“…An exponential increase in CH 4 oxidation rate was observed in response to temperatures ranging from 4-30°C [18]. Further increase in temperature leads to rapidly declined CH 4 oxidation rate.…”

“…Previous studies have revealed that the type and physical-chemical properties of cover materials (e.g. particle size, porosity, moisture, and organic matter content) have a multi--dimensional effect on gas transfer and distribution, methane and oxygen availability, methanotrophs community structure and population, and nutrients supply [18,[54][55]. He et al [54] investigated the CH 4 oxidation capacities and microbial community structures for two types of cover materials: a stabilized waste and an ordinary landfi ll cover material (clay soil).…”

“…Factors infl uencing CH 4 oxidation performance in landfi ll include cover materials (type and physical-chemical properties), landfi ll gas fl ux (particularly CH 4 concentration), O 2 availability, landfi ll vegetation and climatic variables [17][18][19][20][21] . The present work presents a brief overview on CH 4 oxidation potential in landfi ll cover, main limiting factors and their underlying effect mechanism.…”

Uncontrolled emissions of landfi ll gas may contribute signifi cantly to climate change, since its composition represents a high fraction of methane, a greenhouse gas with 100-year global warming potential 25 times that of carbon dioxide. Landfi ll cover could create favourable conditions for methanotrophy (microbial methane oxidation), an activity of using bacteria to oxidize methane to carbon dioxide. This paper presents a brief review of methanotrophic activities in landfi ll cover. Emphasis is given to the effects of cover materials, environmental conditions and landfi ll vegetation on the methane oxidation potential, and to their underlying effect mechanisms. Methanotrophs communities and methane oxidation kinetics are also discussed. Results from the overview suggest that well-engineered landfi ll cover can substantially increase its potential for reducing emissions of methane produced in landfi ll to the atmosphere.

“…Apart from clay and soil, some synthesized and alternative biological landfill covers that contain active materials, have been applied as alternative landfill covers, such as agriculture soil, horticulture soil, compost, sand, peat and mechanical-biological treatment residues (Barlaz et al, 2004;Humer and Lechner, 2001;Einola et al, 2008;Stern et al, 2007). Aged refuse and sewage sludge are also considered promising materials for the mitigation of CH 4 emissions because they are cost-effective bio-cover materials and have a high CH 4 oxidation capacity (Barlaz et al, 2004;Wang et al, 2011).…”

“…Many studies have focused on how to promote methane oxidation potential (MOP) when using aged refuse or sewage sludge as bio-covers (Kightley et al, 1995;Barlaz et al, 2004;Hilger and Humer, 2003;Huber-Humer et al, 2008;Einola et al, 2008;Wang et al, 2011). However, less is known about the influence of a mixture of aged refuse and sewage sludge on microbial CH 4 oxidation.…”

This study looks at the annual variations in landfill gas concentrations within the surface layer of the dump as well as the effect of climatic factors on these variations under the tropical climate. The experiment was carried out at part of the Karadiyana landfill, Sri Lanka, containing old mixed municipal solid waste covered by vegetation. The gas concentrations of the landfill surface layer were measured from three gas wells established on the dump surface layer, which contains 2.5 m depth, throughout the year with the measuring of climatic factors. The results show the annual fluctuation of temperature, cumulative rainfall, relative humidity, and atmospheric pressure were 27–42°C, 66.7–357.7 mm, 24.7%–78.2%, and 999.5–1014 mbar around the studied landfill area, and the average concentration value of the CH4, NH3, H2S, and VOCs gases were 18.94 ± 11.49%, 15.48 ± 15.17 mg m−3, 15.06 ± 19.02 mg m−3, and 0.83 ± 0.99 mg m−3, respectively. The rainfall and atmospheric temperature were significant metrological factors influencing the surface layer gas concentrations and showed a significant positive correlation with cumulative rainfall and a negative correlation with atmospheric temperature. The relative humidity shows a moderate positive correlation, and there was no evidence of a considerable impact of atmospheric pressure on the surface layer concentrations. Annual fluctuation is a critical factor for landfill gas emission quantification, and surface layer concentration variation can be used to study the emission fluctuation by considering their relationship.
