The amount of methane emitted from landfills to the atmosphere is controlled by the type of cover layer on the landfill. The methane flux measurements were performed using a static chambre technique. The objective of this study was to estimate the emissions of methane from the landfill surfasse. The results show that fugitive emissions of methane into the atmosphere are 18.66 g/m2/ day to 149.86 g/m2/day, representing 31.4% of the total methane production in the landfill. The gas capture efficiency in the landfill was 68.6%. The fugitive emission is the result of the inefficiency of the gas capture system in the landfill.
