For power plant operators, the advantages of FGD are obvious and practical. First, thanks to removing SO2, by FGD plant operators are able to meet environmental legislation and avoid fines. Second, FGD systems reduce air pollution, contributing to a healthier society as well as lower incidences of respiratory disease. Thirdly, a company's credibility is increased with this technology by making sure it shows that they are committed to sustainable development. Finally, with FGD stand-alone shortcut plants can also improve the operational efficiency of a power plant system. For instance, gypsum--a byproduct that albeit carries considerable environmental risks when left alone on its own--can be turned into dry wall and other products. The gypsum obtained through this process can be sold to various industries as raw material, offering a new source of revenue for power plant bridges.
