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 processed mixed plastic waste streams

A stable catalyst solution suitable for catalyzing the polycondensation of reactants to make polyester polymers comprising:

Non-precipitating alkali/alkaline earth metal and aluminum solutions made with polyhydroxyl ether solvents

In a process for producing a polyester containing 1,4-cyclohexanedimethanol (CHDM) as one of its glycol components, an aqueous or a methanolic slurry comprising CHDM and a dicarboxylic acid is prepared. The slurry is maintained at a temperature below the melting point of CHDM. The slurry is then fed into a reactor. The slurry is esterified at sufficient temperatures and pressures, and optionally in the presence of a suitable catalyst, to effect esterification. A prepolymer is formed. The prepolymer is then polycondensed at sufficient temperatures and pressures in the presence of a suitable catalyst to effect polycondensation to form a polyester.
