Faced with increasingly prominent environmental problems, self-degradable daily necessities have attracted a lot of attention. Disposable tableware including paper, wood, straw, corn starch, and degradable plastics have also attracted public interest. However, people It is found that disposable chopsticks and other wooden tableware are restricted due to the waste of resources, while other degradable tableware is not popularized at present. Instead, crystal tableware has been promoted with high recycling value. Let’s analyze it together. Current status and prospects of degradable tableware.
The main problems faced by disposable degradable tableware are insufficient practicability and high manufacturing cost. As food containers, the water resistance, acid and alkali resistance, and oil and salt properties of the tableware are the basic requirements, but whether it is straw or corn starch It has poor water resistance and insufficient strength. In order to improve performance, additives must be added. These additives must meet food-grade requirements and increase costs. Even so, they are still insufficient in issues such as waterproof and anti-permeability, and usually cannot be used too much. It will be damaged for a long time.
The cost of degradable plastics is higher, and it is still in the research and development test stage. Its degradation conditions are relatively harsh. For example, photosensitive degradation needs to be carried out in the sun. It is inconvenient to use and handle as disposable tableware. Therefore, at present, The disposable crystal meal that is easy to recycle and the same environmental protection is reasonable. It is undeniable that degradable materials will gradually be optimized in the future. When problems such as use requirements and cost are solved, it will become the main trend of popular daily necessities. It is also expected that these products can bring changes to the environment and life.
