<p>PROBLEM TO BE SOLVED: To provide a granule usable for various kinds of purposes, capable of being subjected to a disposal treatment, and having flexibility, and further to provide a method for producing the granule. SOLUTION: This granule is obtained by attaching a surface material having the melting point higher than that of a core material, and the size smaller than that of the core material on the surface of the core material composed of a plastic or a rubber by fusion. The method for producing the granule is the method comprising fixing the surface material having a higher melting point and the smaller size compared with those of the core material to the periphery of the core material of the plastic or the rubber by melting the surface of the core material, and the method comprising heating many surface material to the temperature higher than the melting point of the core material, and bringing the surface material into contact with the core material.</p> |
