Today, along with the industrial growth of societies, the population growth proce and changes in the quality of the wastes causes increased problem to cities . So the management of wastes and the interrelationships of elements in this system have been one of the most important issues in recent decades in huma community . Hence, deployment of the waste management system is essential. This can be done with environmental assessment tools such as life cycle assessment. using the life cycle assessment, a comprehensive look at the whole existing and applicable processes and the environmental impacts generated by them can be gained. In this research, the life cycle effects assessment method was used to study the environmental and economic impacts of various waste management options in Ardebil. For this purpose, after reviewing the current management method and waste disposal in Ardabil city, and considering the quantity and quality of waste produced, also considering the new methods of waste disposal, five scenarios were defined and modeled. These five scenarios include: (1) collecting waste, separating, composting, unhealthy burial (temporary storage) without collecting and extracting energy. (2) waste collection, separation, compost and anaerobic digestion, waste incineration plant, landfill residues and desiccation in the healthy landfill. (3) Waste collection, separation, garbage power plant, landfill of residues and desiccation in landfill, along with methane capture and energy recovery. (4) waste collection, separation at source with 6% increase in capacity, composting, burial i sanitary landfill, along with methane capture and energy recovery. (5) Waste collection, without separation at source, non-sanitary landfill without collecting and extracting energy. Then, the scenarios were modeled using the IWM-2 model to estimate environmental impacts and cost of scenarios. In the evaluation of effects stage, the logistic tensions of the cataloging stage were classified according to the effect classes defined in the MET method. In the last stage, the most appropriate scenario was identified in terms of environmental and economic characteristics. The results of this study showed that the fourth scenario, assuming that the total amount of waste entered in this scenario, about 20% was for separation and recycling, and about 65% was transferred to the compost plant, and the rest of the waste products from MRF stage And other waste products and residue from factory generated from MRF stage composte was transferred to the healthy landfill site. As the best management option, in addition to economical savings, it was ecologically selected, the fourth scenario has the highest recycling rates compared to the other scenarios defined in this study, which is an increase in recycling. It prevents the production of contaminants and also makes significant economic savings. Also, the fifth scenario, which shows the current waste management in Ardebil, is the most environmentally and economically disadvantaged scenario, the main cause of which is non-sanitary landfill generated without methane gas production, methane gas is one of the most important global warming gases In the fifth scenario, the highest amount of methane production was obtained from other scenarios of this study.
