Abstract

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

Claims (4)

1. A method of making recycle content mixed ester composition (“r-EC”), said method comprising reacting an alcohol composition at least a portion of which is derived directly or indirectly from pyrolyzing a recycled waste (“pr-ROH”) with an acid to produce a mixed ester effluent comprising r-EC wherein the alcohol composition is a pyrolysis recycle content alcohol composition (“pr-ROH”), wherein at least a portion of said pr-ROH is produced by cracking r-pyoil, wherein said r-pyoil has a C 8 + content of at least 15 weight percent, based on the total weight of said r-pyoil; and wherein said r-pyoil comprises not more than about 20 weight percent total aromatics, based on the total weight of said r-pyoil.

2. A recycle content mixed ester composition (“r-EC”) obtained by claim 1 .

3. The method of claim 1 ; wherein at least a portion of a recycle content allotment being transferred is the recycle content in the pr-ROH supplied.

4. The method of claim 1 , wherein a recycle content value applied to EC drawn from a recycle inventory is derived directly or indirectly from the pyrolysis of recycled waste.
