ABSTRACT:
A resin material is recovered for recycling from industrial waste of plastic film, unlike conventional methods, without requiring washing and drying the steps for removing foreign objects adhering thereto such as agricultural chemicals. A method for recovering a resin material from industrial waste film according to the invention comprises the steps of crushing waste film into crushed small pieces to be treated, applying a scraping impact force to the crushed small pieces to remove any adherent foreign objects and separate them from each other. Then, the separated crushed small pieces are size-regulated and for regeneration.
