title: The PAF model: an integrated approach for landfill sustainability.
abstract: Lab-scale tests were set up to investigate different options for achieving sustainability by reducing long-term landfill emissions. The options which have been studied and compared with the traditional anaerobic landfill for unprocessed refuse were: mechanical-biological pretreatment, landfill aeration with forced and with natural advective air flow (semi-aerobic), flushing. Combination of different options have been experimented. The combination of mechanical-biological Pretreatment, Aeration by the semi-aerobic method and Flushing (PAF model) seems to synergize the advantages of the individual options. The research is ongoing and further studies are necessary in order to assess the full-scale applicability of the model.
