Fugitive methane emissions from two experimental biocovers constructed with tropical residual soils: field study using a large flux chamber
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
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, ...
Reduction of odours in pilot-scale landfill biocovers
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 ...
Evaluation of the efficiency of an experimental biocover to reduce BTEX emissions from landfill biogas
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 ...
Biocover performance of landfill methane oxidation: Experimental results
Abstract: An experimental passive methane oxidation biocover (PMOB) was constructed within the existing final cover of the St-Nicéphore landfill. Its substrate consisted of a 0.80-m-thick mixture of sand and compost. The ...
Methodology to determine the extent of anaerobic digestion, composting and CH4 oxidation in a landfill environment
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 ...
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 ...
Dynamics and diversity of methanotrophs within an experimental landfill cover
Other titre : Diversity and dynamics of methanotrophs within an experimental landfill cover soil
Abstract: Three experimental biocovers were installed during the summer of 2006 at the St‐Nicéphore landfill in Québec (Canada). The main objectives of the experimental program were to assess the efficiency of these biocovers ...
Energy generation from municipal solid waste and the current scenario of biogas recovery in Brazil
Other titre : Geração de energia a partir de resíduos sólidos urbanos e o panorama atual da recuperação de biogás no Brasil
Abstract: The landfill is a method of treatment and final disposal of municipal solid waste (MSW) widely employed all over the world, mainly in developing countries. The biogas released from landfills raises environmental ...
Análise por componentes principais para o volume de biogás gerado em aterro sanitário e a correlação com variáveis físico-químicas
Other titre : Principal component analysis (PCA) to the volume of biogas generated in landfill and the correlation with physico-chemical parameters
Resumo: O presente estudo teve como objetivo avaliar a estrutura de correlação do volume de biogás gerado com as variáveis físico-químicas umidade, pH, alcalinidade, demanda química de oxigênio (DQO) e sólidos totais ...
