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.get price
