<p>PURPOSE:To efficiently produce a pellet-shaped synthetic resin regenerated raw material from waste of a foamed polystyrene product widely used as a packing material of an electric product or a transport container of marine products. CONSTITUTION:A recovered foamed polystyrene product is ground and subsequently compressed while heated to temp. generating no change in the properties of the product and facilitating the compression thereof to be contracted until the volume ratio of the product becomes about 1/30-1/15. The air, gas and moisture contained in the foamed polystyrene product are discharged and the product is formed into a thin plate in a non-foamed state or a state near thereto to be broken into fine pieces.</p> |
