In Simple Terms
Two companies plan to build a facility in Penang that will recover valuable metals from used industrial materials and electronics. It is expected to start work in April 2029 and make very pure gold for manufacturers. The project could help keep more useful materials in circulation, but its eventual output and impact are not yet known.
A Joint Venture With Defined Shares
Japan’s TANAKA PRECIOUS METAL TECHNOLOGIES and Malaysia’s MEP Enviro Technology have announced plans to establish a joint venture to process recovered materials and extract precious metals. The facility is planned for the Batu Kawan Industrial Park in Penang and is scheduled to begin operations in April 2029. It would give Malaysia local capacity to analyze materials that have already undergone preliminary processing, refine gold, and manufacture metal products for the electronics and semiconductor industries.
The new company will be called TANAKA MEP REFINERY SDN. BHD. Its ownership is clearly divided: TANAKA will hold 66.7%, while MEP will own 33.3%. The arrangement brings together the industrial precious-metals expertise of a Japanese company and a Malaysian partner focused on resource recovery. The chosen site in Batu Kawan places the facility in a Malaysian industrial zone, rather than locating the refining stage far from the country’s industrial activity.
According to the announced plans, the project will do more than melt raw material and produce a finished metal. Its activities will include analyzing recovered materials, refining precious metals, manufacturing products, and importing, exporting, and selling them. The company is also expected to trade, lease, and store precious-metal bullion. Together, these activities would create a business chain that spans the inspection of incoming materials and the handling of finished metal products.
A Facility Under Construction, With Operations Still Years Away
A groundbreaking ceremony was held at the planned site on October 8, 2026. Representatives of both companies attended, along with officials and public figures from Penang. They included the state’s governor, Tun Dato Seri Utama Haji Ramli bin Ngah Talib; Chief Minister Chow Kon Yeow; Japan’s Consul-General in Penang, Shinya Machida; and other government officials. The ceremony marked the move from technical cooperation to construction, but it does not mean the facility has begun production.
The plan sets April 2029 as the target date for operations to begin. That gap makes this a long-term industrial project, not an immediate expansion of metal production. Until then, the activities described remain goals for the new facility. The published information gives no figure for production capacity, the volume of material it will process each year, or the number of people expected to work there. Its likely output and market share therefore cannot be estimated from the announcement alone.
Why Precious Metals Are Being Recycled
Malaysia and other countries in the Association of Southeast Asian Nations (ASEAN) are home to semiconductor, electronics-component, and other manufacturing industries. These processes can generate leftover materials containing precious metals, creating an opportunity to recover them instead of treating them as worthless waste. Recovery becomes especially worthwhile when the metals can be separated and processed, allowing them to return to industrial use after inspection and refining.
Electronics that have reached the end of their useful life—often called e-waste—are another type of material that needs appropriate handling. Discarded devices do not simply disappear when people stop using them; they need to be managed through systems that recover whatever can be reused. Stricter environmental rules and growing interest in recycling resources are encouraging countries and regions to process this waste where it is generated. In that context, the project connects manufacturing leftovers with the need to manage recovered resources locally.
Recycling does not mean that every recovered material automatically becomes metal ready for manufacturing. Materials can differ in composition, which is why the facility’s plan includes analyzing them before refining. This step matters in practice because it helps determine what the preprocessed materials contain and supports the choice of an appropriate recovery process. The announcement lists analysis as one of the company’s activities, alongside refining and manufacturing, but does not disclose the equipment or processing methods it will use.
4N Gold and Products for Industry
In its initial phase of operations, the company plans to produce 4N gold, meaning gold with a purity of 99.99%, as well as potassium gold cyanide, known by the abbreviation PGC. The 4N label describes the metal’s purity: the four nines indicate a gold content of 99.99%, leaving only a very small proportion of other materials. This is a stated specification for planned initial production, not a result the facility has achieved.
The initial products are intended for the electrical and electronics industries, as well as the semiconductor industry. That focus reflects the facility’s connection to industrial demand for metal materials, rather than simply trading gold as an investment bar or general commodity. Potassium gold cyanide is included in the planned product list for these industries, but the announcement does not specify production volumes or the particular applications for which it will be used. Nor does it say whether the product range will change after the initial phase, so the confirmed starting focus remains high-purity gold and PGC.
Cooperation That Predates the Facility
The partnership did not begin with the groundbreaking ceremony. In August 2024, TANAKA and MEP signed a technical assistance agreement on precious-metal recovery, and they have worked together since then to support precious-metal recycling in Malaysia. The new project gives that cooperation a formal institutional base: rather than limiting their work to technical assistance, the companies now plan to establish a business responsible for analysis, refining, manufacturing, and handling the resulting products.
Under the plan, the facility will receive recovered materials that MEP has already preprocessed. The joint venture will then analyze those materials, refine the precious metals, manufacture products, and sell, import, or export them. It is important to distinguish the preliminary processing that will take place before the materials reach the facility from the analysis and refining that will be carried out as part of the new company’s work. The project divides responsibilities across a metal-recovery chain; it is not a single process that starts with mixed waste and ends directly with a finished product.
Expertise and Quality in a Local Supply Chain
According to TANAKA, the partnership draws on its long experience in refining and processing precious metals, along with its accumulated expertise in quality control, production management, and related fields. The aim is to combine those capabilities with MEP’s resource-recovery work and establish an integrated precious-metal recycling pathway within Malaysia. Here, integration means linking several stages, from receiving and analyzing preprocessed materials to refining them and preparing industrial products.
Quality control is particularly important for a project aiming to produce gold to a specified purity. The value of an industrial product depends on its specifications and consistency, not merely on whether it contains gold. Production management also links the materials coming into the facility with the products it can make. However, the partners have not disclosed inspection procedures, quality-control standards, or traceability systems. What can be confirmed is that these areas of expertise will form part of the model the companies aim to build—not that a detailed operating system has already been implemented.
One Link in a Wider Recycling Network
TANAKA is developing an international network for precious-metal recovery and refining, with facilities in Japan, Europe, North America, China, Taiwan, and other regions. The planned Malaysian facility would extend that presence into Southeast Asia and strengthen the company’s operations in ASEAN. From the company’s perspective, a regional footprint can help establish channels for recovering and reusing resources while supporting the stability of precious-metal supplies.
The announcement does not suggest that the new facility will replace or make the existing network unnecessary; instead, it presents it as an addition to a broader system. Expanding recycling capacity will not eliminate the need for sources of metals, but it creates an opportunity to recover some of the material already used in industrial processes and electronic products. For Malaysia, the stated significance is the creation of a local framework linking recovered materials to refining and industrial products, rather than treating recovery as a step separate from manufacturing supply chains.
What Has Not Yet Been Disclosed?
Although the partners have identified the site, ownership shares, initial products, and target start date, the announcement provides no figures for the investment or the facility’s processing capacity. It also does not say how much gold the plant may produce, how much waste it will receive, or how much it is expected to reduce waste or increase metal supplies. At this stage, it is therefore not possible to measure the project’s contribution to Malaysia’s market or to the region’s supplies.
These gaps will matter when the project’s results are assessed. In practice, the success of a recycling facility will depend on a steady supply of suitable materials, its ability to analyze and process them, and whether its products meet the specifications industrial customers need. These factors should be evaluated once operating data are available, not assumed in advance. For now, the confirmed facts are that the companies have launched the project’s development, selected a site in Penang, set a target start date, and included 99.99% pure gold and PGC in their initial production plans.
The Bottom Line
The TANAKA–MEP project is an attempt to build an integrated Malaysian pathway for recovering and refining precious metals, using materials generated by electronics manufacturing and addressing the need to process e-waste locally. TANAKA will own 66.7% of the joint venture and MEP 33.3%. The facility is planned for Batu Kawan in Penang, with operations targeted to begin in April 2029. Its plans include analyzing and refining recovered materials and manufacturing metal products, starting with 4N gold—99.99% pure—and potassium gold cyanide. The project extends the technical-assistance agreement begun in August 2024 and adds a Malaysian site to TANAKA’s global recycling network. Its actual output and impact will depend on operating data that have not yet been announced.
