Municipal solid waste management is a crucial issue in the decarbonization of urban contexts. The transportation of waste in the waste management system has significant environmental impacts that need to be considered when assessing the overall environmental burden.
The management of municipal solid waste is a crucial issue to address as we move toward the decarbonization of urban contexts. Not by chance, this sector plays a relevant role in the Covenant of Mayors program, whereby municipalities are called to design their own Sustainable Energy Action Plans (SECAPs). However, despite new regulations strongly pushing the recycling and reuse of materials contained in municipal waste, many cities still use large landfills. As part of the overall environmental pressure exerted by these urban systems, the transport of waste from collection points to landfills or treatment facilities must be considered in order to correctly assess the full environmental burden of waste management. To this aim, in this paper, the Ecological Footprint method is applied to the municipal solid waste management system of the city of Palermo (Sicily). The results show that the impacts produced by the means of transport used, both in the status quo and in the assumed enhanced scenario (with less municipal waste disposed to landfills in favor of recycling), are significant compared to those caused by the other segments of the waste management system. The concept of a saved footprint is also introduced here, in order to properly compare the two scenarios.
