原标题：【产业】三分钟看完塑料回收再生全过程。
小编带你走进不算神秘却也不轻易见得到的塑料回收流水线。
【演示地址：点击这里 】
所有使用过的塑料材料都由当地组织收集，并运输到全国各地的分拣设施。塑料回收工厂将负责按照不同的产品类别，除去那些不可加工利用的废料，将所有的塑料包装材料分类。
膜，聚烯烃和混合塑料袋等材料将通过抽吸系统被捕获。相反，液体容器和其他材料是经过一系列的程序化的光学识别系统进行分类。
PET通过高压空气射流将包装材料整理，同时，扫描系统将PET按颜色归类，例如蓝色或是混合色或是透明色。
HDPE材料的容器不需要通过高压空气射流压缩，而是容器专用输送带，经过一系列精确的自动和手动控制之后，被选择的包装材料在机器中通过远程选项运送到回收公司。
不同的聚合物在回收过程中，包括一些类似的阶段，都将在不同的专用机器中进行。例如，PET需要先清洗，然后将包装放在专用的清洗池中，用热水和蒸汽清洗，以除去所有的表面杂质和缺陷。
之后，一个装有刀片的磨碎机将瓶子破碎成很小的块，也就是所谓的“薄片”。这些薄片在一系列装有不同洗涤剂的清洗容器中再次洗涤后，才会完全清洁干净。
最后他们将进行离心和干燥，运用强大的抽吸系统，去除残余的灰尘和水分，通过这个程序以后，回收聚酯过程基本结束了。对于HDPE和混合聚烯烃，它们还需一个步骤然后转化为颗粒 。
这些材料最后看起来是很小的，首先，先对这些材料加温直到融点，同时，将它们堆积在一起，用刀片割成类似面条的长条。
薄片和颗粒将被精确控制和测试，并确保它们质量符合标准要求。最后，它们将被装在大袋中，交付给企业用于生产不同的品牌的产品。
这些材料来自不同的地区，再生后也将运往不同的地区，塑料再生循环就这样生生不息，永不结束，never end。

All used plastic materials are collected by the local councils and delivered to the sorting facilities which are located around the entire country.
All of these plants were tasked with sorting all the packaging into different product categories removing all the waste materials. films, polyolefine and mixed plastic bags were captured through an aspiration system.
Liquid containers and other materials instead go through a series of optical readers which are programmed to recognize materials and sort the packaging into pet dashing them with a high pressured jet of air.
The same scan system or some exceed possible to divide PET into three different color categories like blue, mixed and transparent.
The containers in HDPE which are not hit with jet of air fall instead on to the dedicated conveyor belt.After a series of accurate automated and manual controls the different categories of selected packaging exit the machinery so that corupler deliver them to the recycling companies through remote options.
The recycling process for the different polymers includes some similar phases but they are carried out by different dedicated machines.
The PET for example needs to be prewashed first,the packaging is placed in a dedicated drum and washed with hot water and steam to remove all the surface imperfections.
Afterwards a mill equipped with blades will juices the bottles into very small pieces which is also called “Flakes”. The flakes are washed once again with special detergents in a series of tanks from where they emerged totally clean.
Finally they are centrifuged and dried, thanks to powerful aspiration system which removes the residual dust and moisture. The recycling PET process is now over.
Well in the case of HDPE and mixed polyolefine , it needs a further step before the final transformation into granules. These materials are end up looking like small , firstly they will be wormed up to their fusion point and simultaneously pushed in to a mound which create a longer strips similar to spaghetti cut preciously by a blade.
Flakes and granules are accurately controlled to test their quality and ensure their incompliance with required standards. And afterwards they are collected in large bags and delivered to the companies which were use them to produce brand new objects may be very different from the one they came from, because the plastic resources are in fact never ending.
