How much recycled material is used in ToughRock® gypsum board?
There are two major components of gypsum board – the paper skins and the board core. The recycled content question applies to both of these components. The paper is produced using 100% recycled fiber. The recycled content of the core varies from plant to plant. Sources of recycled gypsum are plant waste, new home construction site cutouts, chemical gypsum, and Flue Gas Desulfurization (FGD) gypsum. Georgia-Pacific Gypsum enforces very stringent quality control standards at all of its plants. Rejected board is crushed, paper is separated, and gypsum is put back into the process. This process, conducted at all Georgia-Pacific Gypsum plants, means the board could contain as much as 8 to 10% recycled gypsum. By-product gypsum from some chemical processes is also used in the board core. Our Wheatfield, Indiana plant uses 100% FGD gypsum produced by the Northern Indiana Public Service Company (NIPSCO).
