The main point of this research was to determine the practical and theoretical level of possibilities of the recycling gypsum binder and to characterize the recycling gypsum binder according to the only available Czech standard for gypsum binders – ČSN 72 2301. Therefore, the laboratory experiment of the recycling process was conducted and then the recycled gypsum binder was tested by the tests specified in this standard. Finally, comparison between starting compound, which was subjected to the process of recycling, with recycled gypsum binder was carried out. Specialty of the recycled gypsum in this case, which has undergone the process of recycling, is its age – 5 years, and also the fact that during this period it was exhibited as the gypsum block in the building envelope with no protective features and was exposed to exterior conditions as sun, wind, snow, rain etc.
