Abstract

Lignocellulosic materials, despite their abundance and attractiveness, have long been marred with challenges in optimising the cost-functionality-quality trade-off. This comprehensive authoritative review paper explores how various lignocellulosic feedstock have been utilised to prepare marketable and sustainable bioplastics, as potential substitutes to conventional petroleum-based packaging. Dependence on hydrocarbon-derived plastics is increasingly being supplanted by both consumer-driven and sustainability-oriented materials design. This comprehensive paper encompasses a broad review relating to recent research (2013−2023) on the innovations and heuristic approaches to modify lignocellulose for the production of packaging films. The review paper holds extensive focus across various lignocellulosic materials such as - but not limited to - cellulose nanomaterials, cellulose esters and grafted cellulose. Advances in processes reported to date such as mechanochemical, chemical, thermochemical, biochemical and other novel methods have been studied. The materials design and process implications in terms of its cost, energy input and sustainability in its true sense, for all known techniques have been extensively investigated in this review paper. The review paper has further provided an elaborate process-structure-property-performance framework that characterises how material properties could be fine-tuned via different process considerations. A techno-economic feasibility overview for said processes and materials' use is also described herein.

可持续包装中的木质纤维素生物塑料--材料设计和加工的最新发展:全面回顾
尽管木质纤维素材料丰富且极具吸引力,但长期以来在优化成本-功能-质量权衡方面一直面临挑战。这篇综合性权威评论文章探讨了如何利用各种木质纤维素原料制备适销对路的可持续生物塑料,作为传统石油基包装的潜在替代品。以消费者需求和可持续发展为导向的材料设计正在逐渐取代对碳氢化合物衍生塑料的依赖。本综合论文广泛综述了近期(2013-2023 年)有关木质纤维素改性用于生产包装薄膜的创新和启发式方法的研究。综述文件广泛关注各种木质纤维素材料,如(但不限于)纤维素纳米材料、纤维素酯和接枝纤维素。对迄今报道的工艺进展,如机械化学、化学、热化学、生物化学和其他新方法进行了研究。本综述论文广泛研究了所有已知技术的材料设计和工艺在成本、能源投入和真正意义上的可持续性方面的影响。综述文件进一步提供了一个详细的工艺-结构-性能框架,说明了如何通过不同的工艺考虑对材料性能进行微调。本文还对上述工艺和材料使用的技术经济可行性进行了概述。
