Highlights

• Less than 1% of rare-earth magnets currently come from recycled sources.
• Major initiatives are rapidly scaling circular supply chains:
  • Attero's 100-fold capacity expansion in India
  • Apple's $500M partnership with MP Materials
  • Europe's 25%-by-2030 mandate
• Three key recycling technologies are emerging:
  • Hydrogen decrepitation for magnet-to-magnet loops (HyProMag, Noveon)
  • Hydrometallurgy/pyrometallurgy for chemical extraction (Phoenix Tailings, Cyclic Materials)
  • Advanced separation methods using ion-exchange and bio-adsorbents (ReElement, national labs)
• Despite promising pilot successes and 5-10× increased government funding since 2020, scaling remains challenged due to:
  • High costs compared to virgin ore
  • China's refining dominance
  • The need for billions in new processing infrastructure
• Recycling is considered a strategic hedge rather than a complete supply solution.

Demand for neodymium-iron-boron (NdFeB) magnets and other rare-earth–intensive components is soaring (EVs, wind turbines, electronics), yet barely any come from recycled sources. Experts estimate roughly 1% of all rare-earth magnets are currently produced from recycled material – in the U.S. the figure is under 1%. Almost all spent magnets (and other REE‐bearing scrap) still end up as landfill or low-grade scrap. This reliance on fresh feed – dominated by Chinese mining and refining (60–90% of global output) – has spurred governments and companies worldwide to jump-start a circular REE supply chain.

Major initiatives and investments are underway.

In India, e-scrap processor Attero won government backing (₹1 billion) to ramp rare-earth recycling from 300 t/yr to 30,000 t/yr by 2027. Using a patented process, Attero reports 98% recovery of Nd, Pr, Dy, etc. from electronics. In Europe and North America, multibillion‐dollar partnerships have formed. For example, Apple announced a $500 million multiyear deal with MP Materials (U.S.) to buy domestically‐made NdFeB magnets – combined with building a dedicated recycling line leveraging the value chain sources upstream at Mountain Pass, CA.

MP Materials will use recycled magnet feedstock in its Texas magnet plant (Independence facility) starting ~2027—see MP Materials (opens in a new tab). Similarly, HyProMag (a spinout from U. Birmingham) is partnering with U.S. e‐waste firm Intelligent Lifecycle Solutions to supply NdFeB magnets recovered from hard‐drive scrap. Their joint venture (opens in a new tab) will operate a Texas plant (Dallas–Fort Worth) processing ~~750 tonnes/yr of NdFeB magnets within a few years. ReElement Technologies continues to secure funding from defense and other sources as it plans to scale out.

The promising startup Phoenix Tailings (opens in a new tab) recycles rare earth elements through a proprietary process that extracts metals from mining waste (tailings) and other sources. The company uses a zero-waste, zero-emissions process that involves using recyclable solvents to collect metals and then processing them in a molten salt mixture with electricity. REEx has highlighted this venture as a promising contribution to U.S. rare earth resilience.

Across the Atlantic, Europe’s REE recycling is gathering pace under new policy mandates. The EU’s Critical Raw Materials Act requires 25% of key magnet materials to come from recycling by 2030 (opens in a new tab). That has spurred projects like CREEM (CirculaREEconomy, a £11M UK consortium led by Ionic Technologies) to recover magnets from end‐of‐life EVs and electronics. Participants include metal recycler EMR (Northern England) and automakers (Ford, Bentley, Wrightbus), aiming to build “efficient, scalable” loops.

In Italy, startup RarEarth just raised €2.6M (opens in a new tab) to build the country’s first NdFeB magnet factory from recycled e‑motor waste. On the investor side, OEMs and miners are funding the space: for example, Jaguar Land Rover and BMW invested in Canada’s Cyclic Materials, and DOE/DoD has backed U.S. firms (Maginito/HyProMag, Noveon/Urban Mining Co.) with grants and loans. (A recent DOE-funded study even engineered a 3D “graphene sponge” to capture REEs from shredded e-waste.).

New recycling technologies are emerging in three broad categories

Hydrogen decrepitation (“magnet‐to‐magnet”)

Injecting H₂ gas to crack sintered NdFeB magnets into powder without strong chemicals. This preserves alloy integrity. Leaders include HyProMag (UK→US), Noveon (USA, ex-Urban Mining Co.) and Hitachi Metals (Japan). (HyProMag’s hydrogen-processed powder reportedly matches new‐magnet grades, offering >90% energy savings.)

Hydrometallurgy/pyrometallurgy

Chemically or thermally breaking magnets into oxides. Again, the U.S. firm Phoenix Tailings uses an acid-free leach and molten salt electrolysis to recover REEs from mining and industrial waste, aiming to scale from pilot (200 t/yr) to thousands of tonnes. Canadian Cyclic Materials deploys multistage leaching for EV motors and electronics (with >90% REE recovery).

European players like Solvay and Umicore recycle polishing powders, magnets scrap, and spent catalysts to reclaim Ce, La, Nd, Dy etc. (Osram/ams is working on lamp phosphors.)

Advanced separation

Novel approaches like ion‐exchange, membrane extraction or bio‐adsorbents to concentrate REEs from mixed waste. U.S. startups ReElement Tech (ion‑chromatography) and REEcycle (electrochemical separation) are piloting these methods, as are national labs (Oak Ridge, Ames) exploring membrane/solvent extraction per REEx.

Challenges and Outlook

Scaling is still hard. High costs of recycling vs. cheap virgin ore, mixed waste streams, and technical hurdles mean most scraps are not yet economical. Chinese dominance in refining remains a bottleneck: Western analysts caution that “no near-term substitute” exists for China’s processing capacity. In practice, recycled material will still need downstream refining. Governments are stepping in – e.g., the U.S. DOE has boosted critical‐minerals recycling funding 5–10× since 2020 as cited by REEx – but building new separators and smelters takes years. There are also contamination issues (coatings, mixed chemistries) that drive innovation in “design for disassembly”.

Conclusion

The rare-earth recycling sector is accelerating, with dozens of startups and projects worldwide. Companies report pilot successes in creating “magnet‑to‑magnet” loops and recovering REEs from diverse waste streams (opens in a new tab) such as REEMAG (opens in a new tab).  But meeting demand will require more feedstock from today’s scrap piles, sustained and extensive investment, and critically, new refining capacity (and this will need to be subsidized our models suggest). For now, recycling is seen as a strategic hedge—not yet a complete solution—to global supply risks.
