摘要： A method of manufacturing PET nurdles comprises the steps of grinding a plurality of recycled PET bottles into a group of polymer flakes and of washing the group of polymer flakes to remove at least a portion of one or more contaminants from a surface of the flakes. The group of flakes comprises a first plurality of flakes that consist essentially of PET and a second plurality of flakes that do not consist essentially of PET. The method comprises the steps of scanning the washed group of flakes to identify the second plurality of flakes, and of separating the second plurality of flakes from the first plurality of flakes. The second plurality of flakes is molten to produce a polymer melt; via providing an extruder that extrudes material in a plurality of different extrusion streams; via reducing a pressure within the extruder to between about 0 millibars and about 25 millibars; while maintaining the pressure within the extruder between about 0 millibars and about 25 millibars, passing the polymer melt through the extruder so that the polymer melt is divided into a plurality of extrusion streams, each having a pressure between about 0 millibars and about 25 millibars. After passing the polymer melt through the extruder, the polymer melt is filtered through at least one filter. The polymer melt is then pelletized to form a plurality of PET nurdles.

摘要： Method for manufacturing PET pellets, said method comprising: preparing flakes of PET polymer from post-consumer bottles; passing the flakes through a suitable extruder (400) that melts the flakes and purifies the resulting PET polymer melt; and pelletizing the molten PET polymer; wherein said pelletizing includes passing strands of said molten PET polymer through a suitable cooling bath to at least partially harden the polymer melt; and converting the polymer strands that have been cooled and at least partially solidified into pellets by cutting.
