Plastics are now indispensable not only in industries but for daily life because of their excellent convenience. Only in Japan, about 12.25 million tons of plastics were produced in 1993. On the other hand, the production of waste plastics in the form of industrial and municipal wastes reached 7.56 million tons in the same year. A greater part of the produced waste plastics are now disposed of by incineration and landfill. The incineration would however generate detrimental substances from burned-up plastics and emit them into the exhaust gas, while the landfill would reduce rapidly the residual capacity of the final repositories. Under the circumstances, the Law for the Promotion of Sorted Collection and Recommercialization of Plastics Containers and Packages is to be enforced in 2000 in Japan. Waste plastics liquefaction technology has become high-lighted and is presupposed to employ for the treatment of waste plastics other than PET bottles in the law for the reason that relatively wide variety of waste plastics can be processed in quantity by this technology. The Kubota Corporation has made R and D efforts relating to the plastics liquefaction technology for more than 4 years, and it is now entering the stage of its commercialization.
