How to Recycle Fly Ash

Fly ash is a byproduct of coal-fired power plants. Instead of disposing this waste and overloading local landfills, people are finding ways to recycle it, which helps preserve the environment.

Instructions

    • 1

      Mix fly ash with hot asphalt for paving. This mix containing fly ash has similar properties to that containing stone dust or hydrated lime. The fly ash must be dry before mixing it with the asphalt. You also can make bricks containing fly ash.

    • 2

      Mix fly ash with solid hydrocarbon fuel and gas that contains oxygen to reduce the erosion of the operating components in a reactor. Repeating the process of introducing this mixture helps to keep a predetermined range of temperature within the combustion zone.

    • 3

      Employ fly ash during the winter as a means to keep them free of ice and snow.

    • 4

      Create a mixture of fly ash and concrete. Recycling fly ash in this manner will reduce the need to mine for clay. It also will reduce carbon emissions during the creation of Portland cement.
