<p>The present invention relates to a biodegradable polystyrene capsule for molded product of polystyrene foam and to a method for manufacturing the same. The inventive biodegradable polystyrene capsule comprises a powder formed of a biodegradable material and a coating layer of foamable polystyrene resin formed on the surface of the powder. Products made from the biodegradable polystyrene capsule may variously used for packing material, insulating material, disposable products, etc. since the dame have great mechanical and physical properties such as impact-resistant property, anti-breakability, etc., and, since the biodegradable material inside the capsule is decomposed by microbes in the nature after a certain period, the efficiency of destruction is considerably improved, so it is possible to minimize problems of soil, air, and sea pollution caused by fill-in or incineration of the conventional wastes of molding foam product.</p> |
