Abstract
This study has been carried out to analyze the effects of leachate recirculation on methane gas concentration in the Landfill. The monthly average on precipitation of the landfill area during the period from 2010 to 2016 has been recorded at 130.9 mm and the total precipitation was recorded at 73.7 mm for the month of June in 2017. And based on the Korea meterological administration data obtained, the water content has been anticipated to be at low level. And for the control environment testing on the effects of leachate recirculation, the reading has been carried out in relation to the methane gas concentration with the landfill site tested with average reading of 30.14%. Once the reading has been established 5 tones of leachate has been injected and the readings carried out respectively with the first reading recorded at 24.66% on June with subsequent readings carried out, 31.51 (6/24), 36.88% (7/1) and final reading carried out on 7/25 registered at 52.47%. Based on the leachate recirculation, the test showed increase of methanate concentrations with the concentration percentage showing between 50~65%.
