Sanitary landfilling is a low cost and well established waste disposal technique applied worldwide. However, it generates heavily polluted leachate. India being a tropical country receives heavy rainfall from south west monsoons and north east monsoons, promote water percolation into the landfill which aggravate the problems due to leachate percolation. So there arise an imminent necessity to devise a methodology which is highly efficient and economical to curb this menus. The study deal with the aspect of using Bentonite Halloysite mixture as a potential material for using as a landfill liner keeping in absorbing properties of halloysite nanoclay towards heavy metals and ammonia ions. The optimum needle density of the Geosynthetic clay liner and the mass density per square centimeter of the bentonite fill inside the GCL is determined. The impact of the Halloysite nanoclay in the bentonite composition used in the GCL on the atterberg limits and free swell index of the GCL filling is also evaluated to compare with the effect of montmorillionite nanoclay mixed with bentonite in GCL.
