Rare earth magnet recycling in Japan is moving from concept to industrial execution, with Daikin Industries, Shin-Etsu Chemical, Hitachi, and Tokyo Eco Recycle launching what Daikin describes as Japan’s first circular scheme to recover rare earth magnets from compressors used in commercial air conditioners. The group plans to develop automated recovery equipment in 2026 and begin full-scale operations in 2027, using AI image recognition, robotics, and centralized data management to improve recovery efficiency and traceability.
From Used Compressors to New Magnets
Under the scheme, Daikin will collect compressors removed during repair and overhaul work, while Tokyo Eco Recycle will handle disassembly, demagnetization, and magnet extraction with support from Hitachi. Shin-Etsu Chemical will then use the recovered material to manufacture new rare earth magnets, creating a closed-loop process from collection to remanufacturing. Daikin said the effort is meant to fill a gap in Japan’s recycling system because commercial air conditioner compressors have not had an established recycling framework comparable to household appliances.
The market relevance goes well beyond air conditioning. Rare earth magnets are essential for high-efficiency motors used in HVAC systems, electric vehicles, electronics, and industrial equipment. That makes recycling increasingly important as supply chains stay heavily concentrated. According to the IEA, China accounts for around 60% of mined magnet rare earth supply, more than 90% of refining, and almost 95% of permanent magnet production, leaving manufacturers exposed to supply and policy risks.
Why This Matters for Japan’s Supply Chain Strategy
This initiative also stands out because it combines existing industrial capabilities rather than starting from zero. Shin-Etsu has said it has recycled magnet powder since 2007 and expanded that work to rare earth magnets from end-of-life products since 2013, giving the project a stronger technical foundation for scale-up. At the policy level, Japan’s environment ministry has proposed ¥37.9 billion in its fiscal 2026 budget to strengthen recycled-material supply chains, including projects involving rare metals and rare earths such as neodymium.
For the wider market, the Daikin-led program is important because it links automation, recycling, and economic security in one model. If automated disassembly and magnet recovery can work efficiently across different compressor models, Japan could build a more reliable secondary supply of rare earth magnet material while reducing import dependence in strategically sensitive industries.
SuperMetalPrice Commentary
This is more than a recycling pilot. It is an early industrial blueprint for how Japan can turn installed equipment waste into a domestic source of strategic magnet materials. The next milestone to watch is whether the model expands beyond Daikin’s compressor base and begins supplying meaningful recycled feedstock into Japan’s broader rare earth magnet market.
