摘要： PROBLEM TO BE SOLVED: To reduce the inclusion of the decomposition product of a heat medium and thereby enable the reuse of a useful component as a raw material by bleeding an organic halide gas contained in a foam resin and separating/recovering each of components from mixed waste in a heat medium by specific gravity difference. SOLUTION: Mixed waste including a foam resin containing an organic halide which is used as a heat insulation material in a refrigerator is loaded into a sealing machine 2 which stores a heat modium 1 at a normal temperature, then is sent into a thermal reaction tank 3 to uniformly heat the heat medium 1 at a specified temperature of 300 deg.C or less using a heater 11 arranged encircling the outer wall of the thermal reaction tank 3, and thereby, the foam resin included in the mixed waste is softened or fluidized to bleed an organic halide gas contained in the foam resin. Further, the gas is quenched to separate the components originating from the mixed waste in a specific gravity separation tank 16 into a molten metal 13 and a slid matter 14 by specific gravity difference in the heat medium 1.

摘要： PROBLEM TO BE SOLVED: To provide an apparatus for liquefying waste plastics which consists of a distillation means for recovering an oil by heat-decomposing a feedstock containing a plasticizer, a halide and a waste plastic and a specified means for preventing the stoppage of the pipes with the decomposition product of the plasticizer to prolong the life of the apparatus as a whole. SOLUTION: This apparatus consists of a distillation means, desirably a main tower 1 and a stripper 7 or a plurality of distillation towers wherein a feedstock containing a plasticizer (e.g. DOP), a halide (e.g. PVC) and a waste plastic is heat-decomposed and the produced oil is recovered. The apparatus is further provided with a cooling means 8 for separating the decomposition product (e.g. phthalic anhydride) of the plasticizer from the heat decomposition gas or liquid. Namely, phthalic anhydride as the product of decomposition of the plasticizer has a boiling point of 285 deg.C and is distilled together with an oil 6-3 equivalent to a heavy gas oil when distilled. This mixture is sent to the condenser 8, where the phthalic anhydride is crystallized. The crystallized phthalic anhydride is separated and sent to a tank 9 and recovered. Thus, the pipes can be prevented from being stopped with the phthalic anhydride.

摘要： PROBLEM TO BE SOLVED: To treat waste plastics while recovering additives and inhibiting the formation of organic chlorine compounds by heat-treating waste halogenated plastics containing plastic additives repeatedly under specified conditions. SOLUTION: A waste halogenated plastic (e.g. PVC) containing plastic additives (e.g. DOP plasticizer) is heat-treated at a first temperature which is equal to or higher than the temperature at which the halogenation does not occur and is equal to or lower than the temperature at which the additives are decomposed desirably in a stream of a gas medium (e.g. nitrogen gas) to evaporate the additives and to separate the waste plastic. The waste plastic is heated at a second temperature higher than the first temperature to separate the halide (e.g. HCl) from the waste plastic. If required, the waste plastic is further heat-treated to recover oils.
