Biodegradation generally refers to the decomposition of microorganisms. Microbial decomposition substances that exist in nature will not cause negative effects on the environment. The degree of degradation is called degradation index. Biodegradable materials refer to materials that can be completely decomposed by microorganisms (such as bacteria, fungi, algae, etc.) into low-molecular compounds under natural environmental conditions with appropriate and indicative deadlines.
Biodegradability is an important property of PBS polyester. At present, the main method for evaluating the biodegradability of plastics in the world is the composting method. Compost contains rich sources of microorganisms, which can macroscopically reflect the biodegradation of plastics in the natural environment to a certain extent. performance. GBPI Compost Degradation Tester can provide compost performance testing of most plastic products on the market.
