CertainTeed is committed to resource conservation:

The face and back paper used for our gypsum board consists of 100% recycled paper.
Synthetic or “by-product” or DSG gypsum produced from the desulphurization of flue gases at coal-fired power plants is used where sources
are available. Currently three manufacturing plants—Carrollton, Kentucky, Moundsville, West Virginia and Toronto, Ontario—use 100%
synthetic gypsum.
The total recycled content for these synthetic gypsum plants is 96%.
In-plant scrap is recycled back into the process.; Our 14 gypsum board manufacturing locations provide regional
material coverage throughout North America.
Although LEED rating systems do not currently address emissions for all building materials and their effects on indoor air quality, finished
CertainTeed gypsum board products have no reportable VOCs and will not affect indoor air quality.
