Biodegradation formation article and its mfg. method

Abstract

A biodegradation formation article, in which non-fibrous components originating from natural organic substances (animal excretion, food and the like) are dispersed between vegetable fiber (wood fiber, linter fiber, bast fiber, stem fiber) to obtain moldings. The moldings are increased in its wet tensile strength by treatment with heat. The relation of the density of the moldings (D) with the wet tensile strength (S) is defined by the following formula (1): S>=3.8times D-1.2... (1) (wherein S is wet tensile strength is MPa; D is density of the moldings in g / cm<3>). The moldings show excellent biodegradability as well as wet tensile strength.

Description

technical field [0001] The present invention relates to a biodegradable biodegradable material (agricultural resource material, horticultural resource material, greening resource material, etc.) moldings. More specifically, it relates to an organic material that can effectively utilize animal excrement (poultry excrement, etc.), food waste (fresh garbage, etc.), discarded plant fiber components (waste paper, etc.), etc. A biodegradable molded article of an environmental burden and a manufacturing method thereof. Background technique [0002] With the development of the chemical industry ushered in the birth of plastics. Because of its advantages of being light, strong, and not rotten, it is widely used in various fields to manufacture various products. Of course, the use of plastics is also prevalent in the manufacture of molded objects (film-like covering materials, pots, seedling pots, plant growing containers, etc.) for agriculture, gardening, and landscaping.
