Polyethylene (PE) recycle
The stpes to recycle are generally like the following:
First PE waste is sorted and cleaned to remove any contaminants such as dirt, labels, or other plastics.
Shredding: The clean PE film is then shredded into small pieces to increase its surface area and facilitate melting.
Extrusion: The shredded PE film is fed into the extruder, a machine that melts the plastic using heat and pressure. Inside the extruder, the plastic is heated to a specific temperature, typically above its melting point, and forced through a die to create a continuous stream of molten plastic.
Pelletizing: As the molten plastic exits the extruder, it is cut into uniform pellets by a pelletizer. These pellets can then be cooled and solidified for storage or further processing.
Quality Control: Throughout the extrusion process, quality control measures are in place to ensure the output meets the desired specifications. This may include monitoring temperature, pressure, and pellet size.
Reuse or Resale: The recycled PE pellets can be used as raw material in various applications, including the manufacturing of new plastic products or packaging. Alternatively, they may be sold to other companies for use in their production processes.
By using an extruder in the recycling process, PE film waste can be efficiently transformed into reusable pellets, contributing to the reduction of plastic waste and the promotion of a circular economy.
