Sustainable polymers from lignocellulosic biomass have the potential to reduce the environmental impact of commercial plastics while also offering significant performance and cost benefits relative to petrochemical-derived macromolecules. However, most currently available biobased polymers are hampered by insufficient thermomechanical properties, low economic feasibility (e.g., high relative cost), and reduced scalability in comparison to petroleum-based incumbents. Future biobased materials must overcome these limitations to be competitive in the marketplace. Additionally, sustainability challenges at the beginning and end of the polymer lifecycle need to be addressed using green chemistry practices and improved end-of-life waste management strategies. This viewpoint provides an overview of recent developments that can mitigate many concerns with present materials and discusses key aspects of next-generation, biobased polymers derived from lignocellulosic biomass.

高分子科学观点一百周年：来自木质纤维素生物质的聚合物。当前的挑战和未来的机遇

来自木质纤维素生物质的可持续聚合物有可能减少商业塑料对环境的影响，同时相对于石化衍生的大分子而言，还具有显着的性能和成本优势。然而，与基于石油的现有产品相比，大多数目前可用的生物基聚合物受到热机械性能不足、经济可行性低（例如，相对成本高）和可扩展性降低的阻碍。未来的生物基材料必须克服这些限制才能在市场上具有竞争力。此外，需要使用绿色化学实践和改进的报废废物管理策略来解决聚合物生命周期开始和结束时的可持续性挑战。
