-Coal account for more than half of the electricity produced in the world.
-These power plants produce byproducts like fly ash which is captured from the exhaust of the boiler and bottom ash which is heavier and falls to the bottom of the boiler.
-These by-products were originally treated as waste and disposed off in landfills.
-In recent years, Coal fly ash (CFA) has been developed to be a recyclable raw material for producing cement, concrete, wallboard, mortars, stuccos, blocks, bricks, shingles, paints, etc.
-Due to the environmental awareness and commitment to incorporate recyclable materials into these products, CFA will become an increasingly important raw material in the years to come.
