What is Gypsum?
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard/sidewalk chalk, and drywall.
Synthetic gypsum is created as a by-product of industrial processing. It is composed of calcium sulfate dihydrate, has the same characteristics as natural gypsum, and is a high-quality and environmentally friendly product.
What is gypsum used for?
Gypsum is used in a wide variety of applications: Gypsum board is primarily used as a finish for walls and ceilings, and is known in construction as drywall, wallboard, sheetrock or plasterboard. Gypsum blocks are used like concrete blocks in building construction.
How is gypsum made?
Gypsum is made up of oxygen, sulfur, calcium and water. As evaporation occurs the sulfur is not protected by the water and oxygen contacts sulfur bonding with it to form a sulfate (SO4 2). The sulfate then bonds with calcium (Ca) and water (H2O) to create gypsum.
What is Gypsum a by product of?
FGD gypsum is formed when fossil-fueled power plants utilize flue gas desulfurization systems to remove sulfur dioxide from gas pollutants. Using a process referred to as ‘scrubbing,’ gas pollutants are fed through calcium carbonate to eliminate impurities and environmental concerns. When the sulfur dioxide is removed, the gypsum by-product is formed.

Synthetic gypsum
The second most common use of CCPs is flue gas desulfurization (FGD) gypsum in wallboard. This material is produced by emissions control systems (scrubbers) that remove sulfur and oxides from power plant flue gas streams. Residues vary, but the most common uses in construction applications are FGD gypsum (or “synthetic” gypsum). This material is used in more than 40 percent of the gypsum panel products (wallboard) manufactured in the U.S. FGD gypsum can be used in cement production and geotechnical applications. It can also be used in self-leveling floor applications. The agricultural industry also uses this material to treat undesirable soil conditions and to improve crop performance.
- Raw material for wallboard
- Fill material for structural applications and embankments
- Feed stock in the production of cement
- Raw material in concrete products and grout
- Ingredient in waste stabilization and/or solidification
COMMON USES FOR SYNTHETIC GYPSUM
Synthetic gypsum is used interchangeably with natural gypsum in a number of applications. Examples of products that utilize synthetic gypsum include:
- Cement
- Drywall
- Glass Manufacturing
- Plaster
- Soil Amendments
BENEFITS TO USING SYNTHETIC GYPSUM
Manufacturing synthetic gypsum creates many positive economic and environmental benefits. Economically, manufacturing synthetic gypsum creates revenue from a product that otherwise incurred waste management costs. And by creating a valuable product from waste, material is kept out of landfills and environmental pollution is reduced. Furthermore, increased use of synthetic gypsum conserves natural gypsum and reduces the need to mine resources. Synthetic gypsum products even have benefits over natural gypsum products in terms of costs and environmental impacts.
GYPSUM IS ‘GREEN’
In addition to the infrequent occurrence of tinted green natural gypsum, all gypsum products (natural and synthetic) are also figuratively considered ‘green’ in terms of their recycling capabilities. This is due to the fact that gypsum is eternally recyclable, a major advantage when manufacturing gypsum into a commercial product. Gypsum is also a rare example of closed loop recycling, i.e. the ability to use product waste to make the same product over and over.
The cement industry in India is continuously growing. According to various research reports and in view of the upcoming massive infrastructure developments, the Indian cement consumption is expected to increase at a rate of 9-11 % per year. The rising costs of raw materials like gypsum (Fig. 1) and coal have been playing a heavy strain on the cement and construction industry. As result, Indian cement and plaster board companies have to explore alternate sources of gypsum and coal.
