Abstract

The objectives of this study are to Determine the settlement and leachate generation from landfill lysimeters of municipal solid waste. Two lysimeters with a diameter and height of 0.70 m and 2.40 m, respectively, were prepared. The lysimeters were operated with and without leachate recirculation. The settlement and leachate generation were quantified every day. The analisys of settlement were used with the hyperbolic fungtion and curve fitting. Based on the experiments it is known that garbage pile settlement in lysimeter conducted leachate recirculation (L-2) shown a greater settlement than lysismeter without recirculation (L-1) either the hiperbolic function and curve fitting. The ultimate settlement (Sult), for L-1 and L-2 use the hiperbolic function determined as 0.487 m, and 0.53 m, respectively. Meanwhile Sult determined use the curve fitting 0,487 m, and 0,53 m for L-1 and L-2 respectively. The lysimeter conducted with recirculation of leachate shew the quantity of leachate generated larger than the lysimeter without recirculation
