Abstract

Biogas generation capacity from a sanitary landfill is investigated by two approaches with two first order models: practical approach with experimentally calculated parameters from laboratory biodigestors; a theoretical approach with defaults. Results showed that accumulated total between 2008 and 2148 reached 42,877 tons of biogas or 11,453 tons of methane, and 148,062 ton of biogas or 39,549 tons of methane, by the theoretical approach. Highest rate of biogas production would be the same in the two approaches by 2020. The model revealed that theoretically biogas production may be three times greater than practical results and the real period of higher generation rates would be shorter than forecasted when default parameters were employed. The above means that international data may not be applicable to the true situation of landfills in Brazil.
