SUN METALON

SUN METALON, a Japanese-American deep-tech startup founded in 2021, is positioned to address the decarbonization and circular supply chain challenges within the metal industry. The company was co-founded by CEO Kazuhiko Nishioka, a former engineer at Nippon Steel who conceived of the technology while pursuing his PhD in Materials Science at Northwestern University. He and his co-founders, Kei Takizawa, Yuki Maeda, and Koji Kageyama, launched the company to revolutionize how industrial metals are processed and reused.

The firm's core business revolves around a proprietary heating technology that cleans and recycles low-value metallic waste, such as machining chips, grinding swarf, and sludge. This process utilizes electromagnetic energy and a special heating booster to heat contaminants like oil and fluid without fully melting the base metal, significantly reducing energy consumption—by as much as 85% compared to conventional methods. The technology, which is protected by patents in the U.S. and Japan, is entirely electric-powered, enabling a zero-emission process when paired with renewable energy sources.

SUN METALON operates on a B2B model, targeting clients in the automotive, construction machinery, heavy industry, and steel manufacturing sectors. It provides modular, oven-like units, such as the Venus-L, that can be integrated directly onto a factory floor. These systems convert contaminated metal scraps, which might otherwise be sent to a landfill at a cost, into dense, clean metal pucks that retain their original alloy chemistry. This allows clients to reintroduce the material into their production as high-quality recycled feedstock, creating value from a waste stream. The company has already established partnerships with industry leaders like Toyota for aluminum recycling.

Financially, SUN METALON has attracted significant investor interest, having raised a total of $30.7 million as of its Series A round in late 2024. This funding, supported by investors such as JIC Venture Growth Investments, UTEC, and Globis Capital Partners, is being used to expand its U.S. operations, which includes a pilot and demonstration facility near Chicago, and to scale the deployment of its technology with client companies.
