Managing Synthetic Gypsum How Duke Energy Manages Synthetic Gypsum and FGD Solids
Gypsum is the main ingredient used in the manufacture of drywall. Duke Energy sells much of the synthetic gypsum produced at our generating facilities to drywall manufacturers. We also supply synthetic gypsum for use in agricultural applications and for use in manufacturing portland cement. The gypsum that Duke Energy produces that is not used in drywall manufacture, cement manufacture or agriculture is placed in on-site landfills that are permitted by the state where the landfill is located. All of the flue gas desulfurization (FGD) solids produced by Duke Energy are placed in on-site or off-site landfills that are permitted by the state where the landfill is located.
