Marketing Of Byproduct Gypsum From Flue Gas Desulfurization

Competition in the wall- board plant market would be more localized and, in some cases, less severe because of the large gypsum requirements of wallboard plants and the tendency in some cases for wallboard plants to be clustered at sources of gypsum, creating very large localized gypsum requirements. FGD gypsum marketing differs from the marketing of other FGD byproducts such as
