In Situ Characterization of Municipal Solid Waste Using Membrane Interface Probe (MIP) and Hydraulic Profiling Tool (HPT) in an Active and Closed Landfill

Municipal solid waste (MSW) landfills near a metropolitan area are renewable energy resources to produce heat and methane that can generate electricity. However, it is difficult use those sources productively because disposed MSW in spatially temporally heterogeneous. Regarding the prediction of sources, analysis situ properties an alternative way reduce uncertainty understand complex processes undergoing landfill effectively. A hydraulic profiling tool (HPT) membrane interface probe (MIP) test measures continuous profile with depth, including pressure, temperature, electrical conductivity (EC), relative concentration at field. In this study, we conducted series tests investigate characteristics active closed landfills. MIP results showed existed closer right below top cover several peak concentrations different layers landfill. As depth age increased, pressure increased for both The average EC decreased age. properties, obtained from sites could be used estimate help designing recovery systems.
