Abstract: The present invention relates to the combination of certain flame retardant additives in a copolyester to improve the flame retardant properties of the copolyester composition while retaining clarity and impact properties, methods of making the copolyester composition and articles made from the copolyester composition. More specifically, the present invention relates to the use of brominated flame retardant compounds in copolyester compositions to improve the flame retardant properties while surprisingly retaining clarity, glass transition temperature, and impact properties.
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 and facilities for producing recycled chemical products from waste plastic are described herein. The processes include treating process streams, such as a pyrolysis gas stream and/or at least a portion of a cracker furnace effluent stream, in a caustic scrubber process to remove certain components, such as carbon dioxide. The spent caustic solution from the caustic scrubber process is then recycled and reused in other caustic processes within the facility, which can include a halogen neutralization process from removing halogens from a liquification process off-gas.

Abstract: Methods and systems for separating mixed plastic waste are provided herein. The methods generally comprise separating the mixed plastic waste into a PET-enriched stream and one or more PET-depleted streams. The separating may be accomplished using the combinations of two or more density separation stages. Exemplary density separation stages include sink-float separators and centrifugal force separators. The PET-enriched and PET-depleted streams may be recovered and/or directed to downstream chemical recycling processes.
