Material: Polylactic acid (PLA)

Material Description: Polylactic acid (PLA) is a new type of biodegradable material made from starch raw materials derived from renewable plant resources such as corn. Starch raw materials are saccharified to obtain glucose, which is then fermented with glucose and certain bacterial strains to produce high-purity lactic acid. Polylactic acid with a certain molecular weight is then synthesized through chemical synthesis methods. It has good biodegradability and can be completely degraded by microorganisms in nature after use, ultimately producing carbon dioxide and water without polluting the environment. This is very beneficial for protecting the environment and is recognized as an environmentally friendly material. The treatment method for ordinary plastics is still incineration and cremation, causing a large amount of greenhouse gases to be emitted into the air, while polylactic acid plastics are buried in the soil and degraded, producing carbon dioxide that directly enters the soil organic matter or is absorbed by plants, and will not be discharged into the air, thus not causing the
