Fiber-reinforced polymer composites, reaching a production of approximately 2.56 million tons in 2023 in Europe, display unique properties, yet they are disposed of at their end of service by conventional methods such as landfill and incineration. Here, we review the recycling of fiber-reinforced polymer wastes in the construction industry, with emphasis on fiber-reinforced polymer composites, recycling methods, and applications of carbon and glass fiber polymer composites in civil engineering. Recycling methods include mechanical, thermal, and chemical techniques. Applications comprise the use in fine fillers, coarse and fine aggregates, macro-fibers, alkali-activated materials, geopolymers, asphalt composites, and cement composites. We discuss workability, mechanical properties including compressive, flexural and tensile properties, durability, and surface modification. Future applications include three-dimensional concrete printing, self-sensing cement composites, self-heating and energy harvesting cement composites, and electromagnetic shielding. We propose a waste management hierarchy, considering the source of composites and their intended applications, to improve circularity.

纤维增强聚合物复合材料在欧洲的产量到 2023 年将达到约 256 万吨，具有独特的性能，但在使用结束后会通过垃圾填埋和焚烧等传统方法进行处理。在此，我们回顾了建筑行业中纤维增强聚合物废料的回收利用，重点介绍了纤维增强聚合物复合材料、回收方法以及碳纤维和玻璃纤维聚合物复合材料在土木工程中的应用。回收方法包括机械、热和化学技术。应用包括细填料、粗骨料和细骨料、粗纤维、碱活化材料、地质聚合物、沥青复合材料和水泥复合材料。我们讨论可加工性、机械性能（包括压缩、弯曲和拉伸性能）、耐久性和表面改性。未来的应用包括三维混凝土打印、自感知水泥复合材料、自加热和能量收集水泥复合材料以及电磁屏蔽。我们提出了废物管理层次结构，考虑到复合材料的来源及其预期应用，以提高循环性。
