で加熱する。EXAMPLE A method for selecting a metal material for plastic waste according to the present invention will be described. An example will be described in which used salad oil is used as edible waste oil and polyethylene-coated electric wire is used as plastic waste having a metal material. First, salad oil is put in a metal container, and the metal container is heated by a gas combustion heating device until the oil temperature reaches 170 ° C to 175 ° C.

Continue stirring the salad oil. At this time, the oil temperature of the salad oil is maintained at 170 ° C to 175 ° C. Then, about 20 minutes after the polyethylene-coated electric wire was put into the salad oil, the polyethylene of the electric wire was dissolved in the salad oil,
The metal core wire is exposed. At this time, the salad oil is transparent, the polyethylene is completely dissolved in the salad oil, and no plastic chiller can be formed.

ばバーナ噴霧燃焼させることができる。Therefore, the heating of the salad oil is stopped and the salad oil is naturally cooled. Then, when the salad oil is cooled to room temperature by natural cooling, the metal core wire is taken out from the salad oil, so that it is easy to take out and collect only the metal core wire that is the metal material from the plastic waste that is the polyethylene-coated electric wire. Becomes In addition, since plastic, which is polyethylene, is dissolved in edible waste oil, which is salad oil, the edible waste oil can be subjected to the same treatment method as heavy oil combustion, for example, burner spray combustion.
