Description

Method for manufacturing fully biodegradable tableware and production equipment thereof

Technical Field

The invention relates to the technical field of biodegradable tableware, in particular to a method for manufacturing fully biodegradable tableware and production equipment thereof.

Background

Along with the development of society, people also change in the material use of articles, and people use a large amount of disposable articles corresponding to the current fast-paced society. For example, egg shake-proof holders made of disposable packing and filling materials, inverted flower pots, cup mats and the like are used; disposable food and drink utensils such as cup, bowl, plate, lunch box, spoon, short-term moisture-proof fruit and vegetable tray, etc. However, the disposable articles made of the plastic materials cannot be completely self-decomposed, and cause pollution to the environment.

With the increasing severity of the problems brought by the use of plastic products, various countries and governments make positive countermeasures for the problems, and China has completely prohibited the use of disposable foamed plastic tableware in 2000. Related plastic limit laws are also issued in 2020 across the country, and the research, development and popularization of full-biodegradable plastic substitutes are promoted while the use of disposable non-degradable plastic products is limited.

In order to meet the market demand nationwide, a series of substitute products have been developed and produced in China, and the main varieties are as follows: the bio-resin products, the paper pulp products, the starch-based degradable plastic products, the plant straw products and the like have great progress in the aspect of environmental protection performance. However, they still suffer from significant drawbacks. For example, the biological resin polylactic acid can be completely biodegraded, but about 4 tons of corn starch are needed for extracting 1 ton of polylactic acid, so that the production cost of the product is high, the product price is high, and the product is difficult to popularize. The production of the paper pulp tableware consumes a large amount of forest resources, and COD (chemical oxygen demand) emission problems are generated in the pulping process, so that the paper pulp tableware is harmful to the ecological environment.

The starch-based degradable plastic tableware is actually a product prepared by mixing polypropylene, polyethylene and other plastics with starch, and after the starch-based degradable plastic tableware is discarded, only the starch component in the starch-based degradable plastic tableware is biodegradable, and the plastic component is cracked into fragments and cannot be degraded, so that the problem of more difficult treatment is caused, and the environment is still polluted. The tableware made of plant straws has rich resources and low cost, but the waste liquid COD (chemical oxygen demand) discharge problem is also generated in the processes of extracting fiber from the straws and pulping, thereby influencing the ecological environment.

Therefore, how to manufacture a plastic tableware substitute product which has no pollution harm to the ecological environment, is safe and nontoxic to people, and has comprehensive advantages of rich raw materials, low cost, good use performance and the like is the current technical difficulty; therefore, the manufacturing method and the production equipment of the fully biodegradable tableware are provided for solving the problems.
