Building solutions for the gypsum manufacturing sector - Construction & Construction Materials

The chemical composition of gypsum is calcium sulfate dihydrate (CaSO4·2H2O). There are two types of gypsum: natural gypsum and Flue-Gas Desulfurization (FGD) gypsum. FGD gypsum is a by-product of desulfurization of flue gas from the stacks of fossil-fueled power plants, and the emissions captured from smoke stacks are purified into a hard substance and manufactured into gypsum. FGD gypsum has been used to manufacture gypsum board for more than 30 years.
