Abstract

Over the past two decades, the wind turbine industry has grown rapidly. As a result, thousands of tons of composite materials from these end-of-life (EoL) wind turbine blades (WTBs) are discarded every year. Due to their complex structure, which consists of a thermoset matrix with glass (GF) and/or carbon (CF) fibers, their recovery is a challenge and remains limited. The objective of this study is to compare several recycling techniques for composite materials using landfill as a baseline scenario. Several aspects can influence the performance of GF and CF recovery, but one of the most important is the efficiency of recycling technologies in terms of the recovered GF/CF fiber rate. To evaluate this amount of fiber annually, a material flow analysis (MFA) was performed based on the punctual years of 2030, 2040, and 2050. A correlation with other aspects was established and based on maturity level, technical, economic, and environmental aspects. Afterward, recommendations on short and medium/long term circularity objectives were drafted on the most suitable technologies for WTBs circularity.

通过不同的增值技术从风力涡轮机叶片中回收玻璃纤维和碳纤维的可能性

在过去的二十年里，风力涡轮机行业发展迅速。因此，每年有数千吨来自这些报废(EoL)风力涡轮机叶片(WTBs)的复合材料被丢弃。由于其结构复杂，由玻璃(GF)和/或碳(CF)纤维的热固性基体组成，其恢复是一个挑战，并且仍然有限。本研究的目的是比较几种以垃圾填埋为基准的复合材料回收技术。影响GF/CF回收性能的因素有几个，其中最重要的是回收技术的效率，即GF/CF纤维的回收率。为了评估每年的纤维量，根据2030年、2040年和2050年的准时年份进行了物质流分析(MFA)。在成熟度、技术、经济和环境方面建立了与其他方面的相关性。随后，就wtb循环的最合适技术起草了关于短期和中期/长期循环目标的建议。

期刊介绍： Having been in continuous publication since 1977, Wind Engineering is the oldest and most authoritative English language journal devoted entirely to the technology of wind energy. Under the direction of a distinguished editor and editorial board, Wind Engineering appears bimonthly with fully refereed contributions from active figures in the field, book notices, and summaries of the more interesting papers from other sources. Papers are published in Wind Engineering on: the aerodynamics of rotors and blades; machine subsystems and components; design; test programmes; power generation and transmission; measuring and recording techniques; installations and applications; and economic, environmental and legal aspects.
