Until recently, there were no regulations on contaminants in drywall. Even now, limits exist for only one contaminant, sulfur, yet biocides and other chemicals added to drywall may also raise health concerns.

Production and resource utilization of flue gas desulfurized gypsum
111· At present, due to the high decomposition temperature and complex composition of gypsum, only a small part of FGD gypsum is recycled; most of it is directly stored as solid waste. This not only causes serious pollution to the environment, but also wastes calcium and sulfur resources.Gypsum Nature's Way Resources,The primary environmental impacts of raw gypsum are habitat disruption from mining, energy use, associated emissions in processing and shipment to solid waste from disposal.
