FGD's meaning in power plant has the advantage of logic and impact. First, it cleans up air pollution and reduces it by capturing 98% of the sulphur dioxide made when coal is burnt. This means better quality air for all. In addition, FGD systems have mature technology and a good reputation. They require only very low levels of maintenance and provide high availability. Thirdly, power plants can use FGD to meet tough environmental regulations and thereby escape penalties that might otherwise result in shutdowns. Furthermore, FGDs can help to minimize the health impacts of airborne pollution. They can benefit a whole community directly as well. Finally, gypsum--the material waste produces takes on a new life as building materials or other products. This not only does good for recycling but also generates some extra cash. On the whole, power plants investing in FGD technology is both practical and responsible.
