Abstract :
Nowadays, the population increase in line with the technology advances has improved life and thus has caused a rapid increase in consumption and eventually led to a huge increase of wastes. So that, the production of these materials has created a huge environmental disaster in human societies in recent years which is considered as one of the major challenges facing humanity. In recent years, especial equipment is used to collect, manage and transfer gas in landfills. Collecting landfill gas (biogas) have different benefits in environmental fields, economic and , the most important, energy. The biogas produced by urban Landfill has a high proportion of volatile organic methane that damages the ozone layer. Landfill gases are produced through a collection of biochemical reactions on biodegradable organic matter present in the waste in anaerobic conditions. These gases include methane, carbon dioxide hydrogen, hydrogen sulfide, volatile organic compounds and so on. Assessment and prediction of production rates and factors affecting gas emissions from landfill are critical for landfill designing and successful utilization of the gases as an energy source. Thus, the present paper has studied these matters.
