The Amazon Region (AR), with its vast biodiversity and rich natural resources, presents a unique opportunity for the development of sustainable polymer composites (PCs) reinforced with residues from both timber and agro-extractivism industries. This study explores the potential of Amazonian residues, such as sawdust, wood shavings, and agro-industrial by-products such as açaí seeds and Brazil nut shells, to enhance the mechanical, thermal, and environmental properties of polymer composites. By integrating these natural materials into polymer matrices, significant improvements in the composite performance were achieved, including increased tensile strength, thermal stability, and biodegradability. The study also highlights the environmental and economic benefits of using these residues, promoting waste reduction and supporting a circular economy in the region. Through case studies and detailed analyses, this study demonstrates the feasibility and advantages of incorporating Amazonian residues into composites for a wide range of applications, from construction materials to consumer goods. This approach not only adds value to the by-products of Amazonian industries, but also contributes to the global effort toward sustainable material development.
亚马逊地区（AR）拥有丰富的生物多样性和自然资源，为利用木材和农业提取物工业的残余物增强的可持续聚合物复合材料（PCs）的开发提供了独特机遇。本研究探讨了亚马逊地区的残余物（如锯末、木屑）以及农业工业副产品（如阿萨伊籽和巴西坚果壳）提升聚合物复合材料机械、热和环境性能的潜力。通过将这些天然材料融入聚合物基体，复合材料性能得到显著改善，包括拉伸强度提高、热稳定性增强和生物降解性提升。该研究还强调了使用这些残余物的环境和经济效益，促进了该地区的废物减少并支持循环经济。通过案例研究和详细分析，本研究证明了将亚马逊地区的残余物纳入复合材料用于从建筑材料到消费品等广泛应用的可行性和优势。这种方法不仅为亚马逊地区工业的副产品增加了价值，也为全球可持续材料开发做出了贡献。
