Power Industry has been, and continues to be, a key factor in the economic growth of most of the developed and developing countries. In general, the power sector represents the industries with highest environmental impact and has constantly been subject of increasing pressure from new economic, energy saving and environmental issues. Coal based Power Generation has been the backbone of the any developing country. Indian coal is of low grade, having ash content as high as 45% in comparison to imported coals which have low ash content of the order of 10-15% (CEA, 2014-15). Thus, a large amount of ash is being generated by the coal based thermal power plants in India, which not only requires huge areas of precious land for its disposal and management, but, is also one of the major sources of pollution of air, water and soil. This article attempts to underline the uses of this industrial solid waste to make an efficient tool for management of fly ash. To save our environment more research and development needed to discuss the above stated issues.
Suitability of leaching test methods for fly ash and slag a reviewManoj Kumar Tiwari
Fly ash and slag leachate pollution can be of great environmental concern due to generation
of these wastes in huge quantities from their respective industrial units, mainly coalbased
thermal power plants and iron and steel plants. For simulation of natural leaching in
laboratory, various leaching methods are available, but selection of a method that can
exactly simulate the real-life scenario for accurate estimation of various pollutants is
challenging; particularly, the heavy metals present and impact due to reuse or disposal of
these wastes. For choosing the most suitable leaching method according to specific situation,
one must primarily consider the chemical and physical properties of wastes, the
composition of the source, age of waste disposal, and the climatic conditions of the
disposal area. Since these factors may not be specified, a variety of leaching methods with
relevant equipment have been proposed by researchers; that are based on their required
information to particular conditions in absence of a prescribed protocol and non standardization
of equipment. The present review is an attempt to investigate the suitable
leaching method for coal fly ash and slag.
