In the face of increasingly prominent environmental problems, self degradable daily necessities have attracted the attention of many people, including disposable tableware made of paper, wood, straw, corn starch and degradable plastics. However, it is found that the use of disposable chopsticks and other wooden tableware is limited due to the waste of resources, Other degradable tableware is not popular at present, but crystal tableware has been promoted with high recycling value. Let's analyze the current situation and Prospect of degradable tableware.

一次性可降解餐具目前主要面臨的問題有實(shí)用性不足和制造成本高等問題，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 faced by disposable degradable tableware are insufficient practicability and high manufacturing cost. As a container for food, the waterproof, acid and alkali resistance, oil salt and other properties of tableware are the basic requirements. However, the waterproof and strength of straw or corn starch are poor. In order to improve the performance, additives must be added, These additives should also meet the requirements of food grade, which increases the cost. Even so, they are still insufficient in waterproof and impermeability, and they will be damaged before they are used for too long.

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)境和生活帶來改變。

The cost of degradable plastics is higher. At present, it is still in the R & D and experimental 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 treat as disposable tableware. Therefore, at present, it is convenient to recycle and the same environmentally friendly disposable crystal meal has rationality, which is undeniable, Degradable materials will be gradually optimized and transformed in the future. When the problems such as use requirements and cost are solved, they will become the main trend of public daily necessities. We also expect these products to bring changes to the environment and life.
