Western Digital, Microsoft Target Rare Earth Metals Through Hard Drive Recycling

Western Digital says it’s created an initiative to retrieve rare earth metals from hard drives that are being cycled out of data centers.

The tech company, best known for its digital storage products, says its Advanced Recycling and Rare Earth Material Capture Program has partnered with Microsoft and two other companies to reclaim rare earth metals including neodymium, dysprosium and praseodymium.

Rare earth elements have taken on new significance amid the trade battles between the US and China. In response to President Donald Trump’s imposition of soaring tariffs on products imported from China, Beijing said last week that it has suspended exports of rare earth minerals to the US. Those minerals are critical to the manufacturing of many high-tech products and are found in products like computers, cars and military hardware.

The hard drives in data center servers are often destroyed for security reasons when systems are upgraded, Jackie Jung, Western Digital’s vice president of global strategy, said in a blog post on Thursday. Recovery of rare earth metals hasn’t always been a priority in that process, according to Jung.

“Rare earths are often melted down with steel because many recovery processes involve a highly corrosive process that is not eco-friendly nor economical – and the rare earths are lost. Our department sought a different approach in the quest to increase the recyclability of HDDs and their valuable materials,” Jung said.

In addition to Microsoft, the program also includes Critical Materials Recycling and Microsoft’s recycling partner company Pedal Point Recycling. The latter two were brought in when the initial pilot program achieved reclaim percentages of over 90%, Jung said.
