Any matter leftover after its primary use becomes a waste. Most of the ecological pollution faced by the world today is due to the massive production of waste. Landfills are the most commonly designed and monitored method of organized waste disposal that isolates waste from the surrounding environment. It consists of a liner system at the bottom to prevent the percolation of leachate to the underlying aquifers. For this the liner should have low permeability, preferably less than 10-7cm/s. Clayey soil is generally used as a liner. Where in clayey soil is not available alternative materials are used. In the particular study, main components of the liner are laterite soil, paper mill sludge and sepiolite. Paper mill sludge is a byproduct of paper industry whose disposal is difficult. Sepiolite is a fine grained mineral having good strength characteristics. The materials are mixed with soil in varying proportions and optimum mix required is determined. Parameters considered for the study are permeability, Atterberg limits, strength and compaction characteristics.
