Lignocellulosic biomass has great potential as an inedible feedstock for bioplastic synthesis, although its use is still limited compared to current edible feedstocks of glucose and starch. This review focuses on recent advances in the production of biopolymers and biomonomers from lignocellulosic feedstocks with downstream processing and chemical polymer syntheses. In microbial production, four routes composed of existing poly (lactic acid) and polyhydroxyalkanoates (PHAs) and the emerging biomonomers of itaconic acid and aromatic compounds were presented to review present challenges and future perspectives, focusing on the use of lignocellulosic feedstocks. Recently, advances in purification technologies decreased the number of processes and their environmental burden. Additionally, the unique structures and high-performance of emerging lignocellulose-based bioplastics have expanded the possibilities for the use of bioplastics. The sequence of processes provides insight into the emerging technologies that are needed for the practical use of bioplastics made from lignocellulosic biomass.
木质纤维素生物质作为生物塑料合成的不可食用原料具有巨大的潜力,尽管与目前的葡萄糖和淀粉等可食用原料相比,其应用仍然有限。本综述重点介绍了木质纤维素原料生产生物聚合物和生物单体的最新进展,以及下游加工和化学聚合物合成。在微生物生产中,提出了由现有聚乳酸和聚羟基烷酸 (PHA) 以及新兴的衣康酸和芳香族化合物生物单体组成的四条路线,以回顾当前的挑战和未来的展望,重点是使用木质纤维素原料。最近,纯化技术的进步减少了工艺数量及其对环境的负担。此外,新兴的基于木质纤维素的生物塑料具有独特的结构和高性能,扩大了生物塑料的使用可能性。该工艺顺序为我们提供了对新兴技术的深入了解,这些技术是木质纤维素生物质生物塑料实际应用所必需的。
