Methodology to determine the extent of anaerobic digestion, composting and CH4 oxidation in a landfill environment
Abstract: An examination of the processes contributing to the production of landfill greenhouse gas (GHG) emissions is required, as the actual level to which waste degrades anaerobically and aerobically beneath covers has ...
Methanotrophs and methanotrophic activity in engineered landfill biocovers
Abstract: The dynamics and changes in the potential activity and community structure of methanotrophs in landfill covers, as a function of time and depth were investigated. A passive methane oxidation biocover (PMOB-1) was ...
Effects of preconditioning the rhizosphere of different plant species on biotic methane oxidation kinetics
Abstract: The rhizosphere is known as the most active biogeochemical layer of the soil. Therefore, it could be a beneficial environment for biotic methane oxidation. The aim of this study was to document - by means of batch ...
Microbial methane oxidation at the Fíflholt landfill in Iceland
Abstract: Methane oxidizing biosystems have received wide recognition in recent years as a cost effective and important means to reduce emissions from landfills. However, there is no documentation of the oxidation ...
Quantifying microbial methane oxidation efficiencies in two experimental landfill biocovers using stable isotopes
Abstract: Stable isotope analyses were performed on gas samples collected within two instrumented biocovers, with the goal of evaluating CH4 oxidation efficiencies (f0). In each of the biocovers, gas probes were installed ...
Modeling methane migration and oxidation in landfill cover materials with TOUGH2-LGM
Abstract: Methane oxidation within a Passive Methane Oxidation Barrier (PMOB) and the downward migration of molecular O2, whose presence is necessary for the oxidation reaction to occur, were simulated using the finite ...
Evaluating methane oxidation efficiencies in experimental landfill biocovers by mass balance and carbon stable isotopes
Abstract: Biocovers are an alternative for mitigating fugitive and residual emissions of methane from landfills. In this study, we evaluated the performance of two experimental passive methane oxidation biocovers (PMOBs) ...
Biotic methane oxidation within an instrumented experimental landfill cover
Other titre : Methane oxidation within an experimental landfill cover
Abstract: An experimental landfill cover composed of a mixture of sand and compost was installed at the St-Nicéphore landfill in Québec (Canada). The mixture was evaluated as a potential substrate to promote methane (CH4) ...
