Fugitive methane emissions from two experimental biocovers constructed with tropical residual soils: field study using a large flux chamber
(2019)
Abstract: This study aimed at assessing the response of two experimental passive methane
oxidation biocovers (PMOB) installed in a Brazilian landfill located in Guarapuava,
State of Paraná. The PMOBs covered an area of ...
Two novel biofilters to remove volatile organic compounds emitted by landfill sites
(2016)
Abstract: The present work investigates the potential of two experimental field columns (FC-2 and FC-4) to reduce volatile organic compound (VOC) emissions from a municipal solid waste (MSW) landfill located in Quebec, ...
Predicting the diversion length of capillary barriers using steady state and transient state numerical modeling: Case study of the Saint-Tite-des-Caps landfill final cover
(2015)
Abstract: Covers with capillary barrier effect (CCBE) have already been proposed to meet regulatory requirements for landfill final covers. Modeling of CCBE may be a relatively complex and time consuming task. Simpler, ...
Evaluation of methane oxidation in a landfill cover material using a simple indicator approach
(2011)
Abstract: Estimates of methane (CH4) oxidation rates (Rg) in biocovers are
crucial for development of abatement strategies. Rg values were estimated
in a landfill biocover with a simple approach based on gas diffusion ...
Methanotrophs and methanotrophic activity in engineered landfill biocovers
(2009)
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 ...
Determination of the soil water characteristic curve of highly compressible materials: Case study of pulp and paper by-product
(2004)
Abstract: A technique was developed for the determination of various points of the soil-water characteristic curve (SWCC)—including the air
entry value (AEV)—of compressible materials from one single test. The testing ...
Influence of capillary barrier effect on biogas distribution at the base of passive methane oxidation biosystems: Parametric study
(2016)
Abstract: The efficiency of methane oxidation in passive methane oxidation biosystems (PMOBs) is influenced by, among other things, the intensity and distribution of the CH4 loading at the base of the methane oxidation ...
Landfill gas distribution at the base of passive methane oxidation biosystems: Transient state analysis of several configurations
(2017)
Abstract: The design process of passive methane oxidation biosystems needs to include design criteria that account for the effect of unsaturated hydraulic behavior on landfill gas migration, in particular, restrictions to ...
Reduction of odours in pilot-scale landfill biocovers
(2014)
Abstract: Unpleasant odours generated from waste management facilities represent an environmental and societal concern. This multi-year study documented odour and total reduced sulfur (TRS) abatement in four experimental ...
Biocover performance of landfill methane oxidation: Experimental results
(2010)
Abstract: An experimental passive methane oxidation biocover (PMOB) was constructed within the existing final cover of the St-Nicéphore landfill. Its substrate consisted of a 0.80-m-thick mixture of sand and compost. The ...
