Abstract
An apparatus for depolymerizing recycled polyester into its component ester monomers and half esters includes a first reactor for depolymerizing the recycled polyester, a separator for separating ester monomeric components and half-esters from secondary materials produced in the first reactor, and a second reactor for producing a low molecular weight polyester from liquefied separator products.
