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.

Abstract: Chemical recycling facilities for processing mixed waste plastic 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 recovery 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: Amorphous polyolefins, such as propylene-ethylene copolymers, having a recycle content value are obtained by reacting a recycle content feedstock to make recycle content amorphous polyolefins or by deducting from a recycle inventory a recycle content value, which is applied to the amorphous polyolefins. At least a portion of the recycle content value in the feedstock or in an allotment obtained by an amorphous polyolefins manufacturer has its origin in recycled waste plastics.

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 heat integration process and system for a chemical recycling facility is provided that can lower the carbon footprint and global warming potential of the facility. More particularly, one or more heat transfer media may be used to recover heat energy from a waste plastic pyrolysis effluent and redistribute the recovered heat energy throughout the chemical recycling facility. Furthermore, at least a portion of the pyrolysis oil produced by the pyrolysis process may be used to liquefy at least a portion of the waste plastics. Thus, the global warming potential of the chemical recycling facility may be optimized and lowered due to the heat integration process and system herein.
