“…For simplicity, previous studies have reported that the CH 4 oxidation process in landfill cover soils is accomplished by methanotrophic bacteria (Abushammala et al, 2012;Huber-Humer et al, 2008;Albanna et al, 2007;Stern et al, 2007;Kettunen et al, 2006). Methanotrophic bacteria (Fig.…”

“…Albanna et al (2007) reported that increasing the soil layer thickness from 15 to 20 cm increased the CH 4 oxidation values from 29% to 35% for a soil with 15% moisture content without nutrient addition, from 34% to 38% for a soil with a 30% moisture content without nutrient addition, and from 75% to 81% for a soil with a 30% moisture content with nutrient addition. However, in investigating the effect of bio-cover on CH 4 oxidation at the Leon landfill in Florida, Stern et al (2007) found that the efficiency of CH 4 oxidation can reach 64% with biocover utilization, while only 30% efficiency was reported for the control cell. Abichou et al (2009) reported that at the same landfill, an average of 79% of CH 4 was oxidized in the bio-cover system and 29% was oxidized in the control cell.…”

“…Several studies have shown that the CH 4 oxidation process in landfill cover is an efficient method of CH 4 emission mitigation (Abushammala et al, 2013a;Huber-Humer et al, 2008;Stern et al, 2007;Huber-Humer, 2004;Hilger and Humer, 2003;Humer and Lechner, 1999). This process takes place in many natural systems and soils without human interference, due to the abundance of several groups of bacteria requiring oxygen (O 2 ) for the oxidation process.…”

Migration of methane (CH 4 ) gas from landfills to the surrounding environment negatively affects both humankind and the environment. It is therefore essential to develop management techniques to reduce CH 4 emissions from landfills to minimize global warming and to reduce the human risks associated with CH 4 gas migration. Oxidation of CH 4 in landfill cover soil is the most important strategy for CH 4 emissions mitigation. CH 4 oxidation occurs naturally in landfill cover soils due to the abundance of methanotrophic bacteria. However, the activities of these bacteria are influenced by several controlling factors. This study attempts to review the important issues associated with the CH 4 oxidation process in landfill cover soils. The CH 4 oxidation process is highly sensitive to environmental factors and cover soil properties. The comparison of various biotic system techniques indicated that each technique has unique advantages and disadvantages, and the choice of the best technique for a specific application depends on economic constraints, treatment efficiency and landfill operations.

“…2). The chamber volume was 80 L, while the area was 0.4 m 2 (Stern et al 2007). The chamber area was chosen to meet the objectives of this study and was not so large that the environmental controls could not be assumed to be uniformly distributed over the enclosed surface area and not so small as to restrict the spatial variability of the emission rate.…”

Methane emissions and oxidation were measured during the wet and dry seasons at the Air Hitam, Jeram, and Sungai Sedu landfills in Malaysia. The resulting levels of methane emissions and oxidation were then modeled using the Inter-governmental Panel on Climate Change 1996 first order decay (FOD) model to obtain methane generation rate and potential values. Emissions measurements were performed using a fabricated static flux chamber. A combination of gas concentrations in soil profiles and surface methane and carbon dioxide emissions at four monitoring locations in each landfill was used to estimate the methane oxidation capacity.

“…Due to the molecular structure and stability of methane in the atmosphere (about 9 years), the global warming effect of this gas is about 20-25 times more than carbon dioxide (Ozcan et al 2007;Park and Shin, 2001;Zamorano et al, 2007). Studies showed that 3-19% of total global emissions of methane which was about 40Tg year -1 was produced in the landfills (Ozcan et al, 2007, Park and Shin, 2001, Wang-Yao et al, 2006, Zamorano et al, 2007 and this amount comprises about 10-19% of anthropogenic methane emissions (Stern et al, 2007). By using the methane gas in the landfills, we can reduce its greenhouse effects and also obtain a renewable source of energy (Machado et al, 2009;Park and Shin, 2001, Wang-Yao et al, 2006, Zamorano et al, 2007.…”

Landfilling has been considered as the most common method for solid waste disposal in developing countries which is faced with several issues, such as gas emission. Methane as a greenhouse gas is the main landfill gas which could be applied as a fuel for electrical power plants. In this study, the gas emission of Shiraz landfill site was predicted by using USEPA model, for this purpose, after determination of the solid waste physical composition on Shiraz landfill site, the L0 and k constants were estimated by Monte Carlo method, as well as the rate of gas collection and the rate of electrical power generation capacity were estimated under existing and ideal scenarios. The results showed that gas production would reach its peak up to 5.7×10 7 m 3 year -1 by 2039. The maximum electrical power generation was also similar to the pattern of gas production in the landfill and would be 2545GWh and 4019GWh for the existing and ideal conditions, respectively in 2039. Results showed that the recovery of biogas at Shiraz landfill could be a desirable alternative in different available waste management options for this city.
