摘要:
It is an object of this invention to efficiently recycle a plastic resin material used in a process cartridge. To achieve this object, in a method of recycling a plastic material of a process cartridge, the process cartridge is crushed in a crushing step while particles such as toner are collected by suction, particles including toner are further separated in a screening step, metal materials are separated in a magnetic selection step, a drum magnetic selection step, and an eddy current step, particles including toner and foreign matter are separated in an air selection step, a secondary crushing step, a peeling step, and a dry gravity separation step, and a plastic material having a specific density is separated in a color selection step.
