Waste Management Waste products are unavoidable in any society and community is one of the main requirements. Hence, it is necessary to establish waste management systems. The solid waste management system, according to the amount and composition of waste, there are several ways in addition to the economic costs, the burden on the environment are different. A tool for assessing the environmental impact of waste management there are many different ways, but one of the most commonly used methods, Life Cycle Assessment (LCA) is. The life cycle impact assessment methods and different models exist for the evaluation and comparison of different options for managing waste can be used, And the best and most effective option to run, both environmentally and economically, was chosen. In the present study, this approach was used to investigate the status of Solid Waste Management Isfahan City. For this purpose, five scenarios include (1) collecting, separating and sorting (MFR), composting, landfill unsanitary storage (temporary RDF) (2) collecting, MFR, composting and anaerobic digestion, incineration plants, landfill sanitary and residual ash landfill (3) collecting, MFR, waste incineration plants, sanitary landfills and residual ash landfill with methane gas collecting and energy recovery (4) collecting, separation at source at 10% capacity, composting, sanitary landfill with methane gas collecting and energy recovery (5) collecting, MFR, direct burial in sanitary landfill with methane gas collecting and energy recovery. Required Data Life cycle inventory analysis from Resource assessment and research projects over the preparation and completion of the questionnaires were collected by field personnel and work. The life cycle inventory cataloging was done using the IWM-2 model. Then, the results The life cycle inventory cataloging the five categories of energy consumption, greenhouse gases, acid gases, smog and toxic effluent was assigned. Lists the values ??of the characteristic parameters and finally beat the ecological profile was obtained for each of the scenarios. Environmental and economic point of view, these results indicate that scenario (4) collecting, separation at source at 10% capacity, composting, sanitary landfill with methane gas collecting and energy recovery As appropriate management options, in addition to economic efficiency, reduce pollution and energy consumption plays an important role in waste management systems has caused. keywords : Environmental Life Cycle Assessment, Solid WasteManagement Isfahan City.
