To provide a method for recovering a thermoplastic resin foamed base material, from which a fiber component made of a skin nonwoven fabric or a skin woven fabric of an interior finishing material for an automobile containing at least the skin nonwoven fabric, the skin woven fabric and the thermoplastic resin foamed base material is substantially separated, as a resin material.
The method for recovering the thermoplastic resin foamed base material comprises the steps of grinding a waste material and/or an end material generated at a molding time of the interior finishing material for the automobile; wind-separating the fiber component in the ground material by a dust separating unit of a specific structure of various type and its combination; and recovering the thermoplastic resin foamed base material from which the fiber component made of the skin nonwoven fabric or the skin woven fabric of the interior finishing material for the automobile is substantially separated, as the resin material.
