“…Both methanogens and CH 4 -oxidising bacteria (MOB) are present in solid manure (Sharma et al, 2011). There are few studies on the potential for CH 4 oxidation, but MOB population dynamics during composting and maturation phases have been described for other organic residues (Wilshusen et al, 2004;Halet et al, 2006), and thus MOB activity may play a role in mitigating CH 4 emissions from solid manure, as proposed by Szanto et al (2007).An organic surface crust is often present on livestock slurry stores, which may contain a significant potential for CH 4 oxidation (Ambus and Petersen, 2005;Petersen et al, 2005;Hansen et al, 2009). However, Nielsen et al (2013) found that potential methane oxidation (PMO) in two natural crusts from piggeries remained low until late autumn, indicating that MOB activity was low during summer and early autumn where most of the annual emissions occur (Husted, 1994).…”

Ongoing intensification and specialisation of livestock production lead to increasing volumes of manure to be managed, which are a source of the greenhouse gases (GHGs) methane (CH 4 ) and nitrous oxide (N 2 O). Net emissions of CH 4 and N 2 O result from a multitude of microbial activities in the manure environment. Their relative importance depends not only on manure composition and local management practices with respect to treatment, storage and field application, but also on ambient climatic conditions. The diversity of livestock production systems, and their associated manure management, is discussed on the basis of four regional cases (Sub-Saharan Africa, Southeast Asia, China and Europe) with increasing levels of intensification and priorities with respect to nutrient management and environmental regulation. GHG mitigation options for production systems based on solid and liquid manure management are then presented, and potentials for positive and negative interactions between pollutants, and between management practices, are discussed. The diversity of manure properties and environmental conditions necessitate a modelling approach for improving estimates of GHG emissions, and for predicting effects of management changes for GHG mitigation, and requirements for such a model are discussed. Finally, we briefly discuss drivers for, and barriers against, introduction of GHG mitigation measures for livestock production. There is no conflict between efforts to improve food and feed production, and efforts to reduce GHG emissions from manure management. Growth in livestock populations are projected to occur mainly in intensive production systems where, for this and other reasons, the largest potentials for GHG mitigation may be found.Keywords: methane, nitrous oxide, storage, treatment, farm model ImplicationsLivestock manure is a source of greenhouse gas (GHG) emissions, mainly as methane and nitrous oxide. GHG emissions are biogenic and regulated by manure characteristics, and therefore emissions can be manipulated via handling, treatment and storage conditions. Globally, livestock production systems vary widely, and this is also true for GHG mitigation potentials, but generally efforts to conserve nutrients in manure for crop production will also reduce GHG emissions. Future growth in livestock production is projected to occur mainly in confined animal feeding operations, which also appear to have the greatest potential for GHG mitigation. IntroductionSince the mid 20th century, there has been a growing pressure on land resources for production of food and feed for livestock and, increasingly, crops for energy production (Hoogwijk et al., 2005). To fulfil the demand for meat, milk and eggs, livestock production in developing countries is expanding, especially in peri-urban areas (Gerber et al., 2005), and worldwide becomes more specialised (Steinfeld et al., 2006). In consequence of these trends, increasing volumes of livestock manure are produced, which are a source of greenhouse gases (GHGs) contributing t...

“…The major controlling environmental factors governing the CH 4 oxidation process in landfill cover soils, such as soil texture, organic content, moisture content, temperature, pH, nutrients, and O 2 and CH 4 concentrations (Wilshusen et al, 2004a;Börjesson et al, 2001;Boeckx et al, 1996) are briefly discussed in this section. Applying knowledge about these controlling factors can optimize the process of mitigating CH 4 emissions from landfills.…”

“…Visvanathan et al (1999) found that higher soil organic contents resulted in higher CH 4 oxidation rates in column assays. High-organic-content materials, such as compost, are widely used in landfill cover systems to enrich their CH 4 oxidation capacity (Abichou et al, 2009;HuberHumer et al, 2008;Gebert and Grongroft, 2006a;Wilshusen et al, 2004a;Streese and Stegmann, 2003). Materials with high organic contents, high levels of nutrients, and high porosity have been proven to have high CH 4 oxidation capacities, which in some cases, tends to oxidize atmospheric CH 4 .…”

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.

Municipal solid waste (MSW) includes packaging waste, yard waste, wood, textile, newsprints, bottles, food waste, metals, and plastics. Trade, industry, and human population growth plus variations in living standards and in consumption patterns have been the main factors for progressive increase in generating MSW. As a consequence, management of MSW is one of the major challenges for municipalities in the 21st century [1][2]. In developing Asian countries, these factors are Pol. J. Environ. Stud. Vol. 26, No. 3 (2017) AbstractThis paper evaluates the environmental impacts of various municipal solid waste (MSW) treatment options produced on-site simultaneously with energy and material recovery. The results present a comparison of life cycle assessment (LCA) for municipal solid waste management (MSWM) in five different waste scenarios along with baseline scenario of the Defence Housing Authority (DHA) in Lahore. All scenarios were modeled using EaseTech software. Nine impact categories were assessed and results were presented based on the ASTM D5231-92(2003) characterization method. Results revealed that a material recovery facility (MRF) had low global warming potential (GWP), but lower avoided burdens in other impact categories. The incineration process indicated fewer burdens on the environment such as GWP (-2.086×10 7 kg CO 2 eq) as compared to landfills (2.461×10 7 kg CO 2 eq). This was due to lower avoided emissions in the landfill process compared to incineration. The negative values in results represented higher avoided emissions in treatment processes. Bio-gasification avoided CO 2 emissions (-8.053×10 5 kg CO 2 eq), but showed negative impacts in other categories. Almost all impact categories were high in composting except for freshwater eutrophication. LCA results provided good knowledge for decision makers as a tool to decide what alternative is a better change for sustainable waste management.
