Abstract: The aim of this study was to review and assess the different municipal solid waste management (MSW) scenarios using a comparative life cycle assessment approach in Iran. For this purpose, the capital of Iran was selected and five different scenarios including: anaerobic digestion (AD, Sc-0), landfilling combined with composting (Sc-1), incineration (Sc-2), incineration combined with composting (Sc-3), and AD combined with incineration (Sc-4) were taken into consideration. The results obtained showed that the scenarios Sc-3 and Sc-1 led to the most adverse environmental impact in the Human Health and Ecosystem Quality damage categories. In the Climate Change damage category, the scenario Sc-1 resulted in the worst impact while the other scenarios showed improving impacts on this damage category. Also, the scenario Sc-1 had the least helpful effect on the Resources damage category. The overall analysis of different scenarios implied that the scenario Sc-1 was the worst scenario among the studied scenarios. The results also showed that the most eco-friendly scenario to be implemented in the future would be the combination of AD with incineration (Sc-4).
