1. Degradable natural material lunch box

以天然材料制成的一次性可降解餐盒又稱為生物全降解餐盒。生物全降解餐盒是一種比較的環(huán)保產(chǎn)品。它以淀粉為主要原料，加入一年生長期植物纖維粉和特殊的添加劑，經(jīng)過化學和物理方法處理制成生物全降解快餐盒。

The disposable degradable lunch box made of natural materials is also called biological fully degradable lunch box. Biodegradable lunch box is an advanced environmental protection product. It takes starch as the main raw material, adds one-year plant fiber powder and special additives, and is processed by chemical and physical methods to make a biodegradable fast food box.

由于淀粉是一種可生物降解天然高分子，在微生物的作用下分解為葡萄糖，分解為水和二氧化碳。此外，與其共混的材料也是全降解材料，因此可以說它對環(huán)境沒有任何影響。生產(chǎn)原料淀粉的主要來源，可以是玉米、土豆、紅薯、木薯等一年生長期植物。自然，生物全降解餐盒也并不是十全十美，例如，生產(chǎn)原料大部分是糧食作物，且有防霉變等問題尚待解決。

As starch is a biodegradable natural polymer, it is decomposed into glucose, water and carbon dioxide under the action of microorganisms. In addition, the material blended with it is also a fully degradable material, so it can be said that it has no impact on the environment. The main source of raw starch can be plants in one-year growth period such as corn, potato, sweet potato and cassava. Naturally, biodegradable lunch boxes are not perfect. For example, most of the production raw materials are food crops, and problems such as mildew prevention have yet to be solved.

2、可降解塑料餐盒

2. Degradable plastic lunch box

此類一次性餐盒的制造原料是可降解塑料，所謂可降解塑料就是在塑料的生產(chǎn)過程中加入一定量的添加劑，如光敏劑、淀粉等原料。這樣，可降解塑料制品在使用完，并廢棄在大自然中暴露三個月后，可由完整的形狀分解成碎片，因而少在視覺上改善了環(huán)境

The raw material of this kind of disposable lunch box is degradable plastic. The so-called degradable plastic is to add a certain amount of additives in the production process of plastic, such as photosensitizer, starch and other raw materials. In this way, the degradable plastic products can be decomposed into fragments from the complete shape after being used, discarded and exposed in nature for three months, thus improving the environment at least visually

但這項技術的缺陷是，這些碎片不能繼續(xù)降解，只不過是由大片變成小片塑料，不能從根本上勝任白色污染的任務。

However, the biggest defect of this technology is that these fragments can not continue to degrade. They just change from large pieces to small pieces of plastic, which is not fundamentally competent for the task of eliminating white pollution.
