Construction and demolition activities in King County (outside Seattle) generate an estimated 31,000 tons of gypsum wallboard waste per year. Only about 6,000 tons of this supply are currently recycled.1 It is estimated that 12 percent of gypsum wallboard becomes scrap during installation.2 Most of this material waste is generated from new construction, followed by demolition, manufacturing and renovation.
Gypsum can be a naturally occurring mineral or synthetic—a byproduct of flue gas desulfurization used by power-generating plants to remove polluting gases from their smokestacks. Recycled gypsum can be used in new wallboard, as an additive in concrete and as a soil amendment.
