“…The first group is the concentration measurements of select odorants by means of complex physical and chemical analyses, based on the qualitative and quantitative measurement of air samples [21], for example: gas and gas-liquid chromatography, infrared, and mass spectroscopy [22][23][24]. Another chemical-physical method is measurement with the use of an "electronic nose, " an analytical tool that allows quick identification of chemicals through the imitation of the biological mechanism of smell.…”

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 concerns, as it contributes to the greenhouse effect, due to its high content of methane and carbon dioxide, and in relation to the potential damage to health caused to the surrounding populations of these areas. However, biogas has a great energy potential, representing economic and environmental advantages, making the waste disposal in landfills more sustainable in relation to these economic and environmental aspects. In Brazil, few landfills are technically prepared in recovering energy from biogas, which may be encouraged by the new Solid Waste National Policy, which aims to fit the landfills to the technical criteria of engineering, as well as to provide appropriate instructions on the waste management throughout its life cycle. The present review deals with the process of biogas generation based on municipal solid waste and some techniques that provide quantitative data on the biogas emission, and also the current scenario in Brazil related to the energy recovery from such source of bioenergy and its future potentialities. Keywords: Energy potential; landfill; biogas. ResumoO aterro sanitário é um método de tratamento e disposição final para os resíduos sólidos urbanos (RSU), largamente utilizado em todo o mundo, sobretudo nos países em desenvolvimento. O biogás emitido em aterros sanitários desperta grande preocupação ambiental, já que contribui para as emissões intensificadoras do efeito estufa, pelo seu alto conteúdo de metano e dióxido de carbono, e também quanto aos danos potenciais à saúde das populações circunvizinhas aos aterros, além do incômodo olfativo. No entanto, esse gás possui grande potencialidade para uso energético, o que apresenta vantagens econômicas e ambientais, tornando a disposição do lixo em aterros mais sustentável do ponto de vista econômico e ambiental. No Brasil, poucos aterros estão preparados tecnicamente para a recuperação energética do biogás, o que deve ser impulsionado pela nova Política Nacional de Resíduos Sólidos, que visa adequar os aterros quanto aos critérios técnicos de Engenharia, bem como orientar a gestão do lixo em todo o seu ciclo de vida. Este trabalho aborda o processo da geração de biogás a partir de resíduos sólidos urbanos e algumas das técnicas que permitem estimar quantitativamente essas emissões, bem como o atual panorama brasileiro referente à recuperação energética dessa forma de bioenergia e potencialidades futuras. Palavras-chave: Aproveitamento energético; aterro sanitário; biogás.

“…In addition to the complexity created by the relative juxtaposition of odor sources and receptors, the characteristics of odor emissions can change during different operation times of treatment facilities (De Feo et al, 2013), which further increases the complexity of source identification. Until now, although the odor emissions from individual composting plants (Cadena et al, 2009), landfill sites (Capelli et al, 2008;Romain et al, 2008;Saral et al, 2009;Scaglia et al, 2011;Ding et al, 2012;Li et al, 2013), and transfer stations (Fang et al, 2013b) have been separately investigated, little research has been done on the interactive influence of odors from multiple sources at MSW facilities (Dorado et al, 2013).…”

An integrated approach was applied to identify the key odorants comprising emissions from different zones in two adjacent waste treatment facilities (an aerobic biological treatment plant and an anaerobic landfill site), identify their precise sources, and distinguish the interactive influences between them. Seven odor families were investigated, including alcohols, terpenes, carbonyls, aromatics, volatile fatty acids (VFAs), sulfur compounds, and ammonia. Principal components analysis, characteristic molecular ratios, and ternary diagrams were used to differentiate the interactive influence of the odor sources. Among typical biotic compounds, terpenes were found to be more suitable as odor markers for their better fingerprinting character than sulfur compounds and VFAs. Ratios of p-cymene at sampling locations related to the biological treatment plant (aerobic status) were between 0.00 and 0.25, whereas those at landfill-related sampling points (anaerobic status) were between 0.25 and 1.0. The molecular ratio of terpenes was also found to be an appropriate means to differentiate between homologous and similar odor sources such as an aerobic biological treatment plant and anaerobic landfill.Implications: The aim of this work is to identify the key odorants comprising emissions from different zones in two adjacent waste treatment facilities, identify their precise sources, and distinguish the interactive influences between them. The emission of gaseous pollutants greatly affects the living quality of nearby residents, and odor complaints are becoming a major problem. In this study we utilized various pretreatment and analytical methods to obtain integrated emission information of gaseous pollutants. The results showed terpenes were found to be more suitable as odor markers for their better fingerprinting character than sulfur compounds and VFAs.
