Abstract：
By 2050, approximately 43 million tons of wind-turbine blade (WTB) waste materials will have accumulated, emphasizing the critical importance of effective waste management strategies for WTBs at the end of their life cycle to ensure sustainability. Comparing current WTB waste management methods, reuse emerges as a highly-sustainable method that can also serve as a sustainable solution to environmental challenges, including global warming and natural resource depletion associated with civil engineering activities. This paper presents a comprehensive review of sustainable solutions for reusing WTB waste materials in civil engineering applications. Repurposing WTB waste materials as structural elements in housing, urban furniture, recreational facilities, and slow-traffic infrastructure can be a viable option. WTB waste can also be utilized in powder, fiber, and aggregate forms as an eco-friendly material for construction and pavement (e.g., mortar, concrete, asphalt) to replace cement and natural resource aggregates while meeting necessary strength and performance standards. Through a detailed analysis of reusing WTB waste materials, economic and environmental challenges are also discussed. According to the findings, the properties of mortar, concrete, and asphalt can be affected by the type, shape, and content of fibers, polymers, and impurities present in the blades, as well as the cutting direction. Furthermore, while reuse is considered a sustainable end-of-life (EoL) option for WTB waste management from both economic and environmental perspectives, further research is required to fully understand the environmental consequences of this method.
摘要：
到2050年，大约4300万吨风力涡轮机叶片（WTB）废料将积累，强调在WTB生命周期结束时有效的废物管理策略至关重要，以确保可持续性。比较当前的WTB废物管理方法，再利用成为一种高度可持续的方法，也可以作为应对环境挑战的可持续解决方案，包括与土木工程活动相关的全球变暖和自然资源枯竭。本文提出了在土木工程应用中重复使用WTB废料的可持续解决方案的全面回顾。将WTB废料重新用作住房中的结构元件，城市家具,娱乐设施,而慢交通基础设施可能是一个可行的选择。WTB废物也可以用于粉末，纤维,和骨料形式作为建筑和路面的环保材料(例如，砂浆,混凝土,沥青）以替代水泥和自然资源骨料，同时满足必要的强度和性能标准。通过对WTB废料再利用的详细分析,还讨论了经济和环境挑战。根据调查结果,砂浆的性质，混凝土,沥青会受到类型的影响，形状,和纤维含量，聚合物，和叶片中存在的杂质，以及切割方向。此外，尽管从经济和环境的角度来看，再利用被认为是WTB废物管理的可持续报废（EoL）选择，需要进一步的研究才能充分了解这种方法对环境的影响。
