• FGD Gypsum Market

     · FGD gypsum, also known as synthetic gypsum, is manufactured through the process of flue gas desulfurization. Flue gas desulfurization is a technology used to eliminate sulfur dioxide (SO2) from exhaust flue gases of fossilfuel power plants. The process keeps the air clean and provides sustainable and ecologically sound source of pure gypsum.
