Flue Gas Desulfurization Gypsum acaa-usa

The second most common use of CCPs is flue gas desulfurization (FGD) gypsum in wallboard. This material is produced by emissions control systems (scrubbers) that remove sulfur and oxides from power plant flue gas streams. Residues vary, but the most common uses in construction applications are FGD gypsum (or "synthetic" gypsum).

The wallboard plant market consisted of the 52 wallboard plants projected to be in operation in 1985. The geographic distribution of the plants is almost entirely related to sources of gypsum, either mines or import points, as shown in Figure 2. The total wallboard plant gypsum requirements were projected to be 10.4 million ton/yr.

Frequent Questions about the Beneficial Use of Coal Ash

May 26, 2020 Wallboard plants are sited in close proximity to power plants for access to raw material, with a considerable investment involved. Thus, FGD gypsum used for wallboard manufacture is a product rather than a waste or discarded material. This use and similar uses of CCR that meet product specifications would not be regulated under the final rule."
