  Nowadays, environmental hazards that originated from inappropriate management of waste are one of the main problems of the country. Therefore, the development of waste management system and new and advanced technologies entry is necessary. Waste disposal by incinerator is an effective method. Unlike landfill, the use of incineration does not require long-term care and there is the possibility of energy extraction. One of the main disadvantages of this method is emission of air pollutants from the stuck of incinerators and management of the residual wastes such as ash. Therefore, selecting the best place for construction of the municipal waste incineration power plant will increase its benefits, reduce costs and eliminate community dissatisfaction by identifying and considering the involved and effective factors such as environmental, economic and social factors. In this paper, literature reviewes, searching for valid universal guidelines and the related articles in databases were used to introduce and compare the criteria mentioned for locating the municipal waste incineration power plant as one of the most important steps in designing a comprehensive waste management system.

  Waste landfills change over time due to exposure to physical and biological factors, these changes include the production of leachate and its penetration into the subsoil, groundwater pollution, production and emission of gases from waste decomposition, and finally the settlement in the site. The leachate produced flows in different layers of waste and carries toxic and polluted substances to surface or groundwater. Kacha River, which carries the contamination load from Saravan landfill, flows into Siahrud River; Siahroud passes through this lands on its way, flows to the north and after joining Goharroud, enters the eastern part of Anzali Wetland. In this study, sampling stations were located in Saravan landfill and Kacha River and sampling was done in winter and summer and COD, BOD, TDS, pH, EC, ammonia, phosphate and nitrate parameters were measured. Comparison of the results of leachate analysis of Saravan landfill and Kacha River in summer and winter showed that all parameters, including BOD and COD parameters, which are indicators of contamination load in the Kacha River, increased in the drought season (summer) compared to the wet season (winter) Which indicates the amount of more pollution from Saravan landfill to Kacha River and from there to Gohar River and finally Anzali wetland.

  Nowadays management of discharged materials is considered as one of the factors influencing sustainable urban development plans and recycling waste materials is very important in the areas of environment and urban management, and source separation of waste itself is the main pillar of recycling.The purpose of this study is to identify and examine social factors and practical conditions for participation in source separation of waste. The study also is going to determine the roles of each factor and the ratio of their share portions. The methodology used for this research is cross-sectional surveying. The society of the research is composed of 15-75 years old Tehranian citizens. The statistical sample also includes 384 persons. Multi-stage clustered random sampling is used and data were collected by questionnaire. The general framework of the research model includes three groups of variables including social factors (social capital, socio-economic status, satisfaction of the municipality), practical conditions and economic benefits of source separation of waste. Results showed that trust in the Municipal Organizations, economic benefits of source separation of waste and practical conditions are associated with participation in source separation of waste. Multivariate regression analysis showed that 47% of the variance of participation at source separation of waste is explained by the model. Results showed that practical conditions have an important role in participation in source separation of waste in Tehran city. Manuscript profile

  Abstract Like many other human activities, the construction and operation of electric machines, in addition to its benefits, has a negative impact on the environment, especially pollution. According to these cases, it is possible to discuss about the moment of pollution, if the amount of pollution depends on the size of the device, which of the stages of the existence of the device has more pollution than the other stages (construction, operation and dismantling). And how to reduce the environmental impact. In the construction of electric machines, a series of materials are used to make the electrical system (winding), the magnetic system and also. Necessary materials for making the mechanical structure and car insulation. All these materials are the result of complex processes, energy consumption and more or less pollution. Once obtained, these materials are subjected to mechanical processing and produce various pollutants along with the resulting components. Manuscript profile
