In 1996, the first commercial scale pyrolysis plant for the municipal post-use plastics was built and started the operation in Niigata by the technology developed by Plastics Waste Management Institute. Second plant has started the operation in Sapporo by the technology developed by Toshiba Corporation from April 2000 when "Other Plastics" of the Containers and Packaging Recycling Law has been come into force. Both plants are fully-automatic continuous process treating the municipal post-use plastics containing PVC, PET and other plastics, and recycle all of the products and by-products to the fuel oil and other applications, in which light oil is feedstock recycled in the petroleum plant A serious problem of this business is that the enough quantity of waste plastics have not been supplied by The Japan Containers and Packaging Recycling Association due to it's higher bid cost. As the future expectation of this business considering the competitive cost and better recycling system, one shall be to build bigger capacity pyrolysis plant in petroleum purification factory and recycle the all product oils in the petroleum plant performing the permanent recycling between oil and plastics, and other method shall be to locally build small scale pyrolysis plant with low cost establishing the local recycling system.
