Gypsum board manufacturers rely increasingly on flue-gas desulfurization (FGD) gypsum or synthetic gypsum as an effective alternative to natural gypsum. In fact, FGD gypsum was first integrated into the core of gypsum board almost a quarter of a century ago
Synthetic gypsum, derived primarily from environmental con-trols on coal-fired power plants by a process known as flue gas desulfurization (FGD), has become a significant raw material resource used in the manufacture of gypsum wallboard products. Demand for synthetic gypsum has steadily grown since the 1980s, and in 2003 about 26% of the total gypsum used for manufacturing wallboard in the ...
Synthetic gypsum, which comprises about 95%, by weight, of American Gypsum wallboard, is processed almost identically as you would natural gypsum rock: Dry and calcine Synthetic Gypsum into a stucco before mixing it with water and other setting and binding ingredients in a continuous mixer

Synthetic content varies from product to product, and also from manufacturing plant to manufacturing plant. While about half of gypsum today is synthetic gypsum (and that number is rising) as plants are built next to power plants instead of gypsum mines, I'm sure if you look around it wont take long to find a plant close to you that offers natural mined gypsum instead of synthetic gypsum.
This paper describes a South African process for manufacturing gypsum by reacting limestone with sulfuric acid as an alternative to relying on low-grade natural gypsum deposits.
111 1 KUUUL 11UI1 United States Gypsum Company (USGC) has developed specifications and guidelines covering the chemical and physical aspects of synthetic gypsum to help predict end use acceptability in wallboard manufacture. These guidelines are based in part on past experiences with natural ad synthetic gypsum. Similarly, most wallboard manufacturers in North America have …
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 ...
Synthetic gypsum generated by various industrial processes, including FGD of smokestack emissions, is very important as a substitute for mined gypsum in wallboard manufacturing, cement production, and agricultural applications (in descending tonnage order).
What is Gypsum?By using synthetic gypsum in its manufacturing process, the gypsum industry contributes to a cleaner environment in at leas
The Gypsum Wallboard Manufacturing Plant uses synthetic gypsum (also referred to as desulphogypsum or DSG) produced by the flue gas desulphurization systems in NB Power Generating Stations, in the production of the wallboard products.
Introduction to FGD Gypsum FGD Gypsum is a unique synthetic product derived from flue gas desulfurization (FGD) systems at electric power plants. Sulfur dioxide emission control systems used by coal-fired power plants remove sulfur from combustion gases using "scrubbers."
FGD Gypsum is an important supplement to the supply of natural Gypsum. This synthetic This synthetic Gypsum has a higher purity (Gypsum content of 96%) than most natural Gypsum (80%).
> CertainTeed Gypsum is committed to resource conservation: – The face and back paper used for our gypsum board consists of recycled paper. – Synthetic gypsum, specifically flue-gas desulfurized gypsum, is used at plants where
Manufacturing. American Gypsum believes in the power of conservation efforts throughout the manufacturing process. We comply with of government standards when it comes to airborne emissions by burning natural gas and participating in fuel efficiency programs.

Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 ·2H 2 O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard chalk and wallboard.
Wallboard Recycling Services for Manufacturers. USA Gypsum provides wallboard recycling services for manufacturers' production scraps by removing the product to other markets or processing and returning the gypsum, free of facing and residuals, for use in new board manufacturing.
In fact, the U.S. gypsum industry has diverted almost 8 million tons a year of FGD gypsum to board manufacturing using material that otherwise would have been sent to local landfills. It is important to point out that both natural and synthetic gypsum used in gypsum boards are considered to be nontoxic and safe and are often mixed together at a manufacturing plant.
Synthetic gypsum is used in the manufacturing of drywall, drywall compounds, cement, concrete and concrete products. 1.3. Name, Address, and Telephone of the Responsible Party
