To provide a method and an apparatus in which a fibrous component and a resin component of a waste product including a fibrous layer and a resin coating layer such as waste wall paper can be separated and recovered at high precision and high efficiency.
A wind-force separator 7 in which a circular plate 20 is horizontally supported in a vertically cylindrical separation column 15 having an upper discharge port 17 for suction and a lower discharge port 18 serving also as an air supply port disposed therein so that a ventilation gap 24 is present between the periphery of the circular plate 20 and an inner wall surface of the separation column 15, a tip end opening 19c of an air transport pipe 19 inserted from outside of the separation column 15 is placed in a center portion of an upper surface of the circular plate 20, a ground material of waste wall paper is transferred to the center portion of the upper surface of the circular plate 20 through the air transport pipe 19, a resin component that is a component having a high specific gravity in the ground material is dropped from the periphery of the circular plate 20, and a fibrous component that is a component having a low specific gravity in the ground material is sucked riding on an air stream introduced from the lower discharge port 18 and moving upward inside of the separation column 15 from the upper discharge port 17 to discharge it.
