Abstract
A method of recycling a PET-containing material comprises: (1) providing a polymer crystallizer comprising at least one heating element, and at least one blower; (2) providing an MRS extruder having an MRS section comprising a plurality of satellite screws; (3) providing a vacuum pump in fluid communication with the MRS section; (4) grinding and washing the PET-containing material; (5) heating the PET-containing material in the crystallizer to at least partially dry the PET-containing material; (6) shearing the PET-containing material in the MRS extruder to produce a PET-containing melt; (7) increasing a surface area of the PET-containing melt by distributing the PET-containing melt across a plurality of satellite screws in the MRS extruder; (8) drawing off vapors from the PET-containing melt by reducing the pressure in the MRS section with the vacuum pump; (9) collating the PET-containing melt in the MRS extruder; and (10) extruding a recycled PET-containing material.
