Biodegradation: The material is continuously discharged from the body during the process of tissue growth in the organism through dissolution, enzymatic digestion, cellular phagocytosis, etc. The repaired tissue completely replaces the implanted material, and the material does not have a residual nature in the body.
Biodegradable materials: Materials that can be completely decomposed into low molecular compounds by microorganisms (such as bacteria, fungi, algae) under appropriate and limited time natural conditions.
Degradation index: the degree of degradation of the material.
Composting method: The principle is to use microorganisms to metabolize and decompose organic materials in waste, which can be harmlessly treated at high temperature and produce organic fertilizer. It is the main method to evaluate the biodegradation performance of plastics internationally.
Testing standard:
Chinese standard: GB/T
：ISO ;EN13432:2000
American Standard：ASTM D6400
