Starch raw materials are saccharified to obtain glucose, then glucose and certain strains are fermented to produce high purity lactic acid, and polylactic acid with certain molecular weight is synthesized by chemical synthesis method. It has good biodegradability, can be completely degraded by microorganisms in nature under specific conditions after use, and finally generates carbon dioxide and water without polluting the environment, which is very beneficial to environmental protection and is recognized as an environment-friendly material.
