Nearly 90% of the the coal-based thermal power plants, which burns pulverized coal to produce fly ash. Presently, about 112 million tonnes of fly ash is generated annually. Such a huge quantity of fly ash poses a challenging problem in its disposal. Conventional methods of disposal viz., dry and wet disposal schemes creates problems like land usage, health hazards and environmental pollutions (air is polluted due to dry dumping, surface water is polluted due to surface runoff, ground water is polluted due to infiltration and soil is polluted due to leaching). Fly ash, being treated as a waste, but in fact it is a resource material, as it is now being used in cement making, brick making, backfilling, embankment, agriculture etc. Thus, it is the action of human being that determines the worth of any material. Further, potential for gainful utilization remains in the category of waste, till its potential is understood and to put in right use by the scientific community. Fly ash is one such example, which has been treated as a waste material, in India, till the last decades of the 20th century and has now emerged not only as a resource material but also as an environment savior. This paper, thus, characterizes the physico-chemical properties of fly ash and utilization of fly ash as an adsorbent for the removal of dye/color from the wastewater
