ABSTRACT Recent advances in additive‐assisted plastic biodegradation have revealed multiple pathways—oxidative, hydrolytic, enzymatic, and microbial—that accelerate polymer breakdown in environmental conditions. Innovations in pro‐oxidant, hydrolysis‐promoting, microbial nutrient, enzyme‐releasing, and surface‐activating additives have expanded the toolkit for enhancing polymer degradation through complementary chemical and biological mechanisms. Applying these insights to textiles provides a pr
