Bio-based material concept: Distinguish between biodegradable material and biomaterial concept
Bio-based Materials and Biodegradable Materials are completely different concepts. Generally speaking, biodegradable macromolecular materials refer to macromolecular polymers that can be degraded under the action of microorganisms or under composting conditions. Bio-based materials emphasize the renewable origin of their biological sources, which can be either biodegradable polymers such as polylactic acid (PLA) or non-biodegradable polymers such as bio-based polyethylene; while biodegradable polymers The material emphasizes biodegradability, which can be either biodegradable polymers such as polylactic acid (PLA), or petroleum-based polymers (Petroleum-based Polymers) PBS and PBAT. Biodegradable plastics can be integrated into the circular economy through the idea of closing the Biological Cycle if they use biological raw materials and biodegrade under controlled composting conditions.
Bio-based Materials and Biomaterials are completely different concepts. Biomaterials refer to a class of materials used for the diagnosis, repair or function enhancement of combinations and organs in humans or animals, and can include organic materials, inorganic materials, metal materials, etc.
