Landfill costs have been estimated for an average case that represents a reference landfill model for Northern Italy. This case is based on the analysis of more than 15 landfill projects per the requirements of the Italian legislation. These projects were based on the suggestions of the national landfill guidelines and best practices. Costs have been analysed through the four phases of the landfill lifetime (i.e.: design and authorization, construction, operation, and aftercare) and expressed per unit of waste volume in order to define the "landfill gate fee" that represents a unit payment for the whole landfill life cycle service. The estimated value, equal to 86.04 €/m 3 , is in line with the analysed references and it is mainly attributed to the costs of leachate disposal, the staff, and raw materials for liner construction. However, other factors such as localization, climatic conditions, waste quality, landfill geometry, operative procedures, and financial and legal aspects can significantly influence the landfill gate fee. Finally, the results of this study, based on a large data analysis, represent a starting point for a comparative economic analysis to support political and technical decisions.
