MORPHOLOGICAL CHARACTERIZATION OF MSW LANDFILLS

Landfill characterisation has been carried out by analyses of waste sa mples collected from different depths in the municipal landfill of Tor ino. The main result has been that landfill drilling to collect sample s can provide useful information about landfill morphology: e.g., insi de a landfill, water lenses can form and their origin can strongly inf luence organic matter degradation rates and, therefore, biogas generat ion and composition. In addition, the investigation suggests that land fill behaviour and biogas production can be predicted in a more reliab le way if very simple chemico-physical analyses of collected samples a re performed.
