Abstract: 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.

Abstract: Processes for producing terephthalic acid are disclosed, the processes including a step of combining in a reaction medium para-xylene, a solvent comprising water and a saturated organic acid having from 2-4 carbon atoms, and an oxygen-containing gas, at a temperature for example from about 145° C. to about 175° C., in the presence of a catalyst composition comprising cobalt, manganese, zirconium, and bromine, wherein the zirconium is present in the reaction medium in an amount, for example, from 1 ppm to 50 ppm with respect to the weight of the liquid in the reaction medium.

Abstract: A process and system for liquefying and dehalogenating a waste plastic are provided. Generally, the process comprises: (a) liquefying solid waste plastic to produce a liquefied waste plastic; (b) heating at least a portion of the molten waste plastic in a heat exchanger to thereby provide a heated liquefied waste plastic; (c) sparging a stripping gas into the heated liquefied waste plastic to produce a multi-phase mixture; and (d) disengaging a gaseous phase from a liquid phase of the multi-phase mixture to thereby provide a halogen-enriched gaseous material and a halogen-depleted liquefied waste plastic.
