Lignin based biopolymer (value added products) production is the most promising technology in the perspective of lignin valorization and sustainable development. Valorization of lignin gain the potentials to produce biopolymers such as polyhydroxyalkanoates, polyhydroxybutyrates, polyurethane etc. However, lignin valorization processes still needs development due to the recalcitrant nature of lignin which restricts its potential to produce valuable products. Many novel extraction strategies have been developed to fragment the lignin structure and make ease the recovery of valuable products. Achieving in depth insights on lignin characteristics and structure will help to understand the metabolic and catalytic degradative pathways needed for lignin valorization. In the view of multipurpose characteristics of lignin for biopolymer production, this review will spot light the potential applications of lignin and lignin based derivatives on biopolymer production, various lignin separation technologies, lignin depolymerization process, biopolymers production strategies and the challenges in lignin valorization will be addressed and discussed.

从木质素增值和可持续发展的角度来看，木质素基生物聚合物（增值产品）生产是最有前途的技术。木质素的均价化获得了生产生物聚合物的潜力，例如聚羟基链烷酸酯，聚羟基丁酸酯，聚氨酯等。然而，由于木质素的顽强特性限制了其生产有价值的产品的潜力，木质素的均价化工艺仍需要发展。已经开发出许多新颖的提取策略来破碎木质素结构并简化有价值产品的回收。深入了解木质素的特性和结构将有助于了解木质素增值所需的代谢和催化降解途径。考虑到木质素在生物聚合物生产中的多用途特性，
