By turning coal plant waste streams into one of North America's largest supplies of fly ash and bottom ash, Quasha has made Eco Material a critical input supplier for low-carbon concrete at a moment when U.S. infrastructure decarbonization demand is accelerating.
Grant Quasha is Chairman and CEO of Eco Material Technologies, one of the largest suppliers of supplementary cementitious materials in North America.
The company produces, processes, and distributes fly ash and bottom ash for use in concrete and infrastructure projects, reducing the carbon intensity of cement. Quasha was named a 2025 EY Entrepreneur of the Year National Emerging Award finalist. Eco Material has scaled into a significant supplier to the U.S. construction industry as decarbonization requirements expand.
