This study was focused on the historical evolution of the waste management policy carried out by the Spanish industry devoted to titanium dioxide pigments manufacturing for minimising its environmental impact. This challenge was achieved by modifying the original chemical process and converting the originally dissolved sulphate 2. Gypsum Helps Reclaim Sodic Soils. Gypsum is used in the reclamation of sodic soils (Aldrich and Schoonover 1951). Where the exchangeable sodium percentage (ESP) of sodic soils is too high, it must be decreased for soil improvement and better crop growth. The most economical way is to add gypsum which supplies calcium.36 Reasons for Using Gypsum Holloway Agriculture

The granular or powdered form of gypsum specifically marketed towards garden use has a variety of different applications. Primarily, gypsum is used for helping to break up heavily compacted clay soils making them more porous and able to absorb moisture. This is particularly helpful in areas prone to drought.

Gypsum uses include: manufacture of wallboard, cement, plaster of Paris, soil conditioning, a hardening retarder in portland cement. Varieties of gypsum known as "satin spar" and "alabaster" are used for a variety of ornamental purposes; however, their low hardness limits their durability. Gypsum wallboard and plaster: Wallboard andGypsum is widely used in the construction sector, and its worldwide consumption has been increasing for several decades. Depending on the lifetime of the used gypsum products, an increase of gypsum in construction and demolition waste follows.

Gypsum is a soft mineral composed of calcium sulphate dihydrate ( CaSO4 ⋅ 2H2O C a S O 4 ⋅ 2 H 2 O ). It is commonly found in sedimentary rock formations distributed all over the world. It is a white or greyish material and is water soluble. Hence it can easily be used to produce plaster and drywall where it is mixed in water to form a paste.Meaning of Gypsum. Gypsum is a soft sulphate mineral which is composed of calcium sulphate dehydrate and Its chemical formula is CaSo42H2O. Also Read: Plastering Purpose, Requirement & Technical terms. Uses of Gypsum.
