In the present invention, the first optical sorting machine is used in one stage among the garbage to first classify the plastic and the non-plastic into the one-sided film vinyls and the objects (pet, pp, pe, ps and the like) Plastic bottles, cans, etc. to simplify the sorting process and expand the processing capacity. The plastic sorting and sorting in the first stage by the two-stage sorting process is carried out through a one- (Pet, pp, pe, ps), vinyl (EPR films) are classified into vinyl and EPR films by sorting, ps type 4) is a method and device for producing recycled products having high purity by repeatedly sensing and repeatedly sensing four kinds of plastics by materials by using a sensor by a third optical sorting machine A. |
