Rapid methane oxidation in a landfill cover soil.
Methane oxidation rates observed in a topsoil covering a retired landfill are the highest reported (45 g m day) for any environment. This microbial community had the capacity to rapidly oxidize CH(4) at concentrations ranging from <1 ppm (microliters per liter) (first-order rate constant [k] = -0.54 h) to >10 ppm (k = -2.37 h). The physiological characteristics of a methanotroph isolated from t...
متن کاملCharacteristics of Biochar-Amended Soil Cover for Landfill Gas Mitigation
In this study, biochar-amended soil cover was investigated to enhance reduction of CH4 emissions from landfills. This paper presents physical and chemical characteristics of biochar-amended soils. Specifically, moisture content, organic content, ash content, pH, particle size distribution, Atterberg limits, specific gravity, and permeability tests were conducted with biochar alone, soil alone, ...
متن کاملModeling of Methane Migration and Oxidation in Biochar-amended Landfill Cover Soil
The global warming potential (GWP) of methane (CH4) is 25 times the GWP of carbon dioxide (CO2); as such, controlling CH4 emissions at municipal solid waste (MSW) landfills is an urgent task. Oxidation of CH4 using soil covers and bio-enhanced covers as a CH4 mitigation strategy is receiving great attention from environmental professionals. Biochar-amended soil covers are proposed to effectivel...
متن کاملUtilisation of chemically stabilized arsenic-contaminated soil in a landfill cover
The aim of the study was to determine if an As-contaminated soil, stabilized using zerovalent iron (Fe(0)) and its combination with gypsum waste, coal fly ash, peat, or sewage sludge, could be used as a construction material at the top layer of the landfill cover. A reproduction of 2 m thick protection/vegetation layer of a landfill cover using a column setup was used to determine the ability o...
متن کاملAbove- and below-ground methane fluxes and methanotrophic activity in a landfill-cover soil.
Landfills are a major anthropogenic source of the greenhouse gas methane (CH(4)). However, much of the CH(4) produced during the anaerobic degradation of organic waste is consumed by methanotrophic microorganisms during passage through the landfill-cover soil. On a section of a closed landfill near Liestal, Switzerland, we performed experiments to compare CH(4) fluxes obtained by different meth...
