Abstract: A poly(vinyl acetal) composition, such as a poly(vinyl butyral) composition or resin, can be made containing recycle content by the use of a recycle content aldehyde composition as a feedstock to make the PVA or by application of a recycle allotment, such as an allocation or credit, applied to either the aldehyde composition or to the PVA composition. The recycle content is obtained by cracking a recycle content pyrolysis oil to make a variety of olefins, such as propylene or ethylene.

Abstract: Processes and facilities for producing a recycled content organic chemical compound directly or indirectly from waste plastic. Processing schemes are described herein for converting waste plastic (or hydrocarbon having recycled content derived from waste plastic) into useful intermediate chemicals and final products. In some aspects, recycled content aromatics (r-aromatics) can be processed to provide recycled content paraxylene (r-paraxylene), which can then be used to provide recycled content terephthalic acid (r-TPA) and/or recycled content polyethylene terephthalate (r-PET).

Abstract: A hydrocarbon cracker stream is combined with recycle content pyrolysis oil to form a combined cracker stream and the combined cracker stream is cracked in a cracker furnace to provide an olefin-containing effluent. The r-pyoil can be fed to the cracker feed. Alternatively, the r-pyoil with a predominantly C4-C7 fraction can be fed to the cracker feed. The furnace can be a gas fed furnace, or split cracker furnace.

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: Methods and systems are provided for the conversion of waste plastics into various useful downstream recycle-content products. More particularly, the present system and method involves pyrolyzing one or more waste plastics into various pyrolysis products, including a carbon solids-containing pyrolysis residue, and then subjecting the pyrolysis residue to partial oxidation gasification to thereby form a syngas composition.

Abstract: A pyrolysis method and system are provided that utilizes a multistage dehalogenation method to effectively remove halogen-containing compounds that are present in an initial recycled plastic feedstock. More particularly, the multistage dehalogenation system and process may involve physical sorting the plastic feedstock, melting and separating the feedstock, and subjecting the feedstock a two-stage pyrolysis with intermediate HCl removal.

Abstract: Integrated processes and facilities for providing recycled content hydrocarbon products (r-products) from mixed waste plastic are provided. Carbon dioxide capture and energy recovery from one or more process streams described herein increase energy efficiency and help reduce overall environmental impact while producing valuable final products from chemically recycled waste plastic.

Abstract: A composition having a recycle content value is obtained by reacting a recycle content feedstock to make a recycle content alpha olefin or by deducting from a recycle inventory a recycle content value applied to an alpha olefin composition. At least a portion of the recycle content value in the feedstock or in an allotment obtained by an alpha olefin manufacturer has its origin in recycled waste and/or pyrolysis of recycled waste and/or in thermal steam cracking of recycle content pyoil.
