Western Digital recently announced a collaboration with Microsoft, Critical Materials Recycling (CMR), and PedalPoint Recycling to launch a cross-industry pilot program in the U.S. focused on rare earth recycling. The initiative aims to convert roughly 50,000 pounds of discarded mechanical hard drives, mounting brackets, and other materials into high-value raw materials while minimizing environmental impact. Mechanical hard drives rely on rare earth elements such as neodymium (Nd), praseodymium (Pr), and dysprosium (Dy) for accurate data reading and writing, yet traditional recycling methods recover only a small portion of these critical elements.
Using advanced acid-free dissolution technology and a new classification system, Western Digital has successfully and efficiently recovered rare earth elements including neodymium, praseodymium, and cerium, alongside metals like gold, copper, aluminum, and steel. The pilot program has processed over 50,000 pounds of discarded HDDs and peripherals, achieving a rare earth recovery rate of approximately 90% and a total raw material reuse rate of 80%. Compared to traditional mining, this method can reduce greenhouse gas emissions by nearly 95%, marking a key step toward establishing an independent rare earth recycling supply chain in the United States.
