A simple field method to qualify the state of saturation in capillary barriers
Abstract: A simple and straightforward field method to rapidly qualify the state of saturation of moisture retaining layers (MRL) is proposed and the details of its calibration and operation, described. The technique is ...
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
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
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 ...
Evaluation of the effectiveness of a cover with capillary barrier effect to control percolation into a waste disposal facility
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 ...
Evaluation of methane oxidation efficiency of two biocovers: Field and laboratory results
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 ...
Water retention curve and hydraulic conductivity function of highly compressible materials
Other titre : Courbe de rétention d’eau et fonction de conductivité hydraulique des matériaux hautement compressibles
Abstract: A model capable of describing the suction-induced consolidation curve (void ratio function) and water retention curve (WRC) of highly compressible materials (HCM) is developed, validated and finally applied to ...
Biotic methane oxidation within an instrumented experimental landfill cover
Other titre : Methane oxidation within an experimental landfill cover
Abstract: An experimental landfill cover composed of a mixture of sand and compost was installed at the St-Nicéphore landfill in Québec (Canada). The mixture was evaluated as a potential substrate to promote methane (CH4) ...
Quantifying microbial methane oxidation efficiencies in two experimental landfill biocovers using stable isotopes
Abstract: Stable isotope analyses were performed on gas samples collected within two instrumented biocovers, with the goal of evaluating CH4 oxidation efficiencies (f0). In each of the biocovers, gas probes were installed ...
Can soil gas profiles be used to assess microbial CH4 oxidation in landfill covers?
Abstract: A method is proposed to estimate CH(4) oxidation efficiency in landfill covers, biowindows or biofilters from soil gas profile data. The approach assumes that the shift in the ratio of CO(2) to CH(4) in the gas ...
Evolution of biodegradation of deinking by-products used as alternative cover material
Abstract: Deinking by-products (DBP) have been used as alternative material for the construction of cover systems for municipal waste disposal facilities and acid-producing mine residues. Considering the high organic ...
