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, ...
Biofiltration of methane from cow barns: Effects of climatic conditions and packing bed media acclimatization
(2018)
Abstract: The performance of biofiltration to mitigate CH4 emissions from cow barns was investigated in the laboratory using two flow-through columns constructed with an acclimatized packed bed media composed of inexpensive ...
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 ...
Elements of design of passive methane oxidation biosystems: Fundamental and practical considerations about compaction and hydraulic characteristics on biogas migration
(2018)
Abstract: Passive methane oxidation biosystems (PMOBs) are often proposed as a means to reduce fugitive landfill CH4 emissions, i.e. emissions not captured by gas collection systems. However, current designs may lead to ...
Effects of preconditioning the rhizosphere of different plant species on biotic methane oxidation kinetics
(2016)
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 ...
Optimization of a landfill gas collection shutdown based on an adapted first-order decay model
(2017)
Abstract: LandGEM’s equation was reformulated to include two types of refuse, fast decaying refuse (FDR) and slow decaying refuse (SDR), whose fractions and key modeling parameters k and L0 were optimized independently for ...
Microbial methane oxidation at the Fíflholt landfill in Iceland
(2014)
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 ...
Evaluation of the efficiency of an experimental biocover to reduce BTEX emissions from landfill biogas
(2014)
Abstract: Landfill emissions include volatile organic compounds (VOCs) and, particularly, benzene, toluene, ethyl-benzene and xylene isomers (collectively called BTEX). The latter are the most common VOCs found in landfill ...
