Abstract:
The objective of this study is to determine the effects of leachate recirculation on methane production and waste decomposition. The waste from Knongkham transfer station, Bangkok, Thailand, was used for a representative of MSW. The study was conducted by constructing two simulated landfill reactors. One reactor was operated as a control without leachate recirculation (RC) and the other served as experimental reactor with leachate recirculation (R1). sodium Bicarbonate, in order to maintain buffer capacity, was added to both reactors. At the first step, leachate was recirculated for accelerate waste decomposition. The leachate recirculation was carried out until the waste in the reactors were stabilized. At the second step, the leachate from fresh-waste was introduced into both reactors with stepwise OLR increasing. The results indicated that leachate recirculation help accelerate MSW stabilization as well as enhance gas production in simulated landfill. In addition, increasing in OLR could produced higher methane production
