Calculation of leachate generated from municipal solid waste landfill using modeling method

Abstract

Calculating the volume of leachate generated in solid waste landfilling activities is a very meaningful data for environmental protection in general, because leachate is the main polluting factor arising from these activities. If the leachate generated is not controlled, the risk of this factor from the landfill is clear and direct to the surface water, underground water and soil environment. Previously, forecasting the volume of leachate generated or calculating leachate was mainly based on landfill area and rainfall. The water balance method is a basic method but does not calculate all the effects of the landfill process on the volume of leachate generated. Some other methods have bulky and complicated calculations. This study was conducted to propose a method to calculate the amount of leachate generated when operating a landfill more accurately under Vietnam's operating conditions. The calculation model built on the Matlab platform is simple and easy to apply when calculating for any municipal solid waste landfill.
