Modification of residual soil with palm oil fuel ash as potential landfill liner

In Malaysia, wastes that being disposed of to landfill sites have increased tremendously. This leads to another environmental problem where the leachate penetrates through the landfill barrier system and contaminates the groundwater source. In this study, palm oil fuel ash (POFA) is employed to modi...
