第一批商业风力发电场的寿命终止（EOL）阶段正在快速接近，如何处理其不可生物降解的纤维增强聚合物（FRP）复合材料风力涡轮机叶片仍存在不确定性。改变用途的选择可能会延迟大量材料进入不可持续的废物流，如垃圾填埋或焚烧，并有助于循环经济。为了规划废物管理方法并告知政策制定者、决策者和地方政府的集体团队，必须了解和评估潜在FRP复合叶片废料数量的地理差异。由于叶片的数量和型号的多样性，有关EOL叶片的决策非常复杂，因此必须为每个位置量身定制退役计划。本研究引入了一种创新的时空方法来调查问题的严重性，并使用爱尔兰岛案例研究量化与风力涡轮机叶片EOL阶段相关的叶片废料。通过综合地理信息科学框架和在线决策仪表板评估技术和时空变异性。研究结果表明，到2040年，爱尔兰岛约有53，000吨复合材料将达到EOL阶段，其中最高的材料密度位于该岛的西部和西南部。综合GIS方法提供了叶片类型和模型的重要信息，以协助决策的玻璃钢复合材料叶片的再利用策略的设计，并提供了一个范例，为其他国家。
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.
