Abstract The conversion of discarded polyethylene terephthalate (PET) into bioplastics polyglycolic acid (PGA) represents a pivotal step in promoting the reuse PET and bolstering adoption PGA. However, this promising pathway is currently hindered by (i) low rate PET-derived ethylene glycol (EG) glycolate (ii) high cost associated with purifying glycolic (GA). Herein, we designed novel Pd-CoCr2O4/NF catalyst for continuous electrosynthesis glycolate, achieving 75% EG at current density ~280 mA cm–2. Furthermore, devised cost-effective purification process that circumvents unnecessary acidification steps. A scale-up experiment involving 20 kg waste was conducted resulted an 87% PGA yield. Techno-economic analysis confirmed competitiveness produced through environmental-friendly method. This study shows sustainable route to mitigate environmental impact plastics reduce production costs bioplastics.
