New Iwaki Plant

Iwaki Plant,
A New Base for LiB Recycling business.

Note: The New Iwaki Plant is scheduled for completion in 2026.

Fukushima Prefecture - a place where advanced technologies gather

Since the Great East Japan Earthquake in 2011, Fukushima Prefecture has been working to restore industry in areas lost to the earthquake and nuclear disaster. Fukushima Prefecture is putting together advanced technologies as well as research and collaborating with local companies in energy and the environmental fields and other fields to build a new industrial base.
Asaka Riken has been making a significant contribution to this effort. We have actively promoted research and development of minor metals and rare metals recycling at the Iwaki Plant Production Technology Development Center established in 2014. We are promoting our LiB recycling business through introducing new equipment at our Iwaki Plant.

  • History of the Iwaki Plant

  • Former Iwaki Plant

  • Our Iwaki Plant and Production Technology Development Center together serve as a research and development base for recycling minor metals and rare metals. From the time of its completion, the plant began joint research with the Japan Atomic Energy Agency (JAEA). It has begun full-scale research and development activities, including emulsion flow method demonstration experiment. We have also succeeded in recovering rare metals from optical lens waste and increasing its purity through demonstration experiment for the commercialization of lanthanum and gadolinium refining.
    We have acquired many patents related to minor metal recovery and regeneration technologies that we have cultivated through repeated joint research and demonstration testing. We continue to actively acquire patents. Our LiB recycling business is a business that utilizes the minor metal recycling technology and know-how we have accumulated to date.

    Note: Information current as of 2021.

Introducing Research Results to the Iwaki Plant

  • We are currently in the process renovating the Iwaki Plant and introducing a mass production plant for our LiB recycling business.The chemical circulation process we are introducing was developed by our company and is characterized by the fact that once chemicals and water have been used, they can be recycled and circulated within the process and used repeatedly.
    We believe that this is a competitive advantage because it enables us to significantly reduce CO₂ and wastewater emissions, thereby reducing the burden on the environment, and at the same time, it leads to cost reductions.We are also working to improve the efficiency of factory operations and reduce manpower by operating factories 24 hours a day and automating some processes.
    By making the process energy efficient and building a recycling process that produces as little waste as possible, in the future we intend to expand the plant modeled after the Iwaki plant to other plants in Japan and overseas, and challenge the creation of a system to recover rare metals from used LiBs within those regions.

Beyond The Realization of "LiB to LiB"

Since 2013, we have continued to conduct demonstration experiments in the rare metal business.
The skills we have accumulated through many failures and successes has been applied to the LiB recycling business, which is about to grow into the fourth pillar of our business, joining the three pillars of precious metals, environmental business, and systems business that support our company.
We aim to become a leader in the field of regeneration of precious metals and “LiB to LiB,” and to realize a new resource recycling model.
