What are biodegradable materials?

Biodegradable materials include biodegradable polymer materials such as carboxymethyl methyl cellulose, tapioca starch, paper, etc. Environmentally friendly degradable plastics also involve biodegradable plastics converted from microorganisms or obtained by analytical chemistry.Biodegradable plastics refer to the grading and/or stones, etc., and/or under unusual conditions such as retting or anaerobic digestion or in water-soluble cell cultures, caused by the ubiquitous microbial effects of naturedegrade, degrade into carbon dioxide or/and methane gas vapour gas, water and deashed sulphate of contained elements and their new biomass raw materials.It should be noted that each biodegradable material includes paper, etc., and biodegradable plastics are degraded according to the geographical environment conditions as far as possible. It is relatively slow; in addition, not every biodegradable material degrades rapidly under geographical environmental conditions. Therefore, for biodegradable materials, its geographical environmental conditions should be fully considered, and the structural characteristics of the materials themselves should be analyzed to distinguish whether they are biodegradable materials. How to judge whether a material is biodegradable or not, a series of inspection methods and standards have been implemented in the world and in China, which is a response to the problem of standardization.
