Abstract Flue gas desulfurization (FGD) gypsum is a waste material produced in desulfurization of flue gases in power stations and heating plants in high amounts. However, the industrial use of FGD gypsum is insufficient considering the amount of its production. Nowadays, it is mostly used for the production of gypsum plasterboards only, and the rest is deposited at waste disposal sites.
