The value of FGD gypsum to gypsum users depends on the chemical and physical properties and delivery cost compared to supplies of natural gypsum. The ability of the wallboard facility to accept FGD gypsum without the need for significant plant modifications will also influence the price they will be prepared to offer.
The byproduct from these systems is gypsum (CaSO4∙2H2O), which a number of plants sell to wallboard or cement manufacturers. In other cases, the material may be land-filled.
