PHNX Materials Information

America's critical metals aren't buried. They've already been dug up. 4.6 billion tons of domestic industrial waste contains over 1,000 years of domestic gallium, germanium, silicon, and rare earth elements. PHNX Materials is the only company that extracts critical metals from industrial waste while selling the residual waste into concrete. No acid leaching. No waste-for-waste tradeoff. We deliver domestic gallium, germanium, and silicon for semiconductors and defense. ASTM-grade supplementary cementitious material for infrastructure. And fertilizer as a co-product, not a cost center. Backed by the Department of Energy and the Defense Logistics Agency, PHNX has identified 850+ U.S. sites, worked with 25+ partners, and brings an exceptional team of engineers from Stanford and U.S. national labs. We're building a domestic supply chain without waiting decades for new mines.
