Flue Gas Desulfurization Gypsum (FGD gypsum, synthetic gypsum, pre-consumer recycled gypsum)

Pre-consumer recycled content (synthetic gypsum) is created from environmental control systems installed in the smokestacks of coal-fired power plants. These systems capture particles from coal burning as they travel through the smokestack or flue. This becomes Flue-Gas Desulfurization (FGD) gypsum. FGD in drywall results in the global distribution of mercury, a potent developmental and neurotoxic metal that persists in the environment, accumulates in the food chain, and is highly toxic. The very pollution that is being captured in the flue of the power plant is being released from the smokestacks of wallboard factories that use FGD residuals. https://healthymaterialslab.org/tool-guides/hml-resources
