32: From Mechanical to Molecular: What ‘Advanced Recycling’ Actually Means

The Center for Energy Studies recently hosted its second annual sustainability summit, bringing together experts to examine sustainability challenges from a systems-level perspective. In this episode of “The Energy Forum,”  Rachel A. Meidl is joined by two speakers from the summit: Marco Castaldi, professor at City College of New York and cochair of the Recycling Science Council, and Katherine Hofman, sustainability strategic initiatives manager at Eastman. Together, they unpack the growing confusion around plastics recycling, particularly the terminology and taxonomy surrounding advanced recycling. They discuss how mechanical recycling differs from advanced, molecule‑level processes; why oversimplified narratives about recycling can mislead policymakers and the public; and how clearer definitions can shape more informed  regulations, investments, and waste‑reduction strategies.
