Here, we synthesize recent advances in lipase-mediated degradation of ester-bond-containing plastics and propose a unifying framework for programmable biodegradation, in which enzyme activity, substrate accessibility, and downstream metabolism are systematically coordinated. Lipases (EC 3.1.1.3) can hydrolyze synthetic polyesters, including polyethylene terephthalate (PET), polyurethane (PU), polylactide (PLA), and polycaprolactone (PCL), but their performance is constrained by polymer crystallinity, limited environmental stability, and restricted substrate specificity. Integrating insights from multi-omics discovery, artificial intelligence-guided enzyme engineering, and systems-level design reveals emerging strategies to enhance catalytic efficiency and environmental robustness. Although engineered enzyme systems can achieve high depolymerization and monomer recovery under controlled conditions, translation to real environments remains limited by diffusion constraints, enzyme inactivation, and regulatory considerations.
