The economical use of calcium sulphate dihydrate - which is a power station product in the flue gas desulphurisation by the lime/wet-washing process, and requires disposal - in the form of broken briquettes can be substantially expanded, if the storage stability, abrasion resistance and strength of the material is improved by admixing, according to the invention, a binder - preferably consisting of gypsum from flue gas desulphurisation plants, which has a binding capacity - to the gypsum before briquetting.
