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 ...

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, ...

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 ...

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 ...

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 ...

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 ...

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) ...

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 ...

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 ...

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 ...
