Beneficial uses of fly ash will be continuously analyzed

Burns & McDonnell says beneficial use of CCR materials can provide economic and environmental benefits, as such uses can reduce costs associated with developing and operating disposal facilities, provide a potential revenue source through the sales of these materials, and reduce the demand for native raw materials through substitution of CCR materials.  The firm has experience studying or implementing beneficial use of CCR in the following areas:

• Underground and surface mine reclamation

• Coal yard base and pond liner material (roller compacted concrete)

• Leachate collection system media

• Protective soil cover systems

• General fill material

• Soil stabilization

• Portland cement concrete

• Railroad sub-ballast

The Mcilvaine company will be continuing to analyze the potential volume and price for each of these end uses. It will also be looking at other products such as bricks which are being manufactured in the Longking dry scrubber process.

Another question would be the value of very pure fly ash without any metal which would result after REE recovery.
