We are PHNX Materials. We’re turning America’s coal ash waste into tomorrow’s critical solutions. Across the U.S., 2.9 billion tons of landfilled coal ash sit idle. At PHNX, we see this not as waste, but as one of the largest untapped industrial resources of our time. With our proprietary, chemistry-driven process, we reclaim, refine, and reinvent this ash—producing ASTM-grade fly ash for concrete, critical metals like aluminum and rare earths, and key chemicals for American manufacturing. We’re not just reducing emissions—we’re rebuilding infrastructure and reshaping supply chains scalably, economically, and immediately.

About us
Transforming America’s most overlooked waste into tomorrow’s essential materials. Across the United States, 2.9 billion tons of coal ash lie dormant in landfills—contaminated with sulfur, leaching into groundwater, and largely untouched for decades. At PHNX Materials, we see this not just as a challenge, but as a once-in-a-generation opportunity. PHNX is the only industrial technology company with a validated, scalable process to unlock the full value of this vast domestic resource. Using our proprietary, chemistry-driven platform, we reclaim, refine, and reinvent landfilled coal ash into strategic, high-performance industrial inputs. Our process yields: - ASTM-grade fly ash to strengthen concrete and rebuild infrastructure - Strategic metals like aluminum and rare earth elements - Critical chemical compounds that enable domestic manufacturing. By turning waste into essential materials, PHNX is powering a cleaner, more resilient industrial base—reducing carbon emissions, revitalizing infrastructure, and reshoring critical supply chains. Our technology is not just visionary—it’s tested, cost-effective, and ready to scale. We’re building a future where infrastructure is stronger, materials are cleaner, and waste is no longer wasted.
