The term "synthetic gypsum" has been used widely to encompass materials produced by a variety of industrial processes. In addition to FGD gypsum, synthetic gypsum includes materials such as phosphogypsum, (a byproduct of processing phosphate ore to make phosphoric acid), Titanogypsum (a byproduct from the production of titanium dioxide), fluorogypsum (a byproduct from the production of

Phosphogypsum refers to the calcium sulfate hydrate formed as a by-product of the production of fertilizer from phosphate rock.It is mainly composed of gypsum (CaSO 4 ·2H 2 O). Although gypsum is a widely used material in the construction industry, phosphogypsum is usually not used, but is stored indefinitely because of its weak radioactivity.

By-product, or synthetic, gypsum is viewed as environmentally-friendly because it incorporates sulphur removed during flue gas desulfurization (FGD) at coal-fired power plants and other industrial sites. If the sulphur were not captured and used to produce by-product gypsum, it may end up as acid rain. Power plant operators should therefore adjust their processes to create saleable, pure FGD
