In order to meet the growing energy crisis of the 21st century, the utilization of bio-based materials has become a field of high research endeavour. In view of that, the present review paper is focused on different techniques that are frequently explored for the synthesis of value-added crystalline derivatives of cellulose like MCC and NCC from agricultural wastes and forest residues. Moreover, a comparative analysis between thermochemical and biochemical methods is carried out for such valorization of biomass considering the mechanism involved with various reactions. Further, a critical analysis is performed on various individual techniques specifically used for the applications of MCC and NCC in different fields including environmental, polymer industry, pharmaceutical and other emerging sectors. This article will assist the readers not only to explore new biomass sources but also provides an in-depth insight on various green and cost-effective methods for sustainable production of crystalline cellulose.
为了应对 21 世纪不断增长的能源危机，生物基材料的利用已成为一个备受关注的研究领域。有鉴于此，本综述论文重点介绍了从农业废弃物和森林残留物中合成纤维素增值结晶衍生物 MCC 和 NCC 时常用的不同技术。此外，还针对生物质的这种增值利用，对涉及各种反应的热化学和生物化学方法进行了比较分析。此外，还对 MCC 和 NCC 在环境、聚合物工业、制药和其他新兴领域等不同领域的应用中具体使用的各种技术进行了详细的分析。本文不仅可以帮助读者探索新的生物质资源，还可以深入了解可持续生产结晶纤维素的各种绿色且具有成本效益的方法。
