1. A process for preparing a recycle cellulose ester (cellulose ester) comprising: (1) obtaining a recycled ethylene composition (r-ethylene) derived directly or indirectly from cracking a recycle content pyrolysis oil composition (r-pyoil), wherein the pyrolysis oil composition is not subjected to hydrogenation; (2) using the r-ethylene as a feedstock in a reaction scheme to produce at least one cellulose reactant for preparing a cellulose ester; and (3) reacting said at least one cellulose reactant to prepare at least one cellulose ester; wherein the r-pyoil is made from a waste plastic-containing stream that comprises at least 30 wt % waste plastic, and wherein the at least 30 wt % waste plastic comprises not more than 5 wt % of polyvinyl chloride.
