The utilization of sepiolite in landfill liners

Abstract:
In this study, sepiolite and natural soil-added sepiolite mixtures were studied to find out whether they can be used as compacted landfill liner, as they are an economic alternative to the other compacted day liners or not. Geotechnical and physico-chemical properties of sepiolite and sepiolite mixtures, containing 25% and 50% natural soil by weight, and compacted at water contents ranging from 35% to 60%, were determined by hydraulic conductivity, leachate analysis, unconfined compression strength, consolidation, volumetric shrinkage and swelling tests. The test results showed that the compacted natural soil-added sepiolite mixtures exhibit lower permeability and swelling properties, and higher compressive strength than pure sepiolite. The overall evaluation of the results has revealed that the natural soil-added sepiolite showed good promise and it can be used as a landfill barrier due to its high capacity of contaminant adsorption.
