plastic waste




Plastics are so important that we can not live without it. It starts to be found in850 in English. More than 100 years, it is everywhere around us in the world. From the packages for foods and the daily necessities storage to the chemicals and drugs packing, we use it everywhere. It is the most accessible materials in our daily life. We notice the advantage of the plastics that with good isolation, and tough, cheap and good stability. Since it brings us such convenience, but it also cause much environmental problems.


  1. All kinds of plastics is hard to degradate naturally. It cause the solid wastes increase on the earth. Largely impact the big cities land usage also will poison the land.
  2. The ocean ecosystem will be impacted. If the plastics go to the ocean, it will make ocean animals take it as food by mistake and cause the poison and asphyxia,
  3. Burning the plastics will cause the atmosphere pollution.


We have to recycle the plastics by the resin identification code. Different plastics characteristics are different. And usually the waste recycling we collect those plastics together. It is a tough task for us to sort the plastics. Generally we have to sort plastics by manual and by intelligent machines. After that it will be crushed and then wash and then dry. After drying it can be pelletized for the next production,such as the HDPE bottles hot wash and pelletizing machine. The washed dry material can be directly used for production usage, like hot washed PET flakes to POY fiber.
