Research

We are engaged in the research and development of highly efficient production and recycling processes for non-ferrous metals. We are contributing to the development of advanced technologies by producing low-cost and high-purity (high-functionality) metals and materials through highly efficient processes designed based on physical chemistry and electrochemistry. We also aim to realize a sustainable society by developing innovative processes that actualize resource recycling. Major R&D projects are as follows:

  1. Development of smelting and recycling processes for precious metals
  2. Development of recycling process for titanium scrap
  3. Development of smelting and recycling processes for reactive metals
  4. Development of new plating technology
