Tanaka Precious Metal Breaks Ground on Penang Plant to Recycle Gold for Chipmakers

Japan's Tanaka Precious Metal Group marked a milestone on October 8 for a new precious-metals recycling plant in Penang, Malaysia, with a ceremony attended by Penang's Chief Minister, Chow Kon Yeow, and the state's Yang di-Pertua Negeri, Tun Haji Ramli bin Ngah Talib. The facility, operated through a joint venture called Tanaka MEP Refinery, is designed to recover gold and other precious metals from scrap generated during semiconductor and electronic component manufacturing, with an eye toward feeding that recovered material back into the chipmaking supply chain. The plant is targeting an operational start in April 2029.

Why Penang makes sense for this

Penang has spent decades building itself into one of Southeast Asia's most important semiconductor and electronics manufacturing hubs, hosting assembly, testing, and packaging operations for some of the industry's biggest names. A recycling plant that depends on a steady stream of manufacturing scrap containing precious metals needs to sit close to where that scrap is actually generated, which makes Penang a natural location rather than a coincidental one. The move also extends the state's role in the chip supply chain beyond assembly and testing into the materials recovery side of the business.

Gold's quiet but essential role in chips

Gold shows up in semiconductor manufacturing in less visible but important ways, used in bonding wires and connectors that require a metal combining strong conductivity with resistance to corrosion. Recovering that gold from manufacturing scrap, rather than relying solely on freshly mined supply, gives chipmakers an additional, more geographically convenient source of a material that otherwise has to move through longer global mining and refining supply chains. For an industry that has spent recent years increasingly focused on supply chain resilience, a dedicated regional recycling source is a meaningful, if unglamorous, piece of that puzzle.

A long runway before full operation

With a targeted start of April 2029, more than two years out from this month's milestone, the project reflects how much construction, equipment installation, and regulatory work typically sits between an initial ceremony and a fully operating industrial recycling facility. Neither Tanaka Precious Metal Group nor its Malaysian joint venture partner has disclosed investment figures or planned processing capacity for the plant, details that would normally offer a clearer sense of how significant a supply source the facility is ultimately meant to become.

Part of a broader materials story

The Penang plant fits into a wider pattern of chip-adjacent supply chain investment spreading across Southeast Asia, as manufacturers and their material suppliers look to diversify where critical inputs are sourced and processed rather than concentrating that work in a small number of legacy hubs. Whether this specific venture turns into a meaningful supply source for the region's chipmakers, or stays a modest, specialized operation, will likely become clearer only as the 2029 target date approaches and more operational details are disclosed.
