At present, using biodegradable tableware instead of plastic tableware may be a small step, but it will certainly have an effective impact on our environment. Degradable tableware is derived from renewable plants and other natural substances, such as PLA polylactic acid, sugarcane pulp, corn starch, fallen leaves and recycled paper. Compostable tableware is a new era of material technology progress, which will cultivate rather than damage the environment. In order to obtain a healthy environment and keep our planet green, it is very important to completely stop using plastics and switch to completely natural and environmentally friendly biodegradable tableware. There are many benefits of using compostable meals because it provides excellent environmental protection solutions. These tableware are not only natural, but also combine the flexibility and convenience of plastic food containers or other tableware, as well as the environmental protection advantages of complete biodegradation. Both our health and the deteriorating state of the earth are interrelated. The important thing about using biodegradable tableware is that they have a positive impact on the environment. Changing to environmentally friendly spoons, forks, plates and glasses only means that there is less plastic on our planet. Biodegradable plate is made of polyester polymer polymerized with lactic acid as the main raw material, which is a new type of biodegradable material. This makes these PLA polylactic acid products 100% biodegradable and compostable. After use, it can be completely degraded by microorganisms in nature to generate carbon dioxide and water without polluting the environment, which is very beneficial to environmental protection and is recognized as environmentally friendly materials. The treatment method of ordinary plastics is still burning and cremation, which causes a large amount of greenhouse gases to be discharged into the air, while polylactic acid plastics are buried in the soil for degradation, and the carbon dioxide generated directly enters the soil organic matter or is absorbed by plants, which will not be discharged into the air and will not cause greenhouse effect.
