Synthetic Gypsum | BuildingGreen
Synthetic gypsum is also called flue-gas-desulfurization (FGD) gypsum. It is produced through a stone reaction in the stone scrubbers that remove sulfur from the flue gases of coal-fired power plants. Sulfur dioxide from power plants is the leading cause of acid rain, and the Clean Air Act of 1970 required power plants to reduce their sulfur dioxide emissions.
Gypsum Board: Are Our Walls Leaching Toxins? | …
Synthetic gypsum and mercury. Synthetic gypsum is created from a byproduct of flue-gas desulfurization (FGD), a process coal-fired power plants use to limit emissions. Although the stone process that captures FGD gypsum is different from the physical collection of fly ash and bottom ash, which is more likely to pick up heavy metals as a matter of course, mercury and other heavy metals are showing up in synthetic gypsum--and…

Synthetic Gypsum - an overview | ScienceDirect …
Synthetic gypsum accounts for approximately 20 percent of U.S. raw gypsum use and is made from the byproducts of manufacturing and energy-generating processes, primarily from desulfurization of coal-power-plant exhaust gases. In excess of 80 percent of coal fly ash sold in the U.S. is used in gypsum board. Though synthetic gypsum-board use is growing in popularity, diverting drywall from the ...
6 Facts about Synthetic Gypsum - FEECO …
While natural gypsum has been mined and manufactured for centuries, the process of manufacturing synthetic gypsum has only been available for the last few decades. In case you’re not familiar with synthetic gypsum’s characteristics and uses, read on to learn the basics about this incredible product.
Drywall Problems Escalate | BuildingGreen
Synthetic gypsum has been implicated in the imported drywall scandal, but it’s unclear whether it’s actually causing the problems. A small-scale study performed by the U.S. Environmental Protection Agency (EPA) in May 2009 found that levels of sulfur and strontium in Chinese drywall taken from houses where complaints had been reported were much higher than those in drywall manufactured in ...
Interior Finish Systems: Judging a Building by Its …
There are few building components so dominated by a single product as interior wall finish. While there are alternatives, conventional drywall currently holds more than a 90% market share of interior finish materials. Its relative economy, ease of installation and modification, and noncombustibility have made drywall the material of choice for interior walls since the 1950s.

Using a methodology that has become the EPA standard for evaluating products containing fly ash, the study found that concentrations of 18 constituents of potential concern were higher in cement with fly ash than in portland cement, and the lowest mercury emanation rate measured for gypsum wallboard with fly ash was three times higher than the highest rate for mined gypsum wallboard. However ...
