在使用/寿命结束的硬盘驱动器（EoU/L HDD）中的剩余价值通常无法得到最佳恢复。硬盘的不当收集和回收不仅导致全球环境和社会问题日益严重，而且还导致经济转型和价值的重大损失。目前，废旧硬盘驱动器的最佳处理方案是通过基于粉碎的回收工艺回收效率最高的金属，如钢和铝，这会导致价值和材料泄漏。在EoU/L HDD中检索剩余值的复杂性要求对可用于恢复的HDD的全球供应有更大的了解。本文的目的是首先确定发展中国家和发达国家之间的新的和旧的硬盘驱动器的跨境全球运输的地理模式，然后捕捉和量化的价值泄漏带来几个独特的观点。进行了两项分析。首先，在全球范围内，由于钕（Nd）的回收不足而造成的价值损失被量化。其次，捕获由于HDD的按时重用延迟而导致的价值泄漏。此外，已经确定了正确恢复HDD的核心挑战，消费电子行业可以做出重大贡献。HDD可以为其他电子设备的恢复提供重要的见解，因此HDD的发现可以用于其他类型的电子产品。
The remaining value within end‐of‐use/life hard disk drives (EoU/L HDDs) is often not optimally recovered. The improper collection and recovery of HDDs contribute not only to rising environmental and social concerns worldwide, but also to the transformation of the economy and a significant loss of value. Currently, the most preferred treatment option for used hard drives is to recover the metals with the highest recycling effectiveness, such as steel and aluminum, via a shredding‐based recycling process that results in both value and material leakages. The complexity of retrieving the remaining values within EoU/L HDDs demands a larger view of the global supply of HDDs available for recovery. The aim of this paper is to first identify the geographical patterns of transboundary global shipments of new and used HDDs between developing and developed regions, and then capture and quantify the value leakage by bringing several unique perspectives. Two analyses have been conducted. First, the loss of value due to the insufficient recovery of neodymium (Nd) at the global level is quantified. Second, the value leakage as a result of the delay on on‐time reuse of HDDs is captured. Furthermore, the central challenges toward proper recovery of HDDs, where consumer electronic industry can make significant contributions, have been identified. HDDs are well positioned to contribute important insights to the recovery of other electronic devices, so the findings from HDDs can be adopted for other types of electronics.
