    摘要: A method of recycling polymers and other plastics comprises: (A) grinding recycled PET bottles (or other suitable recycled polymer) into a group of flakes; (B) washing the flakes; (C) identifying and removing impurities, including impure flakes, from the group of flakes; (D) passing the group of flakes through an MRS extruder while maintaining the pressure within the MRS portion of the MRS extruder below about 5 millibars; (E) passing the resulting polymer melt through at least one filter having a micron rating of less than about 50 microns; and (F) preparing the polymer melt for recycling into a new product. In various embodiments, the above process may be utilized in the recycling of, for example, polytrimethylene terephthalate (PTT), polypropylene, polyvinyl chloride (PVC), high-density polyethylene (HDPE), polystyrene (PS), expanded polystyrene (EPS), or any other suitable polymer or plastic
