当我们走进超市,里面的产品百分之80是塑料包装的产品,这种塑料包装使用量巨大,但是降解难度大,给环境带来了严重的负担。

When we enter the supermarket, 80% of the products in it are plastic packaging products. This kind of plastic packaging is used in a large amount, but it is difficult to degrade, which brings a serious burden to the environment.
海洋垃圾质量庞大
The quality of marine garbage is huge
海洋已经沦为垃圾场,某些海域漂浮着几十万甚至数百万吨的塑料垃圾,或许还有更多的垃圾沉积到了未知区域。我们肉眼可见的垃圾只是其中很小一部分。全球每年大约会生产30亿吨聚合材料,这些聚合材料广泛用到了各个领域。保守估计,其中大约千分之一的聚合材料,更终会以塑料垃圾的形式流向大海,年复一年,在大海中集聚起来的塑料垃圾总量已经相当庞大。
The ocean has become a garbage dump, with hundreds of thousands or even millions of tons of plastic garbage floating in some sea areas, and perhaps more garbage has been deposited in unknown areas. The garbage we can see with our naked eyes is only a small part of it. About 3 billion tons of polymer materials are produced in the world every year, which are widely used in various fields. It is conservatively estimated that about one thousandth of the polymer materials will eventually flow to the sea in the form of plastic waste. Year after year, the total amount of plastic waste accumulated in the sea is quite large.
可降解颗粒
入侵食物链
Invading the food chain
塑料进入海水中,碎屑容易和浮游生物混合在一起,体型较大的生物会将塑料颗粒连同浮游生物一起吃掉,但是微塑料颗粒难以消化,都会堆积在海洋生物的体内,还有可能随着食物链进入人体内。
When plastic enters the sea water, debris is easy to mix with plankton. Larger organisms will eat plastic particles together with plankton. However, micro plastic particles are difficult to digest and eventually accumulate in the body of marine organisms, and may enter the human body along with the food chain.
塑料在生物体内会产生多种影响——大多是不良影响,这些塑料通常会释放出一些可以影响激素分泌的化合物 ,进而影响动物行为。
Plastics have a variety of effects - mostly adverse effects - in organisms. They usually release compounds that affect hormone secretion and thus affect animal behavior.
可降解塑料包装袋带来解决之道
Biodegradable plastic bags bring solutions
可降解塑料包装袋就是使用全生物可降解可塑性颗粒材料所制作的包装袋,可以降解,用于产品或食品包装。与普通塑料包装袋的区别就在于,可降解塑料包装袋在丢弃之后,可以在自然条件或堆肥的特定条件下,由自然界存在的微生物作用引起降解,更终转化成二氧化碳和水,而普通的塑料包装袋不可降解,或者需要五百年左右才能降解,对环境危害大。
Biodegradable plastic packaging bag is made of biodegradable plastic granular materials, which can be degraded and used for product or food packaging. The difference between degradable plastic bags and ordinary plastic bags is that, after being discarded, degradable plastic bags can be degraded by microorganisms existing in nature and finally converted into carbon dioxide and water under the specific conditions of natural conditions or composting. However, ordinary plastic bags are not biodegradable, or it takes about 500 years to degrade, which is harmful to the environment.
可降解产品的发展现在已是大势所趋,传统塑料产品终将被可降解产品替代。
The development of degradable products is the general trend, and the traditional plastic products will be replaced by degradable products.
