The main product losses occur at the stage of monomer production and purification. Losses are about 50-60%. The purpose of this work is to choose the optimal path and purification of glycolide. In this paper, we conducted and presented a comprehensive literature review on methods for producing glycolic acid, glycolide, and purification and polymerization of glycolide. Different catalysts were compared at the stages of glycolide polycondensation, depolymerization, and polymerization. The work describes the characteristics of the raw materials, describes the methods of production, purification, and polymerization of glycolide
