Sapporo Plastics Recycling Corp., Ltd. (SPR) which had started commercial operation of waste plastics liquefaction plant in 2000 when "The Containers and Packaging Recycling Law" had been enforced fully, has entered 10th year of operation. Only hydrocarbon oil has been recognized as recycled product derived from the waste plastics liquefaction plant of SPR by law. As a result, SPR has achieved high recycling rate, in addition, more than 90% of the recycled products have been reused in Hokkaido.
