    摘要： A process for purifying plastic from a waste stream can include separating a waste stream into two or more mixtures of flakes with each mixture containing one or more plastic types and performing an automated sorting process on the first mixture to increase the weight percentage of a plastic family in the first mixture. The separation process can include at least one process selected from the group consisting of density separation, electrostatic sorting, froth flotation, and density differential alteration. Prior to the automated sorting process, the first mixture can include at least 80% by weight of one or more plastics from the plastic family.

    摘要： Disclosed is a film-removal/sorting method for coated resin products, which comprises a film removal step (S5) of feeding a target material comprising a mixture of plural types of coated resin products each having a different softening temperature in at least either one of a film (2b) and a substrate (2a) thereof, into a film removing apparatus (20), and heating the target material in the film removing apparatus (20) up to a temperature allowing the substrate (2a) or the film (2b) of at least either one of the coated resin products to be softened in a non-molten state, so as to remove the film (2b) from the substrate (2a), and a sorting step (S9) of sorting the target material after being subjected to the film removal step (S5), between a film-free material (2A) consisting of the substrate (2a) of the coated resin product which has succeeded in removing the film (2b) therefrom, and an untreated target material (2B) consisting of the remaining coated resin products having residual films (2b). The film removal step (S5) and the sorting step (S9) are repeatedly carried out while increasing the temperature of the target material in the film removal step (S5) stepwise within a temperature range equal to or less than a highest one of softening temperatures of the films (2b) and the substrates (2a) of the coated resin products.
