The End-of-Life (EOL) stage of the first commercial wind farms is fast approaching and uncertainty remains in how to deal with their non-biodegradable Fibre Reinforced Polymer (FRP) composite wind turbine blades. Repurposing options could potentially delay large volumes of material entering unsustainable waste streams such as landfill or incineration and contribute to the circular economy. To plan waste management methods as well as inform the collective team of policy makers, decision makers and local governments, it is essential to understand and assess the geographical variability in the quantity of potential FRP composite blade waste material. Decisions regarding EOL blades are complex due to the varying numbers of blades and diversity in models, therefore it is essential that decommissioning plans are tailored for each location. This research introduces an innovative spatiotemporal approach to investigate the magnitude of the problem and quantify blade waste material associated with the EOL stage of wind turbine blades using the island of Ireland case study. The technical and spatiotemporal variability is assessed through an integrated Geographical Information Science (GIS) framework and online dashboard for decision-making. The findings indicate that for the island of Ireland approximately 53,000 tonnes of composite material will reach the EOL stage by 2040 with highest material densities located in the west and southwest of the island. The integrated GIS approach provides important information on blade type and model to assist decision-making on the design of repurposing strategies for FRP composite blades and provides an exemplar for other countries.

第一个商业风电场的寿命终止（EOL）阶段即将来临，如何处理其不可生物降解的纤维增强聚合物（FRP）复合风力涡轮机叶片仍存在不确定性。重新选择方案可能潜在地延迟大量材料进入不可持续的废物流，例如垃圾填埋场或焚化炉，并有助于循环经济。为了规划废物管理方法并告知决策者，决策者和地方政府的集体团队，必须了解和评估潜在的FRP复合材料叶片废料数量的地域变异性。由于叶片数量的变化和模型的多样性，有关EOL叶片的决策很复杂，因此必须针对每个位置量身定制退役计划。这项研究引入了一种创新的时空方法，以爱尔兰岛为例，研究问题的严重程度并量化与风力涡轮机叶片的停产阶段有关的叶片废料。技术和时空变异性通过集成的地理信息科学（GIS）框架和在线仪表板进行决策评估。研究结果表明，到爱尔兰岛，到2040年，大约53,000吨的复合材料将达到EOL阶段，其中材料密度最高的将位于该岛的西部和西南部。集成的GIS方法可提供有关叶片类型和模型的重要信息，以协助决策制定FRP复合叶片的再利用策略，并为其他国家提供范例。
