  • Patent number: 9464002
    Abstract: Compositions and methods for producing a manufactured product, a method for making a liquid absorbent, and processes for disposal of flammable liquids with a flue gas desulfurization by-product. The compositions for the manufactured products combine a binder and the by-product. The composition contains a greater percentage by weight of the by-product than the binder. The methods for producing manufactured products include dewatering the gypsum-depleted waste stream to reduce a water content, and forming the manufactured product. The method for making a liquid absorbent includes dewatering, granulating, drying, heating, and packaging a granulated gypsum-depleted composition as the liquid absorbent. The processes for disposal of flammable liquids include distributing a by-product into contact with flammable liquid, absorbing the liquid, transporting, and igniting the flammable liquid. The artificial soils are a combination of by-product and animal waste, human waste, or another bio-solid.
