Although China’s response to the latest curbs was swift and seemingly strong, experts told Ars that China’s response to Biden’s last round of tariffs was relatively muted. It’s possible that this week’s ban on exports into the US could also be a response to President-elect Donald Trump’s threat to increase tariffs on all Chinese goods once he takes office.
Analysts warned Monday that new export curbs could end up hurting businesses in the US and allied nations while potentially doing very little to block China from accessing US tech. On Tuesday, four Chinese industry associations seemingly added fuel to the potential fire threatening US businesses by warning Chinese firms that purchasing US chips is “no longer safe,” Asia Financial reported.
Apparently, these groups would not say how or why the chips were unsafe, but the warning could hurt US chipmaking giants like Nvidia, AMD, and Intel, the financial industry publication closely monitoring China’s economy forecast said.
This was a “rare, coordinated move” by industry associations advising top firms in telecommunications, autos, semiconductors, and “the digital economy,” Asia Financial reported.
As US-China tensions escalate ahead of Trump’s next term, the tech industry has warned that any unpredictable rises in costs may end up spiking prices on popular consumer tech. With Trump angling to add a 35 percent tariff on all Chinese goods, that means average Americans could also end up harmed by the trade war, potentially soon paying significantly more for laptops, smartphones, and game consoles.

There is the mental image that most people have of electronics recycling, and then there is the reality, which is shredding.
Less than 20 percent of e-waste even makes it to recycling. That which does is, if not acquired through IT asset disposition (ITAD) or spotted by a worker who sees some value, heads into the shredder for raw metals extraction. If you’ve ever toured an electronics recycling facility, you can see for yourself how much of your stuff eventually gets chewed into little bits, whether due to design, to unprofitable reuse markets, or sheer volume concerns.
Traditional hard drives have some valuable things inside them—case, cover, circuit boards, drive assemblies, actuators, and rare-earth magnets—but only if they avoid the gnashing teeth. That’s where the DiskMantler comes in. Garner Products, a data elimination firm, has a machine that it claims can process 500 hard drives (the HDD kind) per day in a way that leaves a drive separated into those useful components. And the DiskMantler does this by shaking the thing to death (video).
Insert the drive into the DiskMantler like you’re nostalgic for the VCR days.

The DiskMantler, using “shock, harmonics, and vibration,” vibrates most drives into pieces in between 8–90 seconds, depending on how much separation you want. Welded helium drives take about two minutes. The basic science for how this works came from Gerhard Junker, the perfectly named German scientist who fully explored the power of vibrations, or “shear loading perpendicular to the fastener axis,” to loosen screws and other fasteners.
As Garner’s chief global development officer, Michael Harstrick, told E-Scrap News, the device came about when a client needed a way to extract circuit boards from drives fastened with proprietary screw heads. Prying or other destruction would have been too disruptive and potentially damaging. After testing different power levels and durations, Garner arrived at a harmonic vibration device that can take apart pretty much any drive, even those with more welding than screws. “They still come apart,” Harstrick told E-Scrap News. “It just takes a little bit.”
Improving the recovery and sorting ease of hard drives is itself a useful thing, but the potential for rare-earth magnet recycling is particularly attractive. Most rare-earth magnet recycling involves “long-loop” recycling, or breaking them down into rare earth elements and then putting those back into the magnet production stream, which is energy-intensive and not very cost-effective. Electric vehicles and wind turbines have huge amounts of rare-earth magnets in them but rarely see recycling. Hard drives, while individually small, are massive in scale, with roughly 259 million shipped in 2021.
One Canadian firm, based on a University of Birmingham-patented process, wants to reuse drive magnets more directly, creating new sources that don’t require extraction and aren’t quite so globally concentrated. That Canadian firm, HyProMag, uses robotics to find and extract drives’ permanent magnets, then sends the rest of the disk off for recycling.
The technology is not all there yet, but soon enough, it looks like something interesting will shake out.
