A mixture of gases and obnoxious odours are major components of landfill emission. A dispersion modelling on air pollutants and odour emissions anticipated from a proposed Integrated Waste Management Facility was conducted considering five operating scenarios. Impacts of the predicted ground level concentrations of air pollutants (including carbon monoxide, CO; oxides of nitrogen, NO_X; sulphur dioxide, SO₂; particulate matter, PM and hydrocarbons, HC) and odour on ambient air quality were investigated using the 10-min 1 OU/m³ odour limit, CH₄ Lower Explosive Limit (LEL) and the daily limits of CO, NOx, SO₂, PM and HC. The anticipated maximum ground level concentration of emitted odour and CH₄ are 0.0040 OU/m³ and 0.0349 ppm, respectively. Simultaneous operations of all the major components of the facility will generate the daily maximum concentrations of 7.34, 2.60, 7.31, 29.72 and …
