Abstract

The invention discloses a biodegradable material prepared from edible fungi residues and a preparation method of the biodegradable material. The biodegradable material is formed by extruding the following raw materials in percentages by weight: 65-100% of freshly harvested sporocarps and edible fungi residues without being polluted by infectious microbes, 0-15% of a fibrous material, 0-10% of an adhesive and 0-5% of a lubricant. Raw materials are simple and are easy to obtain, a preparation process is simple, a novel method for reusing the edible fungi residues is created, and the produced biodegradable material can be used for packing a heat-insulating layer, a ceiling and a decoration in a buffer material and a building material; and because production in a whole process is environment-friendly, the method is simple to operate, secondary pollutants are not produced, chemical agents such as formaldehyde are not used, and the biodegradable material as a decorative material or a building material does not have residual formaldehyde, and is safe. By the biodegradable material prepared from the edible fungi residues and the preparation method of the biodegradable material, waste materials can be turned into things of value, economic benefits can be brought to the edible fungi industry, agricultural and sideline products can be used as fiber sources, and a new purpose can be developed for the by-products; and moreover, the biodegradable material can replace a disposable foam material, and therefore, environmental pollution caused by the foam material is reduced.

Description

technical field [0001] The invention relates to the field of resource utilization and environmental protection of waste and agricultural by-products, in particular to a biodegradable material prepared from edible fungus residue and a preparation method thereof. Background technique [0002] In 2012, there were 788 edible fungus factory production enterprises nationwide. In 2012, the national edible fungus industrialized daily output reached 5,080 tons, an increase of nearly 60% from 3,188 tons in 2011, especially the output of Flammulina velutipes, which was 2,719 tons in 2012, more than double the 1,348 tons in 2011. Explosive growth. A large amount of edible fungus slag thus produced is a great available resource. Through research, it is found that for every 100kg of compost, after harvesting 100kg of fresh mushrooms, 60kg of edible fungus residue waste can be obtained. At present, the mushroom residue waste left after the fruiting bodies of edible fungi are harvested i...
