recycling rate, in addition, more than 90% of the recycled products have been reused in Hokkaido.
