Social system design and assessment methods for a zero emission society
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.

Resource Circulation Technology Research Team

Research themes

  • Establishment of a simple rare-earth magnet recycling process
  • Development of technologies for recovering rare-earth elements (REEs) from nontraditional resources and highly efficient technologies to recover platinum group metals
  • Establishment of a new critical metal recovery process from waste LIBs

Concept for social contributions and implementation

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

NARITA Hirokazu

I have studied the separation of critical metals for many years, and I understand that this field is growing even more important owing to recent changes in international affairs and trends in decarbonization. We 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.
