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, ...
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 ...
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 ...
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 ...
Power generation and gaseous emissions performance of an internal combustion engine fed with blends of soybean and beef tallow biodiesel
(2016)
Abstract: This study aimed to compare the performance of an internal combustion engine fed with blends of biodiesel produced from soybean and diesel, and blends of biodiesel produced from beef tallow and diesel. Performance ...
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 ...
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, ...
