Because of the different varieties and chemical structures of biodegradable materials, the degradation under different conditions is different, and its degradation requires certain external environmental conditions, and cannot be degraded in any environment. Its degradation conditions and environments can be various, for example, in compost, soil, river water, seawater and other environments, degradation can occur under suitable conditions of temperature, humidity and microorganisms.
As a degradable material, in fact, the degradation time and natural conditions as well as the structure and formulation of the degraded material have a certain relationship. If the natural conditions do not give some suitable conditions for the growth or life activities of microorganisms, the degradation of biodegradable materials will also be relatively slow. For example, when we are on the mountain, we can see that some branches, wood or paper on the sandy soil have not been degraded by the environment for a long time. This is the reason.
