1. A process for producing chemicals or polymers from plastic waste, the process comprising:
(a) providing a pyrolysis oil from plastic waste, wherein the pyrolysis oil comprises C2-C5 hydrocarbons and C6+ hydrocarbons;
(b) separating at least a portion of the pyrolysis oil into a pyrolysis gas stream comprising the C2-C5 hydrocarbons and a pyrolysis liquid stream comprising the C6+ hydrocarbons;
(c) providing a co-feed comprising independently a petroleum-based feed, a fossil fuel-based feed, or a bio-based feed;
(d) feeding an NGL unit feed comprising at least a portion of the pyrolysis gas stream and the co-feed to a Natural Gas Liquids (NGL) unit to provide an NGL unit output stream comprising at least one circular product, wherein a fraction of the circular product in the NGL unit output stream which is attributable to the pyrolysis oil or plastic waste is determined by mass balance;
(e) feeding a reforming unit feed comprising at least a portion of the pyrolysis liquid stream and the co-feed to a reforming unit to provide a reforming unit output stream comprising at least one circular product, wherein a fraction of the circular product in the reforming output stream which is attributable to the pyrolysis oil or plastic waste is determined by mass balance; and
(f) processing at least a portion of the NGL unit output stream in a steam cracker as a steam cracker feed to provide a steam cracker output stream comprising at least one circular product, wherein a fraction of the circular product in the steam cracker output stream which is attributable to the pyrolysis oil or plastic waste is determined by mass balance.
