Benefits

Industry

• Power stations
  • Minimize landfill and ash pond disposal costs
  • Reclaim and reuse existing landfill and ash pond capacity
  • Recycle activated carbon used for mercury capture
  • Recover residual carbon for use as fuel
• CCP suppliers
  • Increase sales by converting poor-quality fly ash into high-quality pozzolan and by recovering multiple valuable components from the fly ash
• Cement producers
  • Broaden fly ash source base
  • Improve process control by reducing fly ash chemical variability
  • Produce inexpensive low-carbon aluminum source for clinker
  • Save energy by processing and sintering less limestone
  • Recover residual carbon for use as fuel
  • Produce blended/fly ash cement
  • Produce high-quality pozzolan for sale in the open market
  • Generate CO2 credits (a ton of utilized fly ash saves about a ton of CO2)
• Ready mix and concrete producers
  • Use low-LOI fly ash as a Portland cement substitute
  • By adding low-LOI fly ash to concrete, produce a superior quality product
    • Improve concrete durability and strength, freeze-thaw resistance, workability, finishing and pumping qualities
    • Reduce concrete permeability, drying shrinkage, heat of hydration, alkali-silica reactivity, bleeding and segregation
  • Generate CO2 credits

Community and Society
