“…Compost, made from mature yard wastes yielded the best results with EC up to 590 g m -2 d -1 and at values for X of between 90 and 100%, during more than 100 days of continuous filter operation (Haubrichs and Widmann 2006). Compost, made from dead leaves, also yielded good results Wilshusen et al 2004). In addition, the time required to reach 100%, conversion is less for the mature compost than that for freshly generated compost, being some 15 and 55 days respectively.…”

The production of biogas in landfills, its composition and the problems resulting from its generation are all reviewed. Biofiltration is a promising option for the control of emissions to atmosphere of the methane contained in biogas issued from the smaller and/or older landfills. A detailed review of the methane biofiltration literature is presented. The microorganisms, mainly the methanotrophs, involved in the methane biodegradation process, and their needs in terms of oxygen and carbon dioxide utilization, are described. Moreover, the influence of nutrients such as copper, nitrogen and phosphorus, and the process operating conditions such as temperature, pH and moisture content of the biofilter bed, are also presented. Finally, the performance of various filter beds, in terms of their elimination capacities, is presented for laboratory scale biofilters and landfill covers.

“…LFG treatment using a variety of types of biotic systems, including bio-washers (Figueroa, 1996), biomembranes (Figueroa, 1996), bio-filters (Huber- Humer et al, 2008;Gebert and Grongroft, 2006a;Wilshusen et al, 2004b;Streese and Stegmann, 2003;Figueroa, 1996), bio-windows (Huber- Humer et al, 2008), biocovers (Shangari and Agamuthu, 2012;Huber-Humer et al, 2008) and bio-tarps (Huber- Humer et al, 2008), has been discussed in the literature. The first two types of systems (bio-washers and bio-membranes) for landfill emissions treatment are not discussed in this section because of their limited use.…”

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.

“…As seen from Table 1, up to 100% of CH 4 emissions from landfi ll can be oxidized to CO 2 and H 2 O, if landfi ll cover is well designed and constructed. The maximum methane oxidation capacity measured in bed layer (60-80 cm depth) at laboratory and fi eld scales ranged from 200 to 400 g m -2 d -1 [34][35][36][37]. Under certain conditions, methanotrophs in landfi ll cover not only oxidize the CH 4 produced from landfi ll, but also consume atmospheric CH 4 [38][39].…”

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.
