Abstract

A polyethylene composition having a recycle content value is obtained by reacting a recycle content feedstock to make a recycle content polyethylene or by deducting from a recycle inventory a recycle content value applied to a polyethylene composition. At least a portion of the recycle content value in the feedstock or in an allotment obtained by a polyethylene manufacturer has its origin in recycled waste plastics.

Claims (24)

1 - 32 . (canceled)

33 . A method of processing a pyrolysis recycle content ethylene composition derived directly or indirectly from pyrolysis of a waste plastic (“pr-ethylene”), a POX gasification recycle content ethylene composition derived directly or indirectly from POX gasification of said waste plastic (“POXr-ethylene”), and/or a solvolysis recycle content ethylene composition derived directly or indirectly from solvolysis of said waste plastic (“sr-ethylene”), said method comprising feeding said pr-ethylene, said POXr-ethylene, and/or said sr-ethylene to a reactor in which a polyethylene is made.

34 . A method of making a recycle content polyethylene composition (“r-polyethylene”), said method comprising polymerizing a recycle content ethylene composition, at least a portion of which is derived directly or indirectly from pyrolyzing, gasifying, and/or solvolyzing a waste plastic, to produce a polyethylene effluent comprising said r-polyethylene.

35 . A method of making a polyethylene comprising a polyethylene manufacturer, or one among its Family of Entities:

a. obtaining an ethylene composition from a supplier and either:

i. from said supplier, also obtaining a pyrolysis recycle content allotment, a POX gasification recycle content allotment, and/or a solvolysis recycle content allotment, or

ii. from any person or entity, obtaining a pyrolysis recycle content allotment, a POX gasification recycle content allotment, and/or a solvolysis recycle content allotment without a supply of said ethylene composition from said person or entity transferring said pyrolysis recycle content allotment, said POX gasification recycle content allotment, and/or said solvolysis recycle content allotment; and

b. depositing at least a portion of said pyrolysis recycle content allotment, said POX gasification recycle content allotment, and/or said solvolysis recycle content allotment obtained in step a(i) or step a(ii) into a recycle inventory; and

c. making a polyethylene composition from any ethylene composition obtained from any source.

36 . The method of claim 33 , wherein said r-olefin, said r-ethylene, or said r-polyethylene is derived directly or indirectly from cracking r-pyoil in a gas furnace.

37 . The method of claim 34 , wherein said r-olefin, said r-ethylene, or said r-polyethylene is derived directly or indirectly from cracking r-pyoil in a gas furnace.

38 . The method of claim 35 , wherein said r-olefin, said r-ethylene, or said r-polyethylene is derived directly or indirectly from cracking r-pyoil in a gas furnace.

39 . The method of claim 33 , wherein at least a portion of said ethylene composition is derived directly or indirectly from said pyrolysis of waste plastic and through said cracking of r-pyoil to thereby obtain an r-ethylene composition.

40 . The method of claim 34 , wherein at least a portion of said ethylene composition is derived directly or indirectly from said pyrolysis of waste plastic and through said cracking of r-pyoil to thereby obtain an r-ethylene composition.

41 . The method of claim 35 , wherein at least a portion of said ethylene composition is derived directly or indirectly from said pyrolysis of waste plastic and through said cracking of r-pyoil to thereby obtain an r-ethylene composition.

42 . The method of claim 33 , wherein r-ethylene is used to make said polyethylene composition.

43 . The method of claim 34 , wherein r-ethylene is used to make said polyethylene composition.

44 . The method of claim 35 , wherein r-ethylene is used to make said polyethylene composition.

45 . The method of claim 42 , wherein said polyethylene is made in an additive polymerization reaction.

46 . The method of claim 43 , wherein said polyethylene is made in an additive polymerization reaction.

47 . The method of claim 44 , wherein said polyethylene is made in an additive polymerization reaction.

48 . The method according to claim 45 , wherein said polyethylene is made in absence of a catalyst.

49 . The method according to claim 46 , wherein said polyethylene is made in absence of a catalyst.

50 . The method according to claim 47 , wherein said polyethylene is made in absence of a catalyst.
