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 ... -
Evaluation of the effectiveness of a cover with capillary barrier effect to control percolation into a waste disposal facility
(2011)Abstract: The goal of an instrumented experimental plot constructed on the Saint-Tite-des-Caps landfill site was to evaluate the field behaviour and the performance of a cover with capillary barrier effect (CCBE) to ... -
Assessment of the design of an experimental cover with capillary barrier effect using 4 years of field data
(2011)Abstract: One important step in the design of inclined covers with capillary barrier effect (CCBE) is the determination of the water diversion length (DL). Numerical simulations can predict the DL more precisely than ... -
Evaluation of methane oxidation efficiency of two biocovers: Field and laboratory results
(2012)Abstract: Biocovers constitute a promising technology to reduce fugitive and residual emissions from landfills throughout their operational life and after gas collection systems are turned off. The aim of this study was ... -
Effect of composts, nitrogen salts and NPK fertilizers on methane oxidation potential at different temperatures
Other titre : Effects of compost, nitrogen salts and fertilizers on methanotrophic activity(2012)Abstract: The effects of compost, nitrogen salts, and nitrogen-phosphorous-potassium (NPK) fertilizers on the methane oxidation potential (MOP) of landfill cover soil at various temperatures were assessed. For this, we ... -
Evaluating methane oxidation efficiencies in experimental landfill biocovers by mass balance and carbon stable isotopes
(2012)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) ... -
Does vegetation affect the methane oxidation efficiency of passive biosystems?
(2015)Abstract: It is often reported in the technical literature that the presence of vegetation improves the methane oxidation efficiency of biosystems; however, the phenomena involved and biosystem performance results are still ... -
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 ... -
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 ... -
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 ... -
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 ... -
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, ... -
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 ... -
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, ... -
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 ... -
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 ... -
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 ...
