Metallium Validates 12-Hour Flash Joule Heating Reactor Run Ahead of Multi-Reactor Scale-Up
Event summary
- Metallium completed a 12-hour continuous Flash Joule Heating (FJH) reactor run at its Texas facility on May 12, 2026.
- The test validated operational stability, automation systems, and repeatability for its Generation-1 reactor technology.
- The success reduces technical and operational risks ahead of planned multi-reactor operations at its first commercial facility.
- Flash Joule Heating is being commercialized as an e-Waste processing platform for low-carbon, high-efficiency metal recovery.
The big picture
Metallium's successful 12-hour reactor run is a critical step in scaling its Flash Joule Heating technology for e-Waste processing. The U.S. focus on domestic critical mineral supply chains positions Metallium's low-carbon approach as strategically important. The company's modular parallel-reactor architecture allows for flexible throughput expansion, aligning with growing industrial demand for sustainable metal recovery solutions.
