Appropriate management of waste landfills is required worldwide, including in developing countries. Early stabilization of landfills and reduction of environmental pollution by leachate is recognized as an important issue [1]. In most developing countries, landfill leachate is treated in stabilization ponds [2]. Leakage or overflow of untreated leachate to the surrounding environment is a concern, with large volumes of landfill leachate being produced by extensive landfill areas with high seasonal rainfall. Leachate recirculation in landfill bodies is an attractive technology that can reduce the volume of leachate and attenuate pollutants in the leachate by degradation in the landfill body [3,4]. Leachate recirculation is a process known to enhance the biodegradation of organics in waste and leachate, especially in arid regions, since it contributes moisture and extends the retention time [1,5–7]. Recently, a decrease in the biodegradation rate in the dry season in the tropics was reported [8], and Sanphoti et al. [9] reported that leachate recirculation with supplemental water enhanced stabili- zation in a simulated landfill reactor in a tropical region. In this context, leachate recirculation in waste landfills in tropical regions might improve both the handling of leachate in the rainy season and enhance the degradation of wastes in the dry season.
