Chemical recycling facilities for processing mixed plastic waste are provided herein. Such facilities have the capability of processing mixed plastic waste streams and utilize a variety of recycling facilities, such as, for example, solvolysis facility, a pyrolysis facility, a cracker facility, a partial oxidation gasification facility, an energy generation/energy production facility, and a solidification facility. Streams from one or more of these individual facilities may be used as feed to one or more of the other facilities, thereby maximizing recovery of valuable chemical components and minimizing unusable waste streams.

Chemical recycling of solvolysis coproduct streams

Disclosed is a method for treating the product stream from a polyester methanolysis depolymerization process wherein the product stream includes dimethyl terephthalate and one or more side species selected from the group consisting of dimethyl phthalate, dimethyl isophthalate, bisphenol-A, an adipic acid diester and colorants. The method includes a) hydrogenating said dimethyl terephthalate to form one or more of dimethyl 1,4-cyclohexanedicarboxylate and 1,4-cyclohexanedimethanol; and (b) hydrogenating one or more of said one or more side species of said product stream. A method for depolymerization of polyester is also described.
