A PET plastic bottle. Soft drinks bottles made from the synthetic material PET, or polyethylene-terephthalate. Light weight and unbreakable, they are particularly suitable for carbonated beverages. Nowadays PET can be readily recycled, almost as easily as glass. The first step is to separate the materials according to type of plastic and colour. The bottles are carried on the conveyer belts past a series of detectors .They fly off the belt as if snatched by an invisible hand. X-ray eyes recognize all the items, register the different structures of the plastics. Expensive, fast computers can even compensate for errors in reading the paper labels. They can recognize a green PET bottle even when it is carrying a white label. A camera supplies the data for colour sorting. An extremely fast computer controls the air jets. And here we see the result of two hours of sorting procedure. Cleanly separated clear PET *** the labels in different colors. It would be perfectly possible to produce new PET bottles from these fragments. A light weight bottle like this has ecological advantages when it comes to transport. Glass is 20 times heavier.

　A PET plastic bottle. Soft drinks bottles made from the synthetic material PET, or polyethylene-terephthalate. Lightweight and unbreakable, they are particularly suitable for carbonated beverages. Nowadays PET can be readily recycled, almost as easily as glass. The first step is to separate the materials according to type of plastic and colour.

　　The bottles are carried on the conveyer belts past a series of detectors .They fly off the belt as if snatched by an invisible hand. X-ray eyes recognise all the items, register the different structures of the plastics. Expensive, fast computers can even compensate for errors in reading the paper labels. They can recognise a green PET bottle even when it is carrying a white label. A camera supplies the data for colour sorting. An extremely fast computer controls the air jets. And here we see the result of two hours of sorting procedure.

　　It would be perfectly possible to produce new PET bottles from these fragments. A lightweight bottle like this has ecological advantages when it comes to transport. Glass is 20 times heavier.



　软饮料的包装采用合成材料PET，也就是聚乙烯对苯二酸制成。轻便、不易碎，这种材料尤其适合碳酸类饮料的包装。现在PET可以像玻璃一样被有效循环再生。第一步就是对不同颜色，质地的瓶子进行分检。

　　传送带上的瓶子经过一系列检测。好像有一只无形的手将瓶子拽走。原来X光眼正逐个辨认，将结构不同的塑料分检。昂贵的计算机系统可以弥补X光眼的某些失误。 即使是贴有白色标签的绿色PET瓶子也逃不过计算机的监测。摄像机头提供色彩数据。一台速度极快的计算机负责控制抽干瓶中的空气。这就是两个小时分检的最终结果。

　　这些碎片可以成功地被重新制成PET瓶子。这种轻便的瓶子在运输时更显出其生态优势。玻璃是它的20倍重。
