TOKYO, Nov 13, 2026 – (JCN Newswire via SeaPRwire.com) – Furuya Metal Co., Ltd. (Head office: Toshima-ku, Tokyo; President: Takahito Furuya; “Furuya Metal”) has launched a demonstration trial with Asahi Kasei Corp. (Head office: Chiyoda-ku, Tokyo; President and Representative Director: Koshiro Kudo; “Asahi Kasei”) and Circularise B.V. (Head office: The Hague, the Netherlands; “Circularise”), a company in which Asahi Kasei has invested, to evaluate the feasibility of ensuring traceability for precious metals used in chlor-alkali electrolysis electrodes and issuing Digital Product Passports (hereinafter, “DPP”)*1.
This initiative builds on the “Demonstration Trial Regarding Recycling of Metals for Chlor-alkali Electrolysis Cells and Electrodes” launched in 2025 by Asahi Kasei, Nobian, Furuya Metal and Mastermelt. In addition to the circular utilization of precious metals recovered from end-of-life electrodes, the initiative will digitally track and visualize the origin and circulation history of these metals, with the aim of achieving both circular resource utilization and greater supply chain transparency.
Background
Precious metals such as iridium (Ir) and ruthenium (Ru) are critical minerals used across a wide range of industries, including in chlor-alkali electrolysis electrodes, electronic components and semiconductor materials. Demand is also expected to grow in hydrogen production using proton exchange membrane (PEM) water electrolyzers*2.
However, these precious metals come from limited sources. According to the International Platinum Group Metals Association (IPA)*3, global annual primary iridium production is estimated at around 7 metric tons, and annual ruthenium supply at approximately 30 metric tons. Production is concentrated in a very small number of regions, and most of it is obtained as a by-product of platinum mining. In addition to these supply constraints, rising demand and growing price volatility in recent years have heightened the importance of securing a stable supply of these resources and using them effectively. As a result, there is growing interest in recycling precious metals recovered from end-of-life products and using them as circular resources.
Even if the sources of end-of-life cells and electrodes and the refiners of the recovered metals are known, tracking the distribution routes between these stages and determining how the metals are reused after refining remains challenging. To make appropriate circular use of recovered precious metals, it is important to have a mechanism that connects information from recovery through to reuse.
Furthermore, in recent years, properly tracking and managing the origin and circulation history of recycled materials has come to support their quality assurance and greater supply chain transparency. Mechanisms for sharing such information are expected to support responsible mineral sourcing, promote resource recovery, and help companies meet the requirements of sustainability certifications.
Key Details of the Demonstration Trial
In this demonstration trial, Furuya Metal, which has extensive expertise in the refining, processing, and recycling of Ir and Ru, will collaborate with Asahi Kasei to evaluate the feasibility of establishing traceability and issuing DPPs for the circular utilization of precious metals in chlor-alkali electrolysis electrodes. The trial will use proprietary technology from Circularise, which has provided supply chain traceability and data-sharing solutions in Japan and around the world for about 10 years. The technology allows only the necessary information to be shared across the supply chain while protecting companies’ confidential information.
Between February and September 2025, Asahi Kasei and Circularise conducted an initial proof of concept using a simulated scenario. They verified whether data such as the amount of metal recovered from end-of-life electrodes and the amount reused in new electrodes could be managed on the Circularise platform and confirmed key aspects of feasibility. In the current trial, Furuya Metal will participate as an external partner, and verification will be conducted on actual recovery and recycling processes.
The trial will proceed in the following phases:
Phase 1: Verify methods for obtaining, recording, and managing traceability information across the process from the collection of end-of-life electrodes through precious metal extraction and refining to the production of recycled metal*4.
Phase 2: Evaluate the feasibility of a mechanism for sharing information on circular resources and the issuing DPPs throughout the process, from recycled metal to the manufacture of new electrodes.
Based on the insights gained in each phase, the companies will explore the practical implementation of a system that makes the circulation history of recycled precious metals visible.
Outlook
Going beyond conventional recycling, this trial aims to enhance the value of circular resources by making visible “what resources have been circulated, and through what routes.”
Through this initiative, Furuya Metal will advance precious metal recycling and greater supply chain transparency in the chlor-alkali field. Looking ahead, with an eye toward expanding into water electrolysis for hydrogen production, Furuya Metal will work to build mechanisms that achieve both circular use and traceability across the various industries that depend on critical minerals, thereby contributing to the promotion of strategic circular use and the realization of a sustainable, resource-circulating society.
*1 Digital Product Passport (DPP): A mechanism for digitally recording and sharing information on a product’s raw materials, manufacturing, recycling, and other aspects. It helps identify the origin and history of products and resources, contributing to greater supply chain transparency and the circular use of resources.
*2 PEM water electrolyzer: A device that produces hydrogen and oxygen by electrolyzing water, using as its electrolyte a solid polymer membrane that conducts hydrogen ions (proton exchange membrane).

About Furuya Metal Co., Ltd.
Furuya Metal manufactures industrial precious metal products from highly rare precious metals belonging to the platinum group metals (PGMs), such as platinum (Pt), iridium (Ir) and ruthenium (Ru). Because these precious metals are extremely difficult to process, only a limited number of industrial precious metal manufacturers worldwide specialize in PGMs. With excellent properties such as heat resistance, chemical stability and high electrical conductivity, industrial precious metals, PGMs in particular, are materials with an important mission: supporting the development of fields including electronics, optical glass, clean energy, the environment and medicine.
Specializing in PGMs, which have particularly outstanding properties among precious metals, Furuya Metal manufactures and sells industrial precious metal products such as crucibles (heat-resistant containers), thin-film materials, thermocouples (temperature measurement devices) and compounds. The company also engages in recycling businesses, including refining and recovery, to make effective use of rare precious metal resources.
