“…A comparison of total silicon concentrations from biogas from digesters and landfill-derived biogas provide further evidence that the concentrations of silicon for landfill-derived biogas are considerably less than those in the biogas from digesters (Table 3). However, there is a trend evident to change from traditional landfills operating with temperatures of 25 8C (current, typical temperature conditions in landfill refuse in Canada) to 37 8C (a midtemperature for an operating bioreactor landfill) (McBean et al 2007). In response, the vapour pressures and hence the tendency for volatilization of siloxanes will also change.…”

Volatile methylsiloxanes and linear polydimethylsiloxanes (siloxanes), generated as components of biogases from digesters at wastewater treatment plants and solid waste landfills, have been identified as potentially causing significant operational problems. The problems are demonstrated as being an issue of ''sand in the transmission'' and are the reason for the changing of engine warrantees. Examples of monitored concentrations of siloxanes at a series of facilities are described, demonstrating degrees of variability both spatially and temporally, for different biogas sources. Wastewater digesters are shown to be generally producing biogases with higher siloxane concentrations than landfills. With a trend toward some landfills being operated as bioreactors, where the temperatures in the refuse are elevated to levels comparable to those within wastewater treatment digesters, there is potential that landfill-derived biogases may result in increased concentrations of siloxanes and hence more operating problems.Résumé : Les méthylsiloxanes volatils et les polydiméthylsiloxanes linéaires (siloxanes), des composantes de biogaz provenant de digesteurs d'usines de traitement des eaux et de sites d'enfouissement de déchets solides, ont été identifiés comme source potentielle de problèmes opérationnels. Les problèmes sont démontrés comme étant une question de « sable dans l'engrenage » et sont la raison des garanties de changement de moteurs. Les exemples de concentrations surveillées de siloxanes dans un ensemble d'installations sont décrits, démontrant divers niveaux de variabilité dans l'espace et dans le temps pour différentes sources de biogaz. Il est démontré que les digesteurs d'eaux usées produisent des biogaz à concentration plus élevée de siloxanes que les sites d'enfouissement. Avec la tendance actuelle d'exploiter certains sites d'enfouissement comme des bioréacteurs où les températures des déchets sont élevées à des niveaux similaires à ceux des digesteurs de traitement des eaux usées, il est possible que les biogaz des sites d'enfouissement augmentent les concentrations de siloxanes, générant ainsi plus de problèmes opérationnels.

“…Solid waste management, in its broadest sense, is concerned with the generation, on-site storage, collection, transfer, transportation, process and recovery and disposal of solid wastes (Whiteman, Smith and Wilson, 2001;Coad, 2000;Cointreau-Levine, 2000;McBean et al, 1995). Nowadays, nations throughout the world are attempting to develop approaches of sustainable management of household and industrial wastes.…”

The extent and scope of understanding the nexus between poverty and environment are so extensive as well as complex that existing studies do not provide a concrete answer to the paradox. In the same vein, this study aims to contribute further to extent literature by assessing the attitude and behavior of the urban impoverished population concerning their management of solid wastes at household level. It also determines the factors that could potentially affect their willingness to pay for an improved access to solid waste collection and disposal services in their residential areas. The empirical findings obtained through some statistical and econometric analyses do not actually support the widely voiced assertion that the poor populations degrade the environment. But the findings strongly support the fact that urban impoverished populations do not actually degrade but they protect the environment by undertaking some environment-friendly waste management practices and contributing monetarily for an improvement in the environmental quality.

“…Among these, biological reactions are the most important factor for LFG generation. Organic matter decomposition takes place in three primary stages: aerobic decomposition, acid-phase nonmethanogenic anaerobic decomposition, and anaerobic methanogenic decomposition (McBean et al, 2007). Different authors indicate that the third stage can be divided into an anaerobic methanogenic unsteady stage, where methane (CH 4 ) increases and nitrogen (N 2 ) and carbon dioxide (CO 2 ) decrease to their terminal values, and an anaerobic methanogenic steady stage, where the generation of CH 4 and CO 2 remains relatively constant (Farquhar and Rovers, 1973).…”

Technical and economic evaluation of biogas capture and treatment for the Piedras Blancas landfill in Córdoba, Argentina

Methane has 21 times more greenhouse gas potential than carbon dioxide. Because of that, it is of great importance to adequately manage biogas emissions from landfills. In addition, it is environmentally convenient to use this product as an alternative energy source, since it prevents methane emissions while preventing fossil fuel consumption, minimizing carbon dioxide emissions. Performed analysis indicated that biogas capturing and energy generation implies 3 times less equivalent carbon dioxide emissions; however, a change in the Argentinean electrical market fees are required to guarantee the financial feasibility of the project.
