The Benefits of Recycling and Reusing Fly Ash Waste

2014-9-23  The United States EPA recently determined that coal ash from power plants is safe for use in cement production. 4 Making cement is an incredibly energy-intensive process; concrete production contributes 5 to 8 percentof all the greenhouse gases produced in the world. However, concrete made with fly ash can reduce carbon emissions by as much as 90 percent, while also developing a more

Value in Waste: Fly Ash Reuse and Recovery Opportunities

In many cases, fly ash is coming from a storage pond and requires drying before it is ready for reuse or recovery applications. Unfortunately, fly ash drying is made challenging as a result of the dusty nature of fly ash. As such, dust suppression via agglomeration is often employed prior to drying.

Advanced technology recycles coal ash for use in concrete

2020-10-8  Recycling coal ash for concrete is practical and safe, but excess carbon in the ash must be removed before it’s suitable for reuse. In most cases, coal ash is between 6% and 15% carbon, which is too high to meet specifications for concrete. The STAR unit reduces the carbon level below 1%.

CiteSeerX — RECYCLING OF COAL FLY ASH BY CERAMIC

CiteSeerX Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Coal fly ash was used as raw material for the preparation of ceramic materials by a conventional powder technology route. Powder compacts were made from as-received fly ash, from calcined fly ash and from powder mixtures having 90 % of calcined fly ash plus a low-cost mineral as additive (dolomite, CaCO3.MgCO3).

Value in Waste: Fly Ash Reuse and Recovery Opportunities

One new study has taken alumina recovery research a step forward with some promising results; by combining a CaCl2 calcination step with H2SO4 leaching, researchers were able to obtain greater than a 95% recovery of alumina from the fly ash. In comparison, the study found direct acid leaching could only recover about 2 4.75% alumina.
