Agro-waste-based biocomposites are reinforced with natural fibers derived from agricultural residues. These biocomposite materials have attracted a great deal of interest in recent years due to their environmentally friendly and sustainable nature as an alternative to conventional synthetic materials. Issues of environmental sustainability and the search for waste management solutions have driven research into the development of materials that minimize reliance on nonrenewable resources and have a low environmental impact. This review presents an overview of the physical and mechanical properties of some selected biocomposites derived from rice husk, coconut shell, and sugarcane bagasse. Critical properties such as density, water absorption, tensile strength, flexural strength, and impact resistance have been investigated, as these properties largely determine the practicality of the derived materials. In this regard, this paper reiterates the need for further investigation of agro-waste-based biocomposites as an effective alternative toward greener and more eco-friendly industrialization. These materials will offer great opportunities not only to reduce the environmental footprint, but also to increase the value of agricultural waste by promoting a circular economy.
以农业废弃物为基础的生物复合材料由源自农业残余物的天然纤维增强。近年来，这些生物复合材料因其环保和可持续的特性，作为传统合成材料的替代品而备受关注。环境可持续性问题以及对废物管理解决方案的探索推动了对材料开发的研究，这些材料尽量减少对不可再生资源的依赖，并具有较低的环境影响。本综述概述了一些选自稻壳、椰壳和甘蔗渣的生物复合材料的物理和机械性能。研究了密度、吸水性、拉伸强度、弯曲强度和抗冲击性等关键性能，因为这些性能在很大程度上决定了衍生材料的实用性。在这方面，本文重申需要进一步研究以农业废弃物为基础的生物复合材料，作为实现更绿色、更环保工业化的有效替代品。这些材料不仅将提供减少环境足迹的巨大机会，还将通过促进循环经济来提高农业废弃物的价值。
