FGD gypsum is a by-product of the desulphurisation of gases produced when coal is burned to produce power. It is mainly used for internal construction products, such as plaster, plasterboards and wall panels. Evonik Power Minerals markets FGD gypsum as steagips^®.

What is FGD gypsum?

FGD gypsum is produced from the desulphurisation of flue gases from coal-fired power stations. It is used as a substitute for natural gypsum and can also be used as a setting controller in cement production or as a filler material in the production of varnishes, adhesives and plastics.

We produce FGD gypsum under the brand name steagips®. steagips® allows high-grade utilisation of FGD gypsum in the construction industry, helping reduce consumption of natural resources and preserving natural landscapes.

The technological properties of FGD gypsum are the same as those of natural gypsum. FGD gypsum normally has a slightly higher calcium sulphate dihydrate content and a more uniform particle distribution than natural gypsum.

steagips®  is suitable for the following applications:
