Abstract: A method for forming additive-containing reclaimed polyester can include: providing a feed of recycled polyester; providing a feed of polyester precursors; depolymerizing the recycled polyester to obtain depolymerized polyester monomers; polymerizing the depolymerized polyester monomers with the polyester precursors to form a reclaimed polyester; adding additives to the reclaimed properties to adjust for example, the color and/or viscosity, and providing the additive-containing reclaimed polyester as output.

Abstract: A method for rotary die cutting. The method may include providing, to an accumulator, an input comprising a melt. The method may include processing, by the accumulator utilizing a set of rolls, the melt to form a sheet of material. The method may include providing, from the accumulator, the sheet of material to a dandy roll. The method may include providing, from the dandy roll, the sheet of material to a rotary die. The method may include cutting, by the rotary die, a product from the sheet of material. The method may include providing, from the rotary die, the product to a stacker.

Abstract: A method for reclaiming polyester can include: providing a feed of recycled polyester 420; providing a feed of polyester precursors 422; depolymerizing the recycled polyester 420 to obtain depolymerized polyester monomers 421; polymerizing the depolymerized polyester monomers 421 with the polyester precursors 422 to form a reclaimed polyester 423; and providing the reclaimed polyester 423 as output 102.

Abstract: A system for making PET objects including a means for reacting a first PET precursor and a second PET precursor to produce a PET melt; a means for flowing the PET melt to a valve having at least two outlets; a means for flowing the PET melt from at least one of the at least two outlets to at least one die forming line and one pelletizing (cutter) line. A means for controlling individually the mass flow of the PET melt in each of the at least two system lines independently of the other and a means for forming the PET objects from the PET melt. The control scheme is a combination of a feed forward system as well as a feedback loop. The entire control scheme is part of the overall system PLC. The fine tuning of the pressure at the outlet of the die forming loop is controllers to less than +/?1 bar to obtain maximum control of formed part.
