Biodegradable SEP environmental-friendly plastic

Abstract

The invention discloses biodegradable SEP environmental-friendly plastic, which comprises raw plastic grains and bacillus natto powder. The SEP environmental-friendly plastic has the advantages of natural biodegradability, low price, convenience, practicality, simple preparation, mass production by adopting the conventional mature process, recyclability, no toxicity when burned, low carbon and emission reduction.

Description

technical field [0001] The invention relates to a degradable plastic, in particular to a biodegradable SEP environment-friendly plastic. Background technique [0002] Disposable plastic packaging containers are lightweight, cheap, simple, convenient and practical, and are widely used in daily life. However, disposable plastic packaging containers are polymer plastic products made of polymer compounds such as polystyrene and ethylene, which are difficult to degrade after entering the natural environment. Excessive accumulation not only destroys the urban landscape, but also causes serious pollution to the natural environment, that is, Often referred to as white pollution. [0003] At present, the processing methods of traditional plastic waste are: [0004] (1) Recycling: This is the most ideal treatment method, but due to the wide variety of plastics, and the waste plastic products are mixed with various impurities, the use value is low, so it is currently impossible to ac...

AI Technical Summary

Problems solved by technology

[0004] (1) Recycling: This is the most ideal treatment method, but due to the wide variety of plastics, and the waste plastic products are mixed with various impurities, the use value is low, so it is currently impossible to achieve 100% complete recycling. use

[0005] (2) Burial: Polymer plastic waste is not easy to decompose and occupies a large amount of landfill space. The more waste there is in the city, the more difficult it is to obtain landfill space in the suburbs

[0006] (3) Incineration: Incineration of plastic waste products will emit black smoke when burned, pollute the air, and produce toxic gases such as hydrogen chloride, formaldehyde, and polychlorinated biphenyls, and due to incomplete combustion, black viscous colloids remain. Attached to the wall of the incinerator to block heat conduction and affect the service life of the incinerator

[0007] (4) Natural decomposition: Traditional plastic wastes are not easy to decompose and will not be melted for a hundred years. They are easy to pollute the natural ecology and cause more and more harm to the human living environment with the increase of garbage.

This is because (1) bioplastics are several times more expensive than traditional plastics; (2) the processing conditions for producing products with bioplastics are difficult, the production technology is immature, the loss is large, and the relative cost is much higher; (3) bioplastics cannot Effectively deal with the problem of waste recycling and reuse; (4) The finished product is not ideal, the product is not temperature-resistant, cannot be made very thin, but has only toughness but no rigidity, and the shelf life is unstable, causing another pollution of energy consumption and waste , unable to meet the basic conditions of use of the original plastic products; (4) Judging from the current consumption of disposable plastic products, if starch plastics are used as raw materials, a lot of food will be consumed
