Abstract
A method for reclaiming 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; and providing the reclaimed polyester as output.
