Byproduct gypsum comes from a process used to remove sulfur dioxide from emissions at coal-fired power plants. After the power plant removes impurities from the coal combustion process, the remaining stack emissions are fed through a limestone slurry that removes sulfur dioxide.
Gypsum - Wikipedia
Gypsum may act as a source of sulfur for plant growth, and in the early 19th century, it was regarded as an almost miraculous fertilizer. American farmers were so anxious to acquire it that a lively smuggling trade with Nova Scotia evolved, resulting in the so-called "Plaster War" of 1820.
