About PHNX Materials:

PHNX Materials addresses the dwindling supply of fly ash - a key ingredient in concrete - by refining 23 billion tons of landfilled coal ash into ASTM-grade fly ash and critical metals. Our cost-effective, scalable technology delivers a triple win: helping utilities manage coal ash (a waste stream four times larger than plastic), providing concrete companies a cheaper and greener alternative to cement, and supplying industries with domestic sources of aluminum, rare-earth elements and titanium. Founded by Stanford and Tesla alumni, PHNX is on a mission to mine this abundant domestic natural resource.
