Evaluation of managed landfill system in the Province of Potenza (Southern Italy) was performed by jointly applying Geographical Information System (GIS) and Emergy Synthesis methods. A GIS survey of the whole Province was carried out in order to generate a large-scale picture of the waste management system.

The main product is identified in the provided service of safe disposal of urban solid waste, for which an emergy cost of 1.15E+09 seJ/g was calculated. A co-product landfill biogas was also considered, with a production cost of 1.11E+05 seJ/J. These results, together with other findings from the investigation, will serve as a reference case for a planned GIS-emergy evaluation of other small and large landfill sites in Southern Italy.

Abstract

Evaluation of managed landfill system in the Province of Potenza (Southern Italy) was performed by jointly applying Geographical Information System (GIS) and Emergy Synthesis methods. A GIS survey of the whole Province was carried out in order to generate a large-scale picture of the waste management system. According to the results of such a survey, the municipal landfill of the town Potenza was identified as the most relevant waste management site in the area and was therefore chosen as a case study. Data provided and structured by GIS were then converted to emergy flows and emergy-based indicators, in order to provide a comprehensive understanding of the demand for environmental support to the whole process. The main product is identified in the provided service of safe disposal of urban solid waste, for which an emergy cost of 1.15E+09 seJ/g was calculated. A co-product landfill biogas was also considered, with a production cost of 1.11E+05 seJ/J. These results, together with other findings from the investigation, will serve as a reference case for a planned GIS-emergy evaluation of other small and large landfill sites in Southern Italy.
