Polyglycolic acid (PGA) is a biodegradable polymer whose market demand is steadily increasing. The methyl glycolate route represents a key technological pathway for its production. This study examines the technical bottlenecks, economic feasibility, and industrialization roadmap for PGA synthesis from methyl glycolate. It identifies monomer purification and polymerization-process control as the core technical bottlenecks, and concludes that process optimization is the critical lever for improving economic viability. An industrial implementation plan encompassing reactor selection and process integration is proposed. The findings provide both technical support and theoretical guidance for commercial deployment of the technology, facilitating large-scale development of the PGA industry.
