Byproduct Gypsum : Byproduct gypsum is the ultimate recyclable. It comes from a process used to remove sulfur dioxide from emissions at coal-fired power plants. After the power plant removes fly ash and other impurities from the coal combustion process, the remaining stack emissions are fed through a limestone slurry which removes sulfur dioxide.

If coal were pure carbon, then the only thing we would have to worry about at coal-fired power plants is the carbon dioxide formed when coal burns. Unfortunately, coal often contains other chemicals. Sulfur is one common element found in coal. When burned, the sulfur in coal turns into sulfur dioxide.

The basic function of the power plant is to convert energy in coal to electricity. Therefore, the first thing we should know is how much energy there is in coal. Energy content of coal is given in terms of KiloJoules (kJ) per Kilogram (kg) of coal as the Gross calorific value (GCV) or the Higher Heating value (HHV) of coal. This value can vary .
