Supplying future needs

Fly ash is not going away

Coal-generated power currently makes up 40% of the U.S. energy mix.2 And while the total share of coal-generated power continues to decline, the amount of coal-generated power remains steady.3

Supply will remain steady between continued production and reclamation efforts:

  • Despite coal plant retirements, coal usage is expected to grow 3.4 percent over the next two decades.4
  • Fly ash production is expected to increase 2.6 percent through 2033.5
  • Technologies to improve ash quality will increase the volume of ash available for beneficial use.
  • Reclaiming fly ash from disposal facilities will increase supply significantly.

Fly Ash Production Forecast
53+ million tons annually6

This means that fly ash will continue to be produced
and continue to be available for beneficial uses
in the marketplace.

Improving our national infrastructure

Using fly ash improves products in many ways:

Fly ash concrete is stronger, more resilient, and lasts longer than concrete made with only portland cement.7

Fly ash is an essential component for large-scale concrete pours.

Fly ash is used in a variety of concrete mixtures:

  • Residential construction
  • Roads, bridges and tunnels
  • Dams and reservoirs
  • Skyscrapers
  • Pavements and floors
Fly ash creates a less permeable, longer lasting
concrete—resulting in infrastructure cost savings.

Helping the environment

Fly ash use in concrete reduces greenhouse gas emissions equivalent to removing 2.5 million cars from the road every year.8

Strengthening our economy

More than half of all the concrete produced in the U.S. is made with fly ash.

"The cost to build roads, runways and bridges would increase by an estimated $104.6 billion over the next 20 years if fly ash were not available."

Builders Association9

"Economic benefits can include job creation in the beneficial use industry, reduced costs associated with CCR disposal, increased revenue from the sale of CCRs and savings from using CCRs in place of other more costly materials."
— EPA’s Beneficial Use Risk Evaluation10

Building a more sustainable future

  • The beneficial use of fly ash in concrete supports sustainable construction.

  • EPA’s detailed study affirmed the safety in using fly ash concrete.10

  • Many of the world's innovative and sustainable buildings have been made possible through the use of fly ash concrete. Using fly ash qualifies buildings for LEED and Green Globes green building certification credits.11

With strong contributions to our economy, infrastructure, and a more sustainable future,
fly ash will remain an accessible raw material for U.S. industries and continue to attract new investments.
