Solid waste management (SWM) models implemented in municipalities in the Mediterranean and Aegean regions of Turkey, while responding to the waste management needs of cities, also pose a burden on the Mediterranean environment. In this study, the analysis of the environmental burden arising from urban solid waste management and the requirements to reduce this burden were investigated, focusing on the city of Izmir, on an Aegean Sea coast. Within the scope of the study, environmental burden was analyzed by landfill gas impact modeling and life cycle assessment (LCA). In the LCA process implemented, the processes of transportation, collection, transfer to the transfer station, landfilling in the sanitary landfill and energy generation from the gas generated during the management of urban solid waste are included in the system boundaries. EPA LandGem Model was used for the evaluation of the landfill gas and SimaPro 8.5.0 software was used for the LCA study.
