GYPSUM - EDA

Gypsum products can be counted amongst the very few construction materials where “closed-loop” recycling is possible, i.e. where the waste is used to make the same product again.. Gypsum as such is 100% and eternally recyclable. You can always reuse Gypsum because the chemical composition of the raw material in plasterboards and blocks always remains the same.

Gypsum Ore – FMC

Gypsum is an evaporate mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO4.2H2O) is very similar to Anhydrite (CaSO4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.
