Ahead-looking: Western Digital has launched a large-scale onerous disk drive recycling initiative in partnership with Microsoft, Crucial Supplies Recycling, and PedalPoint Recycling. This system, referred to as the Superior Recycling and Uncommon Earth Materials Seize Program, goals to deal with a longstanding downside within the tech trade: the lack of precious uncommon earth components and different vital supplies when information heart drives attain the tip of their lifecycle and are usually destroyed, producing vital e-waste.
Though solid-state drives have turn into the usual for private computer systems, mechanical onerous drives stay the spine of knowledge facilities worldwide. When these drives are retired, they’re typically shredded for information safety, and their parts – starting from aluminum and metal to uncommon earth magnets – incessantly find yourself in landfills.
The environmental value is additional compounded by the truth that mining new uncommon earth components comparable to dysprosium, neodymium, and praseodymium is extremely energy-intensive and produces substantial greenhouse fuel emissions. Including to the problem, China, which dominates world uncommon earth materials manufacturing, has just lately imposed export restrictions on a number of key supplies, threatening the availability chain for US know-how firms.
Western Digital’s program goals to reclaim vital supplies domestically. The method begins with gathering end-of-life drives from Microsoft’s US information facilities, that are then shredded and sorted by PedalPoint Recycling. The extracted magnets and metal are despatched to CMR, the place an acid-free dissolution recycling know-how recovers uncommon earth components. This copper salt-based course of selectively leaches out uncommon earth oxides with outstanding purity (as much as 99.5 %) whereas avoiding the cruel chemical substances that may injury uncommon earths and different precious metals like aluminum.
The pilot program has already diverted roughly 47,000 kilos of onerous drives, SSDs, and mounting caddies from landfills or much less efficient recycling streams. In keeping with Western Digital, the method has recovered over 90 % of the uncommon earth components and about 80 % of all shredded materials by mass.
The environmental advantages are substantial. A life cycle evaluation cited in Western Digital’s whitepaper estimates that the brand new course of generates 95 % fewer greenhouse fuel emissions than conventional mining and refining strategies. By holding the whole uncommon earth oxide manufacturing course of inside the USA, the initiative additionally reduces transportation emissions and strengthens the resilience of the home provide chain.
Microsoft, which supplied the preliminary batch of drives for this system, sees this as a vital step towards a extra round financial system in tech. “HDDs are very important to our information heart infrastructure, and advancing a round provide chain is a core focus for Microsoft,” stated Chuck Graham, the corporate’s company vp for cloud sourcing, provide chain, sustainability, and safety. “This pilot program has proven {that a} sustainable and economically viable end-of-life administration for HDDs is achievable.”
The know-how behind the recycling course of was initially developed on the Crucial Supplies Innovation Hub at Ames Nationwide Laboratory and has been scaled from lab to demonstration in simply eight years.
The potential affect of this program is huge. In keeping with the Monetary Occasions, there have been 23,000 information facilities housing 70 million servers in 2022 – every containing a number of onerous drives that usually final solely three to 5 years. In the meantime, world e-waste is projected to achieve 75 million tons by 2030.
“Western Digital is at present increasing the HDD uncommon earth materials seize program primarily based on the profitable pilot with Microsoft,” Jackie Jung, WD’s VP of world operations technique and company sustainability, told Tom’s {Hardware}. “This program is now in growth with numerous our hyperscale prospects.”
