Efficient Recovery of Critical Metals for a Zero Emission Society

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

Concept for social contributions and implementation

Our goal is to establish processes for recycling critical metals from urban mines.

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.

We seek to develop high-efficiency and environmentally friendly recovery technologies for critical metals (e.g., Li, Co, Ni, rare earth elements, and platinum group metals (PGM)) that are indispensable for producing lithium-ion secondary batteries (LIBs), rare-earth magnets, PGM catalysts, and other products.
