EMISIONES GASEOSAS DE UN RELLENO SANITARIO EN MÉXICO. COMPARACIÓN CON LOS MODELOS DE GENERACIÓN DE BIOGÁS

Abstract

In order to estimate the generation of biogás in a landfill, there are some mathematical models (Modelo Mexicano v.2.0, Modelo de Primer Orden TNO, Modelo de Primer Orden Multi-fase, Modelo EPER Francés, SWANA Orden Cero, SWANA Primer Orden Simple, SWANA Primer Orden Modificado, SWANA Primer Orden Multi-fase, LandGEM v3.02 y Scholl Canyon). In this work, these model have been compared for the sanitary landfill HASAR’S, located in Zapopan (Jalisco, México). Furthermore, the results of the models have been compared with the real data measured in the landfill from 2009 to 2011. Compared to the real values, the models TNO, SWANA firts order (simple and modified) and LandGEM overestimate the generation of biogas. The models Afvalzorg multiphase and Scholl Canyon, however, underestimate. The models SWANA first order and LandGEM are very far as the real measurement, therefore its use must be rule out for this landfill. The “Modelo Mexicano de Biogás”, the french EPER and SWANA order zero are the most approximate. The relative errors of the results proveded by each model with respect to measure the real generation has been calculated too.
