Recycling Rare Earth Magnets: From Collection to Recovery
Less than 1% of rare earth magnets are estimated to be recycled globally.
Rare earth magnets, especially neodymium-iron-boron (NdFeB) magnets, are critical to EVs, wind turbines, consumer electronics and industrial equipment. Their high magnetic strength enables smaller, lighter and more efficient products.
But supply chains remain highly concentrated, while primary mining and processing can create significant environmental impacts.
Recycling offers another route: recovering rare earth materials from manufacturing scrap and end-of-life products to create a secondary source of supply.
Why does rare earth magnet recycling matter?
Several factors are pushing the industry toward greater recovery of rare earth magnets:
| Driver | Why it matters |
|---|---|
| Supply concentration | Rare earth mining, processing and refining are concentrated in a small number of countries. |
| Growing demand | EVs, wind turbines, electronics and industrial applications continue to require high-performance magnets. |
| Supply disruptions | Export restrictions and other supply bottlenecks can affect access to magnets and rare earth materials. |
| Environmental impact | Primary mining and processing can generate high energy use, waste and pollution. |
| Resource security | Recycling can create a secondary and more geographically diversified source of rare earths. |
Recycling will not replace primary supply, but it can help reduce supply risk and improve resource efficiency.
Where is innovation happening?
The recycling value chain is developing across three main areas:
1. Better waste collection
A reliable supply of magnet-rich feedstock is essential for recycling at scale.
Dedicated collection channels can help recover magnets before they enter mixed waste streams, particularly from products such as hard disk drives, EV motors and other electronic equipment.
Companies are developing new approaches to secure this feedstock, including:
- Western Digital, Microsoft, Critical Materials Recycling and PedalPoint, collecting retired hard disk drives from Microsoft data centers.
- Cyclic Materials, building a U.S. feedstock network for end-of-life magnet components.
- HyProMag USA, developing a hub-and-spoke model to collect and pre-process NdFeB feedstock.
Policy is also pushing collection forward, with measures in the EU, U.S. and UK supporting the recovery of critical materials from end-of-life products.
2. Smarter disassembly
Magnets are often buried inside complex products, making recovery slow and labor-intensive.
Innovation is emerging across the disassembly process:
| Approach | What it enables |
|---|---|
| Smart sorting | Identifies products likely to contain rare earth magnets before teardown. |
| Automated disassembly | Uses robotics and machines to extract magnets at higher speed and consistency. |
| Product identification | Tracks magnet type, location and material composition to support recovery. |
| Design for recycling | Makes magnets easier to identify, access and remove at end of life. |
For example, research has demonstrated ways to sort EV motors for rare earth content without opening them, while automated HDD disassembly systems are already moving toward commercial deployment.
Digital product passports and traceability systems could also make it easier to identify valuable materials before products reach recycling facilities.
3. From waste back to rare earths, or magnets
Recycling technologies broadly fall into two pathways:
| Pathway | How it works | Key advantage |
|---|---|---|
| Long-loop recycling | Breaks waste down into rare earth elements or compounds before producing new materials. | Can process different types of feedstock and produce purified rare earth materials. |
| Short-loop recycling | Recovers the magnet material directly for use in new magnets. | Preserves more of the original material and can reduce processing steps. |
Long-loop recycling
Hydrometallurgy is currently one of the main approaches. It can achieve high recovery and purity but often requires chemical reagents and multiple processing steps.
Other emerging approaches include:
- Ionic liquids
- Membrane separation
- Electrochemical recovery
- Bioleaching
- Pyrometallurgy
- Plasma separation
These technologies aim to improve recovery, reduce chemical use or handle more complex feedstocks, but cost, energy use, scalability and process complexity remain challenges.
Short-loop recycling
Direct recycling aims to turn used magnets back into magnet material with minimal processing.
One of the most developed approaches is Hydrogen Processing of Magnet Scrap (HPMS).
HPMS uses hydrogen to break NdFeB magnets into a reusable powder while retaining much of the original alloy composition. The material can then be used to produce new magnets.
This can reduce the need for strong acids and extensive chemical separation, potentially lowering both processing steps and environmental impacts.
The challenge is that HPMS requires relatively clean, magnet-rich feedstock and effective pre-processing to remove coatings and contaminants.
Policy is starting to push the market
Governments are increasingly treating rare earth magnet recycling as a supply-security issue.
| Region | Key development |
|---|---|
| European Union | CRMA sets a 25% benchmark by 2030 for recycling to meet EU annual consumption of strategic raw materials. |
| United Kingdom | Critical Minerals Strategy targets 20% of annual critical mineral demand from recycling by 2035. |
| United States | DOE announced up to $134M in 2025 for recovering and refining rare earths from waste and other sources. |
| South Korea | Target of 20% recycling for 10 strategic minerals by 2030. |
The EU is also introducing requirements around information and recyclability for products containing permanent magnets.
Industrial programs are supporting this shift. For example, the €13M SUSMAGPRO project developed pilot lines for turning NdFeB scrap into new magnets, while the €7.1M HARMONY project is focused on closed-loop recovery from end-of-life EV motors and wind turbines.
What is holding recycling back?
Despite growing interest, several barriers remain:
- Limited feedstock: Many magnet-containing products have not yet reached end of life.
- Collection: Magnet-rich waste is often dispersed across different products and waste streams.
- Disassembly: Extracting magnets from complex products can be costly and labor-intensive.
- Scale: Many technologies still need to demonstrate consistent commercial-scale performance.
- Economics: Recycling costs can be difficult to justify when primary rare earth prices are stable.
- Quality: Recovered material must meet industrial specifications before manufacturers can use it at scale.
A major challenge is also how the costs and benefits are distributed across recyclers, manufacturers, governments and end users.
The road ahead
Rare earth magnet recycling is still at an early stage, but collection, disassembly and recycling technologies are advancing.
As supply security and resource efficiency become more important, recycling can help build a more resilient magnet supply chain. Explore more on rare earth magnets recycling.
