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 new equipment at the Iwaki Plant to realize "LiB to LiB"

  • We are currently in the process renovating the Iwaki Plant and introducing a mass production plant for our LiB recycling business with an investment of approximately one billion yen.
    The new facility will enable efficient recovery of minor metals from the raw materials produced during pyrometallurgy using hydrometallurgy.
    The recycling process is characterized by the idea that once the chemicals are used, they can be recycled and circulated in-house. The process is partially automated and performed 24 hours a day. This allows for greater efficiency and labor savings at the plant.
    The plant is working to create a recycling process that is energy efficient and minimizes waste and reduce its environmental impact and gain a competitive advantage through cost reductions.
    We intend to develop plants with the Iwaki Plant as a model plant in Japan and overseas to create a system for recovering minor metals locally at each plant.

    Note : The total investment into the Iwaki plant is expected to be approximatery 2.2 billion yen, as of 2023.

Next Story

Local Production and Consumption + Local Regeneration

We have conducted various experimental tests beginning from 2013 while experiencing repeated successes and failures before entering the LiB recycling business.
The LiB recycling business may become our fourth pillar in addition to the three pillars of precious metal business, environment business, and software business. In addition to restructuring our business portfolio, we aim to become a leader in the fields of precious metals and "LiB to LiB", and realize a new resource recycling model: "Local production and Consumption + Local Regeneration"
