Resource Circulation Technology Research Team
We seek to develop high-efficiency and environmentally friendly recovery technologies for critical metals that are indispensable for producing lithium-ion secondary batteries (LIBs), rare-earth magnets, catalysts, and other products.

Research themes
- Simple rare-earth magnet recycling process
- Recovery of rare-earth elements (REEs) from unconventional sources
- New critical metal recovery process from waste LIBs
- Highly efficient technologies to recover platinum group metals

Research Team Leader / Greetings
OISHI Tetsuo
The importance of highly efficient metallurgical and recycling processes is growing even more important owing to the recent changes in international trends toword decarbonization and a circular economy. Our reserach team will contribute to the elimination of metal resource constraints in a zero emission society by establishing processes that can be put to practical use.
