  • Recycled Polyglycolic Acid: Advanced Strategies For Sustainable Production, Chemical Recycling, And High-Performance Applications

    Recycled polyglycolic acid (PGA) represents a critical frontier in sustainable polymer science, combining the inherent biodegradability and biocompatibility of virgin PGA with circular economy principles. As the simplest linear aliphatic polyester, PGA exhibits exceptional gas barrier properties, mechanical strength, and complete biodegradation into non-toxic metabolites [5]. However, industrial-scale recycling of polyglycolic acid presents unique technical challenges stemming from its high melting point (215–225°C), thermal sensitivity during melt processing, and the need to preserve molecular weight and crystallinity through recycling cycles [2]. This article provides a comprehensive analysis of chemical recycling pathways, depolymerization-repolymerization strategies, quality control parameters, and emerging applications for recycled polyglycolic acid targeting R&D professionals developing next-generation sustainable materials.
