四大类环保一次性餐盒你知道哪些？

When purchasing disposable lunch boxes and drinking utensils, customers can also understand the quality assurance of the products by looking at the QS mark, production license number, manufacturer, production address and other information on the packaging box. When buying, try to choose the disposable lunch box tableware with smooth surface, uniform color, no pattern, colorless and transparent, and try not to choose the product that is too soft. Next, let's introduce four types of environmental friendly disposable lunch boxes.

，淀粉类：

First, starch:

不利因素：防霉技术尚未解决，成本过高，即使技术过关了，由于我国是粮食短缺国家，也很难形成市场。

Adverse factors: the anti mildew technology has not been solved, and the cost is too high. Even if the technology passes, it is difficult to form a market because China is a country with food shortage.

第二，可降解塑料：

Second, degradable plastics:

缺陷：该餐具只在塑料中添加光敏剂和淀粉，添加物部分可降解，塑料部分仍不可降解，因此不属于真正意义上的绿色环保产品，不宜推广。

Defect: the tableware only adds photosensitizer and starch to the plastic. The additive part is degradable, and the plastic part is still non degradable. Therefore, it is not a real green environmental protection product and should not be popularized.

第三、纸浆类别：

Third, pulp category:

不足之处：A、一个纸模餐盒重25克，成本0.35元，日产4万只餐盒所需一吨纸浆，相当于砍掉一吨计重的树木，每年以300天工作日计算，砍掉近300立方米树木，对本是森林贫瘠的我国来说，这无疑是雪上加霜，并由此带来的水土流失、土地荒漠化等问题更加难以想象。B、加上价格偏高，消费者很难接受。C、不宜与放汤同饮，韧性不足。

Disadvantages: a. a paper mold lunch box weighs 25g and costs 0.35 yuan. A ton of pulp is required for a daily output of 40000 lunch boxes, which is equivalent to cutting down a ton of trees. Based on 300 working days every year, nearly 300 cubic meters of trees are cut down. For China, which is originally a barren forest, this is undoubtedly adding to the snow, resulting in soil erosion Land desertification and other issues are even more unimaginable. B. Coupled with the high price, it is difficult for consumers to accept. C. It is not suitable to drink with soup, and the toughness is insufficient.

第四，植物纤维类：

Fourth, plant fibers:

好处：一是可再生资源来源，二是形成过程中及废弃后不污染环境，三是再生产过程节约资源。以一年生草本植物秸秆纤维为原料制作植物纤维一次性餐具。

Advantages: first, the source of renewable resources; second, it does not pollute the environment during the formation process and after abandonment; third, it saves resources in the reproduction process. The disposable tableware of plant fiber was made with annual herb straw fiber as raw material.
