Abstract:

The escalating production and application of polylactic acid (PLA) have intensified the need for efficient recycling methods for its post⁃consumer waste. This review comprehensively summarized recent advancements in PLA synthesis, depolymerization, and chemical recycling. Various depolymerization techniques were critically analyzed with a focus on their reaction mechanisms, catalytic systems, and the resulting product streams. Furthermore, the advantages and limitations of each chemical recycling pathway were evaluated, and future research directions and challenges in establishing a circular economy for PLA were discussed.

Key words: polylactic acid, synthesis, depolymerization, recycle
