In the face of increasingly prominent environmental problems, self degradable daily necessities have attracted many people's attention, including disposable tableware made of paper, wood, straw, corn starch and degradable plastics, which has also aroused public interest. However, it is found that disposable chopsticks and other wooden tableware are limited to use because of the waste of resources, while other degradable tableware is limited Crystal tableware was not popularized before, but was promoted with high recycling value. Let's analyze the current situation and Prospect of disposable environmental protection tableware.

一次性可降解餐具目前主要面臨的問(wèn)題有實(shí)用性不足和制造成本高等問(wèn)題，作為食品盛裝的容器，餐具的防水、耐酸堿和油鹽等性能是基本要求，然而無(wú)論是秸稈還是玉米淀粉本身防水性比較差，強(qiáng)度也不足，為了提高性能必須添加助劑，這些助劑也要符合食品級(jí)要求，增加了成本，并且即使這樣，在防水抗?jié)B透等問(wèn)題上還是不足，通常使用不了太長(zhǎng)時(shí)間就會(huì)損壞。

At present, the main problems of disposable degradable tableware are lack of practicability and high manufacturing cost. As a food container, tableware's waterproof, acid and alkali resistance, oil and salt resistance are the basic requirements. However, both straw and corn starch have poor water resistance and insufficient strength. In order to improve the performance, additives must be added, and these additives should also meet the food grade requirements Even if the cost is too long, it will not increase the use time.
                                               

而可降解塑料的成本更高，目前還處于研發(fā)試驗(yàn)階段，它的降解條件比較苛刻，如光敏降解需要在陽(yáng)光下進(jìn)行，作為一次性餐具使用和處理都有一定的不便，所以，當(dāng)前來(lái)看便于回收的，同樣環(huán)保的一次性水晶餐具有存在的合理性，不可否認(rèn)，可降解材料在以后會(huì)逐漸得到優(yōu)化改造，當(dāng)解決使用要求和成本等問(wèn)題后，會(huì)成為大眾日用品的主要趨勢(shì)，我們也期待這些產(chǎn)品能為環(huán)境和生活帶來(lái)改變。

The cost of degradable plastic is higher, and it is still in the research and development stage. Its degradation conditions are relatively harsh. For example, photosensitive degradation needs to be carried out in the sun. As a disposable tableware, it is inconvenient to use and deal with. Therefore, at present, the disposable crystal meal which is easy to recycle and also environmental protection is reasonable. It can't be denied that degradable materials will be used in the future Gradually get optimization and transformation, when the use requirements and cost problems are solved, it will become the main trend of public daily necessities. We also expect these products to bring changes to the environment and life.
