· Lafarge is an industry leader in the use of synthetic gypsum. With the addition of the Buchanan plant, nearly all of the gypsum board manufactured by Lafarge in North America will be made with 100 percent recycled paper and recycled gypsum. Currently, Lafarge's Silver Grove, Kentucky plant and Palatka, Florida plant qualify for this distinction.
Using "synthetic" or recycled gypsum board can significantly reduce several of these impacts. 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.

The construction of wallboard manufacturing plants designed to use synthetic gypsum from coal flue gas desulfurization (FGD) units as feedstock has resulted in less mining of natural gypsum. The availability of
Gypsum plants use synthetic gypsum for the primary raw material. When combined with the recycled paper, this yields a total recycled content of up to 99% for ProRoc® gypsum board. Some of our plants have implemented construction waste management programs that incorporate post-consumer gypsum board back into the production process.
· 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. I googled synthetic gypsum board and came up with one processor. FEECO International.
· Synthetic gypsum is an industrial by-product, containing over 10% of free water. Therefore we've improved processes according to our experiences: by pre-dry dihydrate gypsum first, then calcining using boiling furnace, we can …
