From PEF to rPEF: disclosing the potential of deep eutectic solvents in continuous de-/re-polymerization recycling of biobased polyesters

Chemical attempts to recycle bio-based poly(ethylene 2,5-furandicarboxylate) (PEF) have not been reported, yet its expected global production, potential accumulation or persistence in the environment calls for innovative solutions. Here, we report the design of a urea : zinc acetate deep eutectic solvent (DES) system for a continuous, eco-friendly and closed-loop approach for recycling PEF into rPEF.
