It was sometimes discarded because it was released.

このため、ゴム・ウレタン類とその他（プラスチック、金属等）を極めて効率的に分離、除去する方法が切望されている。   For this reason, a method for separating and removing rubber / urethanes and others (plastics, metals, etc.) extremely efficiently is desired.

特許文献１では、水分などの液体成分や非プラスチック成分を含むプラスチック混合物から、プラスチック成分を効率よく高収率で分別処理できるシステムとして、気流を用いることが提案されている。   In Patent Document 1, it is proposed to use an air flow as a system capable of efficiently separating a plastic component at a high yield from a plastic mixture containing a liquid component such as moisture and a non-plastic component.
