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 C₈+ 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.
