El objetivo del estudio fue determinar la generación del metano como Gas de Efecto Invernadero en un RESA y un TCA. Para ello, se evaluaron las condiciones de operación, se caracterizaron los RSU confinados en temporadas de lluvias y estiaje y se determinó la generación de metano puntual y difusa. Con el fin de mejorar la operación del RESA bajo estudio, se detectaron ocho áreas de oportunidad y se documentaron los problemas ambientales del TCA. Si bien, el tipo de operación y la cantidad de materia biodegradable en los RSU (50.36% en RESA y 58.49% en TCA) influencian directamente la generación de metano por tonelada de RSU, en el TCA se incrementa en temporada de lluvias, mientras que en los pozos de venteo del RESA fue 15% más alto en temporada de estiaje, a causa de la recirculación de lixiviados durante la misma. Las emisiones superficiales de metano en el TCA fueron 97% más bajas que en el RESA, debido a su posible dispersión en los alrededores, lo cual es un riesgo potencial que requiere atención inmediata de las autoridades.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract In Mexico, 74% of the Municipal Solid Waste (MSW) produced are disposed in Landfills, however the operating conditions reported of the landfills as well as the open dumps sites are scarce the open dumps sites (ODS). The objective of this study was to determine the methane generation as Greenhouse gas in a Landfill and in an ODS. The operating conditions of the disposal sites were evaluated, the MSW disposed were characterized in wet (rainy) and dry (Dec-May) seasons, and the methane generation in venting wells and the surface emissions were determinated. In order to improve the disposal conditions of the study site operations, eight opportunity areas were detected and environmental problems of the ODS were documented. Even though, the type of sites operation and the amount of biodegradable matter in the MSW (50.36% in Landfill and 58.49% in ODS) influence directly the methane generation per ton of MSW, in ODS is increased during the wet season, while venting wells Landfill was 15% higher in the dry season due to leachate recirculation. The surface methane emissions in the ODS were 97% lower than in the Landfill, due to a possible spread trough the pores of soil which is a potential risk that requires immediate attention from the authorities.]]></p></abstract>
