PLA is not plastic. It is derived from nature. Starch is extracted from plants such as corn and cassava and fermented by microorganisms to produce lactic acid. Lactic acid undergoes an advanced polymerization process to produce a 100% green and safe new polymer material called polylactic acid (PLA). Products made from this material are healthy and safe, non-toxic and odorless, and have no harm to the human body. In addition, if the product is discarded under composting conditions, it can be completely decomposed by microorganisms, eventually generating carbon dioxide and water, and returning to nature. The environment does not cause any pollution, so PLA is recognized as a â??green materialâ?? for low-carbon environmental protection and sustainable development in the 21st century.
