What is gypsum?
 Gypsum, or calcium sulphate is a natural occurrence existing in large quantities all over the world. It is estimated that there are more than 2.500 billion tons in addition to the gypsum found as a natural ingredient in ocean water, approximately 1,6 kg per m3.
Two kinds of gypsum
Norgips is using both natural and industrial gypsum in their production of plasterboards. The industrial gypsum is a by-product from the cleaning of the flue gases from coal power stations, and by that, being a recirculated product. This converts polluted coal into clean energy and clean building materials.
 The industrial gypsum has a cleanness of close to 100%, and is much cleaner than most occurrences of natural gypsum.
In addition to these two types of gypsum, Norgips is also using all waste and cut-offs from its own production as raw materials in new plasterboards, so nothing is being wasted.
Norgips is recirculating all waste making it into raw materials in new plasterboards. Those of you who are especially "gypsum interested", may download a number of special articles about plasterboards, the environment and lightweight building technique.
