• Resumen

  • Landfills provide the most economical and generally accepted method in the World for the disposal of municipal solid wastes. However, the anaerobic degradation of organic matter based on the action of microorganisms in landfills leads to the emission of biogas, which has a great contribution to enhanced greenhouse gases. The estimation of biogas emissions requires comprehensive field measurements in landfill or the use of simulation models built under local climate conditions. One of the mathematical models used for evaluating the amount of biogas potential in landfills is the LandGEM model, which is applied in this research. The aim of this study is the estimation of biogas production in the Mulenvos landfill in order to assess the energy recovery potential and to reduce emissions into the atmosphere. The methane and carbon dioxide emissions were measured in situ. The results were compared with the emissions predicted using the first order decay model.
