<p>PROBLEM TO BE SOLVED: To provide throw-away containers designed to be reduced to soil by spontaneous fermentation decomposition when the containers discarded after use are rested by mixing other plant fibers with strained lees of sweet potatoes of waste products, bagasse of corns, kaolian, etc., and industrial waste of knots scum, such as pulp sludge occurred as by product in papermaking plants and waste paper and molding the mixture to fiber boxes, winding cores or cylinders provided with fermentation decomposition germinability and working these moldings to electric appliances for power transmission or the winding cores of cable electric wires. SOLUTION: The bagasse and knots scum are used as raw materials. Glue is mixed therewith and the mixture is poured into metal molds. The molded goods are produced by solidifying the mixture and parting the moldings from the molds. Molds are otherwise formed by using paper boards for the outside surfaces and the mixture is poured therein and is molded to a planar form. The moldings are then dried to form the molded goods. These molded goods are subjected to surface waterproof finishing and are assembled to the power transmission appliances and the windings cores inconvenient to carry. When these appliances and cores are rested in the fields after use, the appliances and cores are gradually fermented and decomposed by rainwater and moisture to allow planted trees and other plants to propagate. The packaging containers and winding cores which do not bring about secondary pollution are thus obtd.</p> |
