Abstract

Organic waste is particularly important as it influences the generation of leachate and gas in the landfill. This work aimed to monitor the process of biodegradation and methane gas generation in an experimental cell with urban solid waste in Brazil. Monitoring in the experimental cell was carried out for 1.100 days, using environmental measurement equipment and portable gas analyzers with measurements in the central vertical drain of the experimental cell. It was possible to monitor the methane gas generation curve and the composition of biogas during the solid waste biodegradation process. The results obtained from the research confirmed the explanation for the drop in the methane generation rate observed in several landfills after the completion of waste disposal.
