风力发电行业发展迅速。风力涡轮机（WT）被认为是一种低环境影响的能源发电技术。虽然WT的使用寿命相对较长（20-40年），但在某些时候，大量WT将达到其使用寿命的终点。为了从这些风力发电机中回收最大价值，对风力发电机的使用寿命（EOSLWT）进行规划至关重要。从历史上看，WT的环境生命周期评估通常只考虑材料提取和加工，制造和使用阶段，将EOSLWT的管理排除在其关注范围之外。提出了对风能技术的持续发展至关重要的四个关键EOSLWT问题：i）鉴于行业的快速增长率和大量现有安装的WT，EOSLWT管理的挑战; ii）EOSLWT替代方案，如再制造和回收，以分别恢复功能和材料价值; iii）WT逆向供应链中的关键活动，如回收方法、运输物流、退货质量和再加工WT的质量;以及iv）与EOSLWT相关的经济和商业问题。预计所提供的讨论将激发决策者之间的对话，并提高对风电行业经济机遇和意外挑战的认识。
The wind power industry is growing rapidly. Wind turbines (WTs) are perceived as a low environmental impact energy generation technology. While the service life of a WT is relatively long (20–40 years), at some point a significant number of WTs will reach the end of their service lives. To recover maximum value from these WTs, planning for the end-of-service life of wind turbines (EOSLWTs) is paramount. Historically, environmental life cycle assessments of WTs have often only considered the materials extraction and processing, manufacturing, and use phases, leaving the management of EOSLWTs outside the scope of their attention. Four key EOSLWTs issues that are essential for the continuing development of wind energy technologies are presented: i) The challenges of managing of EOSLWTs given the fast growth rate of the industry and the large number of existing installed WTs; ii) The EOSLWT alternatives such as remanufacturing and recycling to recover functional and material value respectively; iii) The critical activities in the WT reverse supply chain such as recovery methods, logistics of transportation, quality of returns, and quality of reprocessed WTs; and iv) The economic and business issues associated with EOSLWTs. It is expected that the discussion provided will stimulate a dialog among decision makers and raise awareness of economic opportunities and unanticipated challenges in the wind power industry.
