Biodegradable materials include biodegradable natural polymer materials such as methyl cellulose, cassava starch, paper, etc., and biodegradable plastics obtained by biological generation or organic synthesis, etc.

Biodegradable plastics are those that are degraded by natural microorganisms under natural conditions such as soil and/or sand, and/or under special conditions such as compost or anaerobic digestion, or in water-soluble cell cultures. And finally completely degrades into carbon dioxide (CO2) or/and methane gas (CH4), water (H2O) and the acidic carbonates containing the elements and their new biomass (such as microbial dead bodies, etc.).
 

It should be noted that each biodegradable material, including paper, must be degraded under certain natural environment conditions. If there is no degradation condition, especially under the daily living conditions of microorganisms, the degradation will be relatively slow. At the same time, not every biodegradable material degrades quickly under all natural environmental conditions. Therefore, when considering biodegradable materials, we should consider their natural environmental conditions and analyze and judge whether they are biodegradable materials by integrating their own structure. How to judge whether a material is biodegradable or not, a series of standards of inspection methods have been promulgated internationally and in China, which are responded in the normative problem.
 

What are the ingredients of biodegradable materials? Bring this question with you to answer your questions. Degradable plastic refers to a type of plastic, whose products have the ability to meet the requirements of the application of a variety of properties, storage life will not change, and after application can be reduced in geographical environmental standards to the natural environment of the chemical substances. Based on the selection of raw materials and manufacturing processes to upgrade manufacturing, biodegradable plastics can be slowly transformed into fragments by the combined effects of sun, precipitation and microorganisms for days or months, and eventually all dissolved. Biodegradable materials generally fall into four categories: photodegradable plastics, biodegradable plastics, photobiodegradable plastics and water-degradable plastics. It is seen as an alternative to traditional single-use plastics in the context of "no plastics" and environmental awareness. According to the characteristics of biodegradable plastics, the downstream applications include agriculture and animal husbandry, forestry and fruit industry and aquaculture industry, packaging industry, sports and sports articles, daily necessities and other industries.
