来自木质纤维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，同时与石化衍生的大分子相比，还提供了显着的性能和成本效益。然而，与基于石油的现有聚合物相比，目前可用的大多数生物基聚合物存在热机械性能不足、经济可行性较低(例如，相对成本较高)以及可扩展性降低的问题。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，聚合物生命周期开始和结束时的可持续性挑战需要使用绿色化学做法和改进的寿命结束废物管理战略来解决。这一观点概述了可以缓解对现有材料的许多担忧的最新发展，并讨论了从木质纤维生物质衍生的下一代生物基聚合物的关键方面。
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 macro-molecules. 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.
