Abstract

 The purpose of this paper is estimation rate of odorous gas emission from landfills for simulating the odour dispersion. The method used for the study was based on the methane emission model of Intergovermental Panel on Climate change. This research has defined of reaction constants, fraction of  N and S in bulk waste, which had related to NH3, H2S and CH3SH generated. The study results show that there is no significant difference  between calculated and measured data of odorous gas emission, Nash-Sutcliffe coefficient index ranged from 0,642 to 0,887.
