Waste Utilization and Preservation of Resources
Developing country like India, the requirement of power or energy is satisfied through the coal-based power stations. From this thermal power station near about 180–185MT of ash generates and this huge amount of coal ash creates major problem for their disposal. Only 40–45% of that ash is able to dispose in proper way and the rest 60% are dumped randomly, this result in pollution of the environment and creates health hazards. Only 20–25% of that ash is disposed in construction of upstream ash dyke method and in construction of ash pond. The downstream construction method of ash dyke can be a good alternative for increasing the rate of disposal of ash. This method requires a good filter material because the filter media helps in protecting the fly ash material to carry away with the seepage. As we know the sand is good in filter material but here the alternative of this sand is found out i.e. ROBO sand (a waste product as it is manufactured from the waste stones). From investigation, it was found that the ROBO Sand has high permeability than river sand and less cohesion & high internal angle of friction. It also satisfies all the IS criteria for filter material. Then the results are analyzed by the PLAXIS 2D software based on Finite element analysis. The analysis is made in three different conditions. In this the factor of safety of dyke are found to be much higher than the required factor of safety (1.5).
