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 ...
Methodology to determine the extent of anaerobic digestion, composting and CH4 oxidation in a landfill environment
(2018)
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 ...
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 ...
Examination of the effects of solids content on thickened gold mine tailings sedimentation and self-weight consolidation
(2019)
Abstract: Thickening is being increasingly adopted by the mining industry because of its
economic and environmental attributes, such as decreased amounts of water
released following deposition and a smaller footprint of ...
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 ...
Experimental study and numerical reproduction of self-weight consolidation behavior of thickened tailings
(2014)
Abstract: Thickened tailings, defined as mineral wastes that behave as a non-Newtonian fluid, show a small yield stress and release a small amount of water following deposition. Thickening has become an increasingly used ...
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 ...
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 ...
