Abstract

The objective of this study is to find solid waste decomposition in landfill without leachate discharge. This study was observed variation of landfill gas production rate and leachate for stabilization assessment, and using four sets of lysimeter as experimental apparatus. Soild waste decomposition was accelerated in without leachate discharge system by sufficient moisture for methane bacteria. And gas production rate was between 54.2ℓ/kg VS∼335.9ℓ/kg VS in each lysimeter. Generation time of methane gas was showed different in each lysimeter, but it was much faster than literature research. The time of stabilization phase were began as follows : L-1 400 day, L-2 350 day, L-3 170 day and L-4 70 day respectively. Decreasing times of BOD/COD ratio and C/N ratio were necessary more than literature research because organic matter was not discharge such as wash out.
