Technology Sharing | How to Evaluate Biodegradability? What Are the Differences between GB, EN, and ASTM?
Biodegradable plastics refer to plastics that can be degraded by microorganisms such as bacteria, molds, and algae present in nature under certain conditions, ultimately breaking down into water, carbon dioxide, and other small molecules that enter the natural cycle. In practical applications, it is generally believed that biodegradation into water and carbon dioxide under the action of microorganisms is a more environmentally friendly degradation method.
