Landfillgas (LFG) management is one of the most important tasks for landfill operationand closure because of its impact in potential global warming. The aim of thiswork is to present a case history evaluating an LFG capture and treatmentsystem for the present landfill facility in Cordoba, Argentina. The results maybe relevant for many developing countries around the world where landfill gasis not being properly managed. The LFG generation is evaluated by modeling gas productionapplying the zero order model, Landfill Gas Generation Model (LandGEM - EPA),Scholl Canyon model and triangular model. Variability in waste properties,weather and landfill management conditions are analyzed in order to evaluatethe feasibility of implementing different treatment systems. The results showthe advantages of capturing and treating LFG in order to reduce the emissionsof gases responsible for global warming and to determine the revenue rateneeded for the project?s financial requirements. This particular project reducesby half the emission of equivalent tons of CO2 compared with thesituation where there is no gas treatment. In addition, the study highlightsthe need for a change in the electricity prices if it is to be economicallyfeasible to implement the project in the current Argentine electricity market.
