TECHNICAL REPORT 1994 - UNT Digital Library

FGD-gypsum have been proposed and, in many cases, demonstrated. Stabilized FGD material can be used as a liner for a landfill. Some FGD materials are processed to a fixed stabilisate and disposed in abandoned surface coal mines. An alternate approach to utilize both high and low quality FGD-gypsum is to produce ammonium sulfate fertilizer.
