At present main source of energy in India are thermal power plants that run on coal for energy production. An estimated total fly-ash produced as by-product from these electric plants yearly accounts to 100 million tons. Fly ash utilisation has picked up by cement factories and others but still percentage is unsatisfactory. This fly-ash is pumped into the ash pond which with time escapes into the environment at the bottom level or from surface. Thus the hazardous waste is a critical challenge to the environment and water bodies, therefore, must be managed at the earliest. Recent GCL or HDPE bottom lining layers are a suggestive solution for preventing toxic materials from seepage into the surrounding areas.
