如今，塑料制品的弊端越來(lái)越被大家所認(rèn)識(shí)。世界資源是人們的熱門(mén)話題。節(jié)約資源的口號(hào)逐漸深入人心。因此，可降解顆粒產(chǎn)品的覺(jué)醒也是發(fā)展的需要。人們可以通過(guò)資源的循環(huán)利用，更好地實(shí)現(xiàn)環(huán)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.

如果每個(gè)人平均每天使用一種塑料制品，可能會(huì)有數(shù)億個(gè)垃圾，而這些垃圾需要幾百年才能完全降解。想想這是多么可怕的統(tǒng)計(jì)數(shù)據(jù)。反之，如果每個(gè)人都使用可降解顆粒，產(chǎn)生的廢物將在2-3年內(nèi)完全降解，轉(zhuǎn)化為二氧化碳、水和揮發(fā)物。你想看哪個(gè)？

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?

不過(guò)，也有質(zhì)疑的聲音。有人談?wù)摴芾戆咨廴締幔咳绾喂芾硭?？如何預(yù)防？面對(duì)諸多不卑不亢的質(zhì)疑，可降解塑料制品不僅可以在1-2年內(nèi)自行完全降解，而且還可以堆肥使用。

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說(shuō)是大有可為。也許有人對(duì)此有很大的懷疑，說(shuō)我們?cè)诖蹬＃科鋵?shí)原理很簡(jiǎn)單很簡(jiǎn)單，就是利用天然大分子（如淀粉、纖維素、甲殼類(lèi)）或農(nóng)副產(chǎn)品通過(guò)微生物發(fā)酵或合成可生物降解的大分子，如可降解顆粒產(chǎn)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，在經(jīng)濟(jì)環(huán)境中，毫無(wú)成本地談?wù)撊魏问虑槎紱](méi)有任何意義。目前的可降解塑料處于成本不占優(yōu)勢(shì)的尷尬境地。在談這個(gè)問(wèn)題之前，有必要先解釋一下可降解塑料與傳統(tǒng)塑料的區(qū)別。生活中常見(jiàn)的塑料主要有五類(lèi)，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）五類(lèi)塑料。這五種塑料的原料都是石油，是不可降解的塑料。而我們一般說(shuō)的無(wú)污染環(huán)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.

可降解顆粒廠家認(rèn)為一般指“生物降解塑料”，即全部或部分來(lái)源于生物質(zhì)的塑料。生物質(zhì)是生物來(lái)源的原材料，不包括嵌入地質(zhì)結(jié)構(gòu)或石化產(chǎn)品中的原材料?？杀晃⑸铮?xì)菌或真菌）分解成水、二氧化碳(CO2)和甲烷(CH4)等天然氣體和生物質(zhì)（如微生物數(shù)量增加）的塑料。當(dāng)然，生物降解性很大程度上取決于環(huán)境條件：溫度、微生物、氧氣和水的存在。

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.
