PROBLEM TO BE SOLVED: To provide an odorless, lightweight, and thin sandbag for storage by using natural wastes such as wooden crushed materials and cereal wastes which have been treated as wastes. SOLUTION: Wooden crushed materials containing much cellulose and slowly decomposed used are alpha-treated to remove the cellulose beforehand. As an additive to increase weight and a volume by absorbing a water content, washed sand and a biodegradable high water absorbing polymer are mixed according to usage. Since a deodorizing yeast (Motoda Bio-Cycle KM2) in which charcoal powder is implanted is mixed, putrid odor and fermented odor are suppressed. Consequently, the degree of freedom of selecting a place for scrapping is improved. COPYRIGHT: (C)2007,JPO&INPIT
