Synthetic gypsum accounts for approximately 20 percent of U.S. raw gypsum use and is made from the byproducts of manufacturing and energy-generating processes, primarily from desulfurization of coal-power-plant exhaust gases. In excess of 80 percent of coal fly ash sold in the U.S. is used in gypsum board.
majority of gypsum consumed is used for agriculture, building plasters, the manufacture of portland cement, and wallboard products. The construction of wallboard manufacturing plants designed to use synthetic gypsum from coal flue gas desulfurization (FGD) units as feedstock has resulted in less mining of natural gypsum. The availability of

Synthetic gypsum is created as a by-product of industrial processing. It is composed of calcium sulfate dihydrate, has the same characteristics as natural gypsum, and is a high-quality and environmentally friendly product. 2. Synthetic Gypsum Comes in Many Forms. Synthetic gypsum is the name used to classify a variety of gypsum by-products.
J.M. Khatib, in Sustainability of Construction Materials (Second Edition), 2016 Chapter 25 concludes that, because of an increase in demand, gypsum mining will also increase. However, demand will force the construction industry to use more synthetic, waste and recycled gypsum.In Europe, it is anticipated that by 2035, 25% of recycled gypsum will be used.
Sep 13, 2021· Al-Shahba Cement and National Mining Corporation have signed a deal to build the 1Mt/yr plant in Cyrenaica region, according to the Libya Herald newspaper. The project is part of the ministry's plan to localise industry in the country, provide job opportunities for young people and drive development.
Other names include recaptured gypsum, byproduct gypsum, and synthetic gypsum. All of these terms refer to the same material produced by the forced oxidation process. The gypsum in both FGD gypsum and mined gypsum has the same basic chemical makeup— CaSO4«2H2O; however, the amount and types of trace materials and unreacted sorbents found in ...

Purity of gypsum is important to know, e.g. plasterboard typically requires a minimum of 70% gypsum. Synthetic/FGD Gypsum An alternative source of gypsum is synthetic gypsum derived as a side product from the flue gas desulfuriza tion (FGD) process – the socalled FGDgypsum. FGD plants are typically used at fossil
