    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.Онлайн-запрос
