Abstract/Description: Environment and natural resources can be polluted and consequently human beings, animals and plants can be impacted. Then, waste management plays an important role in human's life. Landfilling is one of the most common technology for solid waste management (MSW) as an alternative to waste burning and composting. A complex series of biological and chemical reactions is initiated with the burial of solid waste in a landfill, resulting in the production of methane (CH4) and carbon dioxide (CO2) as the major end products of biological decomposition. With a global warming potential 25 times as high as than carbon dioxide on a century time scale, methane is an important greenhouse gas in the climate system. The fate of this CH4 varies widely depending on typical landfill practice in a specific country. Ideally, all generated CH4 would be captured and used beneficially as an energy source. However, even at modern landfills, some CH4 is released before installation of gas collection systems and some CH4 is released because it is not captured in a collection system. A fraction of the uncollected CH4 is oxidized in the landfill cover through bacterial activities and the rate of CH4 oxidation has recently been reviewed. Thus, estimation of methane emissions from landfills is a crucial task. Several models have been developed through the history for such a task, however, none of them represent the reality of the different phases that methane goes through in the landfill. Moreover, methane oxidation capacity estimation has been only based on stable isotopes method. The objective of this work is to develop new methodologies to quantify methane oxidation capacity within landfill covers and to develop a holistic gas estimation model based on the different phases that gas goes through, generation, collection and oxidation, and this model will be calibrated based on field measurements and historical data available over the United States.
