Filed: 2002-12-03
Abstract: <P>PROBLEM TO BE SOLVED: To provide a waste material compression device capable of repeatedly charging and compressing waste materials while suppressing restoration and expansion of the once-compressed waste materials, reliably miniaturizing the waste materials, and increasing the volume reduction ratio of the waste materials in a packed condition.  <P>SOLUTION: A restoration suppression means 30 which is protruded as necessary is disposed in a storage space. After the charged waste materials are compressed, the restoration suppression means is protruded in the storage space to fix the waste materials, and the compression condition is continued. Even when the compression condition by a pressing unit 20 is released, more waste materials can be stored in the storage space as compared with a case in which waste materials are simply charged and compressed repeatedly without restoration and expansion of the waste materials stored in the storage space. In addition, more waste materials can be collectively packed in the same volume in a packing step, and the cost for treating waste materials is suppressed.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
