如今，塑料制品的弊端越来越被大家所认识。世界资源是人们的热门话题。节约资源的口号逐渐深入人心。因此，可降解颗粒产品的觉醒也是发展的需要。人们可以通过资源的循环利用，更好地实现环保。

Nowadays, the disadvantages of plastic products are more and more recognized by everyone. World resources are a hot topic for people. The slogan of saving resources has gradually taken root in the hearts of the people. Therefore, the awakening of degradable granule products is also the need of development. People can better realize environmental protection and energy conservation through the recycling of resources.

如果每个人平均每天使用一种塑料制品，可能会有数亿个垃圾，而这些垃圾需要几百年才能完全降解。想想这是多么可怕的统计数据。反之，如果每个人都使用可降解颗粒，产生的废物将在2-3年内完全降解，转化为二氧化碳、水和挥发物。你想看哪个？

If everyone uses one kind of plastic product on average every day, there may be hundreds of millions of garbage, which will take hundreds of years to completely degrade. Think about what terrible statistics this is. On the contrary, if everyone uses degradable particles, the waste generated will be completely degraded and converted into carbon dioxide, water and volatile matter within 2-3 years. Which would you like to see?

不过，也有质疑的声音。有人谈论管理白色污染吗？如何管理它？如何预防？面对诸多不卑不亢的质疑，可降解塑料制品不仅可以在1-2年内自行完全降解，而且还可以堆肥使用。

However, there are also voices of doubt. Does anyone talk about managing white pollution? How to manage it? How to prevent? In the face of many unashamed questions, degradable plastic products can not only be completely degraded within 1-2 years, but also be composted.

可降解塑料制品可以说是大有可为。也许有人对此有很大的怀疑，说我们在吹牛？其实原理很简单很简单，就是利用天然大分子（如淀粉、纤维素、甲壳类）或农副产品通过微生物发酵或合成可生物降解的大分子，如可降解颗粒产品。

Degradable plastic products are promising. Maybe some people have great doubts about this, saying that we are bragging? In fact, the principle is very simple. It is to use natural macromolecules (such as starch, cellulose, crustaceans) or agricultural and sideline products to ferment or synthesize biodegradable macromolecules, such as biodegradable granular products.

此外，在经济环境中，毫无成本地谈论任何事情都没有任何意义。目前的可降解塑料处于成本不占优势的尴尬境地。在谈这个问题之前，有必要先解释一下可降解塑料与传统塑料的区别。生活中常见的塑料主要有五类，即聚乙烯（PE）、聚丙烯（PP）、聚氯乙烯（PVC）、聚苯乙烯（PS）和丙烯腈-丁二烯-苯乙烯共聚物（ABS）五类塑料。这五种塑料的原料都是石油，是不可降解的塑料。而我们一般说的无污染环保材料。

In addition, in the economic environment, there is no point in talking about anything without cost. At present, degradable plastics are in an awkward situation where the cost is not dominant. Before discussing this issue, it is necessary to explain the difference between degradable plastics and traditional plastics. There are five kinds of plastics commonly used in daily life, namely polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and acrylonitrile butadiene styrene copolymer (ABS). The raw materials of these five kinds of plastics are petroleum, which are non degradable plastics. And what we generally call pollution-free environmental protection materials.

可降解颗粒厂家认为一般指“生物降解塑料”，即全部或部分来源于生物质的塑料。生物质是生物来源的原材料，不包括嵌入地质结构或石化产品中的原材料。可被微生物（细菌或真菌）分解成水、二氧化碳(CO2)和甲烷(CH4)等天然气体和生物质（如微生物数量增加）的塑料。当然，生物降解性很大程度上取决于环境条件：温度、微生物、氧气和水的存在。

Manufacturers of degradable particles generally refer to "biodegradable plastics", that is, plastics wholly or partially derived from biomass. Biomass is a raw material from biological sources, excluding raw materials embedded in geological structures or petrochemical products. Plastics that can be decomposed by microorganisms (bacteria or fungi) into natural gases such as water, carbon dioxide (CO2) and methane (CH4) and biomass (such as the increase in the number of microorganisms). Of course, biodegradability largely depends on environmental conditions: temperature, presence of microorganisms, oxygen and water.
