FGD has numerous advantages and can be easily seen. First of all, it drastically reduces SO2 emissions meaning that the environment will be spared from acid rain which has such fatal effects on ecosystems and architectural works in the long-term. Second, this resolves liability issues and at the same time protects a companies image with authorities by indicating its commitment to environmental management. Thirdly, the health and safety of local people are improved by FGD systems lowering the level airborne pollutants associated with such medical problems as bronchitis. Finally these systems offer a way to produce gypsum, by a little bit of extra cost but still a profit. Building on FGD infrastructure isn't only an environmental duty; it also pays off as a long-term investment.
