Gypsum Board: Are Our Walls Leaching Toxins? | BuildingGreen

But Dick's research focuses on gypsum recovered from coal-fired electricity generating power plants. Gypsum that comes from coal plants is called flue-gas desulfurization gypsum, as it comes from the process that 'scrubs' sulfur out of the smoke stacks to reduce air pollution. "The gypsum that is recovered has good quality," says Dick.
