Evaluation of gaseous pollutants emission rate from marvdasht landfills

ABSTRACT

Unmanaged gasses emitted from the landfills can lead to various environmental and health problems for the resident of such regions. Despite various studies conducted on prediction of emission rates of gaseous pollutant in landfills, no study in currently being conducted on the emission rates of carbon dioxide, methane, and non-methane organic compounds from the Marvdasht landfills. In the first steps of this study the required information were gathered first and then the necessary prediction calculations were handled by the LandGEM software. The study results suggest that the within the years of 2003 and 2031, the generation rates of carbon dioxide, methane and non-methane organic compounds will respectively be equal to 14×10[11], 4667×10[7] and 3.89×10[5] tons. Among the aforementioned gasses, in case of converting the methane energy capacity into the electrical energy, a total income of 1489 billion rials is achievable from the Marvdasht landfill within a course of 27 years of operation. However, it should be noted that no investigation was conducted on the initial and operation costs in this study. In this study, by calculating all of the required information for the design and construction of a biogas collection and extraction system in the landfill of Marvdasht, the necessary means for the appliance of such plan has been provided
