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.

Electrochemical upcycling of waste polyethylene terephthalate (PET) into biodegradable polyglycolic acid (PGA) is a promising solution to relieve plastic pollution. However, both the low current density and tedious separation process for target glycolic (GA) products in flow electrolysis have hindered industrial-scale applications. Here, we show an interfacial acid-base microenvironment regulation strategy efficient oxidation PET-derived ethylene glycol (EG) GA using Pd-CoCr2O4 catalysts. Specifically, only cell voltage 1.25 V needed deliver ca. 290 mA cm-2. Moreover, green method developed obtain high-purity (99%). 20 kg PET employed pilot plant test (stack electrolyzer: 324 cm2 × 5), which exhibits 93.0% selectivity at 280 cm-2 (current: 90.72 A) with yield rate 0.32 h-1. After polymerization, PGA can reach up 87%, demonstrating potential this technique large-scale production from PET.
