Description of the Related Art Plastic wastes in general and industrial wastes and plastic mixtures discharged from a processing step have the following problems when measures are taken for their treatment and reuse. (1) When heat treatment such as incineration or oiling is performed, chlorine-containing plastics (such as PVC (polyvinyl chloride) and PVDC (polyvinylidene chloride)) are thermally decomposed to emit toxic hydrogen chloride gas. (2) In blast furnace blowing used as a reducing agent for the iron source, the permissible content of the chlorine-containing plastic must be 1% or less, so that the plastic waste cannot be directly recycled for blast furnace blowing. . (3) In the case of using as a recycled material, use of a plastic mixture is limited, so that it is necessary to reduce the impurity concentration as much as possible. (4) Landfill disposal of the plastic waste requires a large amount of land due to its large volume ratio.

Separation from PVC and PVDC is not possible. Also,
In order to float and separate plastic, a heavy liquid having a specific gravity of about 1.2 must be used. Furthermore, since a specific gravity liquid such as water is used for wet separation, wastewater treatment is indispensable, and the separated plastic must be dried.
On the other hand, in dry separation that combines detection and rejection mechanism,
Film-based plastics are difficult to align and have low throughput. In the case of wind separation and dry separation such as a vibrating sieve, it is possible to separate plastics and paper or plastics and metals that have a large difference in specific gravity, but the same plastics such as polyethylene and reinforced vinyl can be used. There is a problem that it is impossible to separate objects having specific gravity close to each other.
