  • What is Gypsum – eurogypsum

    Gypsum can be milled mixed with water and then resume its original rock-like state. This means it can be shaped and hardened. Gypsum also has a “closed recycling loop”, meaning it can be endlessly recycled while maintaining a high quality. One alternative to natural gypsum is Flue Gas Desulphurisation Gypsum, or FGD Gypsum.
