Sparstane - Scrubber Waste to Fertilizer
True to the Dustex mission and vision of being in the forefront of innovative solutions, Dustex has acquired a unique technology. Sparstane is the solution for Flue Gas Desulfurization Gypsum (FGD Gypsum), a byproduct of coal-fired power plants. Sparstane converts FGD Gypsum into two high value materials - ammonium sulfate fertilizer and recycled calcium carbonate.
While there are many commercial uses for FGD Gypsum, such as wallboard and cement, the large volumes produced each year exceed the demand by over fifty percent. The wide gap between supply and demand forces the industry to store over half of the FGD Gypsum produced every year in expensive lined storage ponds and monitor them indefinitely. Dustex’s Sparstane technology eliminates this problem.
