Rare earths conflict with China giving new life to old PCs, phones

As the U.S. and China vie for economic, technological and geopolitical supremacy, the critical elements and metals embedded in technology from consumer to industrial and military markets have become a pawn in the wider conflict. That’s nowhere more so the case than in China’s leverage over the rare earth metals supply chain. This past week, the Department of Defense took a large equity stake in MP Materials, the company running the only rare earths mining operation in the U.S.

But there’s another option to combat the rare earths shortage that goes back to an older idea: recycling. The business has come a long way from collecting cans, bottles, plastic, newspaper and other consumer disposables, otherwise destined for landfills, to recreate all sorts of new products.

Today, next-generation recyclers — a mix of legacy companies and startups — are innovating ways to gather and process the ever-growing mountains of electronic waste, or e-waste, which comprises end-of-life and discarded computers, smartphones, servers, TVs, appliances, medical devices, and other electronics and IT equipment. And they are doing so in a way that is aligned to the newest critical technologies in society. Most recently, spent EV batteries, wind turbines and solar panels are fostering a burgeoning recycling niche.

The e-waste recycling opportunity isn’t limited to rare earth elements. Any electronics that can’t be wholly refurbished and resold, or cannibalized for replacement parts needed to keep existing electronics up and running, can berecycled to strip out gold, silver, copper, nickel, steel, aluminum, lithium, cobalt and other metals vital to manufacturers in various industries. But increasingly, recyclers are extracting rare-earth elements, such as neodymium, praseodymium, terbium and dysprosium, which are critical in making everything from fighter jets to power tools.

“Recycling [of e-waste] hasn’t been taken too seriously until recently” as a meaningful source of supply, said Kunal Sinha, global head of recycling at Swiss-based Glencore, a major miner, producer and marketer of metals and minerals — and, to a much lesser but growing degree, an e-waste recycler. “A lot of people are still sleeping at the wheel and don’t realize how big this can be,” Sinha said. 

Traditionally, U.S. manufacturers purchase essential metals and rare earths from domestic and foreign producers — an inordinate number based in China — that fabricate mined raw materials, or through commodities traders. But with those supply chains now disrupted by unpredictable tariffs, trade policies and geopolitics, the market for recycled e-waste is gaining importance as a way to feed the insatiable electrification of everything.

“The United States imports a lot of electronics, and all of that is coming with gold and aluminum and steel,” said John Mitchell,…
