SUSTAINABILITY 20 Gypsum - the raw material Rigips Austria is aware of the great responsibility the construction industry has towards the environment. During the entire production process and in the product lifecycle, measures are taken specifically to minimise the effects on the environment. Gypsum has been used as a building material for more than 5,000 years. The natural stone occurring as a raw material is recyclable to 100% and for infinitely many times, and it is harmless to the skin as well as fire-resistant. The production process (see Figure 15) is completely reversible: through dehydration, water is extracted from the rough stone and gypsum powder is created. When water is added to the gypsum powder, you will receive gypsum again.
