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, president and CEO of the Global Electronics Association, an industry trade group. “So there’s a great opportunity to actually have the tariffs be an impetus for greater recycling in this country for goods that we don’t have, but are buying from other countries.”

With copper, other metals, ‘recycling is going to play huge role’

Although recycling contributes only around $200 million to Glencore’s total EBITDA of nearly $14 billion, the strategic attention and time the business gets from leadership “is much more than that percentage,” Sinha said. “We believe that a lot of mining is necessary to get to all the copper, gold and other metals that are needed, but we also recognize that recycling is going to play a huge role,” he said.

Glencore has operated a huge copper smelter in Quebec, Canada, for almost  20 years on a site that’s nearly 100-years-old. The facility processes mostly mined copper concentrates, though 15% of its feedstock is recyclable materials, such as e-waste that Glencore’s global network of 100-plus suppliers collect and sort. The smelter pioneered the process for recovering copper and precious metals from e-waste in the mid 1980s, making it one of the first and largest of its type in the world. The smelted copper is refined into fresh slabs that are sold to manufacturers and traders. The same facility also produces refined gold, silver, platinum and palladium recovered from recycling feeds. 

The importance of copper to OEMs’ supply chains was magnified in early July, when prices hit an all-time high after President Trump said he would impose a 50% tariff on imports of the metal. The U.S. imports just under half of its copper, and the tariff hike — like other new Trump trade policies — is intended to boost domestic production.

It takes around three decades for a new mine in the U.S. to move from discovery to production, which makes recycled copper look all the more attractive, especially as demand keeps rising. According to estimates by energy-data firm Wood Mackenzie, 45% of demand will be met with recycled copper by 2050, up from about a third today.

Foreign recycling companies have begun investing in the U.S.-based facilities. In 2022, Germany’s Wieland broke ground on a $100-million copper and copper alloy recycling plant in Shelbyville, Kentucky. Last year, another German firm, Aurubis, started construction on an $800-million multi-metal recycling facility in Augusta, Georgia.

“As the first major secondary smelter of its kind in the U.S., Aurubis Richmond will allow us to keep strategically important metals in the economy, making U.S. supply chains more independent,” said Aurubis CEO Toralf Haag.

Massive amounts of e-waste

The proliferation of e-waste can be traced back to the 1990s, when the internet gave birth to the digital economy, spawning exponential growth in electronically enabled products. The trend has been supercharged by the emergence of renewable energy, e-mobility, artificial intelligence and the build-out of data centers. That translates to a constant turnover of devices and equipment, and massive amounts of e-waste.

In 2022, a record 62 million metric tons of e-waste were produced globally, up 82% from 2010, according to the most recent estimates from the United Nations’ International Telecommunications Union and research arm UNITAR. That number is projected to reach 82 million metric tons by 2030.

The U.S., the report said, produced just shy of 8 million tons of e-waste in 2022. Yet only about 15-20% of it is properly recycled, a figure that illustrates the untapped market for e-waste retrievables. The e-waste recycling industry generated $28.1 billion in revenue in 2024, according to IBISWorld, with a projected compound annual growth rate of 8%.

Whether it’s refurbished and resold or recycled for metals and rare-earths, e-waste that stores data — especially smartphones, computers, servers and some medical devices — must be wiped of sensitive information to comply with cybersecurity and environmental regulations. The service, referred to as IT asset disposition (ITAD), is offered by conventional waste and recycling companies, including Waste Management, Republic Services and Clean Harbors, as well as specialists such as Sims Lifecycle Services, Electronic Recyclers International, All Green Electronics Recycling and Full Circle Electronics.

“We’re definitely seeing a bit of an influx of [e-waste] coming into our warehouses,” said Full Circle Electronics CEO Dave Daily, adding, “I think that is due to some early refresh cycles.”

That’s a reference to businesses and consumers choosing to get ahead of the customary three-year time frame for purchasing new electronics, and discarding old stuff, in anticipation of tariff-related price increases.

Daily also is witnessing increased demand among downstream recyclers for e-waste Full Circle Electronics can’t refurbish and sell at wholesale. The company dismantles and separates it into 40 or 50 different types of material, from keyboards and mice to circuit boards, wires and cables. Recyclers harvest those items for metals and rare earths, which continue to go up in price on commodities markets, before reentering the supply chain as core raw materials.

Even before the Trump administration’s efforts to revitalize American manufacturing by reworking trade deals, and recent changes in tax credits key to the industry in Trump’s tax and spending bill, entrepreneurs have been launching e-waste recycling startups and developing technologies to process them for domestic OEMs.

“Many regions of the world have been kind of lazy about processing e-waste, so a lot of it goes offshore,” Sinha said. In response to that imbalance, “There seems to be a trend of nationalizing e-waste, because people suddenly realize that we have the same metals [they’ve] been looking for” from overseas sources, he said. “People have been rethinking the global supply chain, that they’re too long and need to be more localized.” 

China commands 90% of rare earth market

Several startups tend to focus on a particular type of e-waste. Lately, rare earths have garnered tremendous attention, not just because they’re in high demand by U.S. electronics manufacturers but also to lessen dependence on China, which dominates mining, processing and refining of the materials. In the production of rare-earth magnets — used in EVs, drones, consumer electronics, medical devices, wind turbines, military weapons and other products — China commands roughly 90% of the global supply chain.

The lingering U.S.–China trade war has only exacerbated the disparity. In April, China restricted exports of seven rare earths and related magnets in retaliation for U.S. tariffs, a move that forced Ford to shut down factories because of magnet shortages. China, in mid-June, issued temporary six-month licenses to certain major U.S. automaker suppliers and select firms. Exports are flowing again, but with delays and still well below peak levels.

The U.S. is attempting to catch up. Before this past week’s Trump administration deal, the Biden administration awarded $45 million in funding to MP Materials and the nation’s lone rare earths mine, in Mountain Pass, California. Back in April, the Interior Department approved development activities at the Colosseum rare earths project, located within California’s Mojave National Preserve. The project, owned by Australia’s Dateline Resources, will potentially become America’s second rare earth mine after Mountain Pass. 

Meanwhile, several recycling startups are extracting rare earths from e-waste. Illumynt has an advanced process for recovering them from decommissioned hard drives procured from data centers. In April, hard drive manufacturer Western Digital announced a collaboration with Microsoft, Critical Materials Recycling and PedalPoint Recycling to pull rare earths, as well as copper, gold, aluminum and steel, from end-of-life drives.

Canadian-based Cyclic Materials invented a process that recovers rare-earths and other metals from EV motors, wind turbines, MRI machines and data-center e-scrap. The company is investing more than $20 million to build its first U.S.-based facility in Mesa, Arizona. Late last year, Glencore signed a multiyear agreement with Cyclic to provide recycled copper for its smelting and refining operations.

Another hot feedstock for e-waste recyclers is end-of-life lithium-ion batteries, a source of not only lithium but also copper, cobalt, nickel, manganese and aluminum. Those materials are essential for manufacturing new EV batteries, which the Big Three automakers are heavily invested in. Their projects, however, are threatened by possible reductions in the Biden-era 45X production tax credit, featured in the new federal spending bill.

It’s too soon to know how that might impact battery recyclers — including Ascend Elements, American Battery Technology, Cirba Solutions and Redwood Materials — who themselves qualify for the 45X and other tax credits. They might actually be aided by other provisions in the budget bill that benefit a domestic supply chain of critical minerals as a way to undercut China’s dominance of the global market.

Nonetheless, that looming uncertainty should be a warning sign for e-waste recyclers, said Sinha. “Be careful not to build a recycling company on the back of one tax credit,” he said, “because it can be short-lived.”

Investing in recyclers can be precarious, too, Sinha said. While he’s happy to see recycling getting its due as a meaningful source of supply, he cautions people to be careful when investing in this space. Startups may have developed new technologies, but lack good enough business fundamentals. “Don’t invest on the hype,” he said, “but on the fundamentals.”

Glencore, ironically enough, is a case in point. It has invested $327.5 million in convertible notes in battery recycler Li-Cycle to provide feedstock for its smelter. The Toronto-based startup had broken ground on a new facility in Rochester, New York, but ran into financial difficulties and filed for Chapter 15 bankruptcy protection in May, prompting Glencore to submit a “stalking horse” credit bid of at least $40 million for the stalled project and other assets.

Even so, “the current environment will lead to more startups and investments” in e-waste recycling, Sinha said. “We are investing ourselves.”
