Abstract

This paper presents results on the decay of the emission of biogas in Londrina’s landfill (Limoeiro) after one year of closure and a comparison with the predictions of three mathematical models. Measurements were performed on the surface layer by static closed chamber tests and also in vertical drains. The total methane emissions were 9,602,192 Nm3/year and the total biogas were 21,117,824 Nm3/year. Compared with the latest measures before closing the landfill, there was a reduction of 38% of biogas after one year. The values predicted by the mathematical models were 55%, 69% and 57% higher than the measured value for the triangular pattern, Scholl Canyon and Software Landgem 3.02, respectively.
