Gypsum Plasterboard and the environment

Gypsum (CaSO 4.2H 2 O) is the hydrated form of Calcium Sulphate (CaSO 4). Calcium Sulphate is a by-product of the evaporation of lake and seawater and occurs in beds up to several metres thick. Calcium Sulphate Dihydrate (Gypsum) is commonly hydrated by groundwater. The UK is largely self-sufficient in gypsum.
