  Background and Purpose: In recent years, a variety of models have been used to evaluate the waste management systems in Tehran in order to select the best waste management options. But the problem of the final disposal of waste in Tehran is still one of the issues related to the environmental management of the metropolis. The purpose of this study is to provide one model for allocating optimal annual quantities of waste to waste management subsystems of Tehran in order to achieve the highest efficiency, reduce costs and increase system revenue.Materials and Methods: In this research, first by referring to the Arad Kooh complex in Tehran and interviewing with experts and using the information recorded in this complex, the required data was collected. Then, an optimal model proposed for allocating optimal annual amount of municipal waste with considering all of limitations to 5 sub-systems of recycling, aerobic compost, anaerobic digestion, incinerator , landfill using genetic algorithm improved by fuzzy logic with the aim of reducing the total cost of the municipal waste management system in the MATLAB environment and its results were analyzed.Findings: The significant results showed with increasing capacity the subsystems with lower cost and more profitability, the system will not necessarily seek to be optimized and optimal amount of waste allocated to each of the subsystems such as recycling, aerobic compost, anaerobic digestion, incinerator and landfill were estimated about 750,000, 960000, 182000, 325000, 780000 tons in each year, respectively.Discussion and Conclusion: According to the results of the optimal model proposed in this study, it is necessary to carefully follow the flow and optimal allocation of waste from the annual production of Tehran to each of the following subsystems: recycling, aerobic compost, anaerobic digestion, incinerator and landfill in order to achieve the high annual efficiency for municipal solid waste management system in Tehran city.

  In past times, Tehran citys solid waste management was included mostly collecting and burying waste. Environmental knowledge was increased over times due to improvement in environment technology and sciences and so the relationship between the public health and environment became more obvious. Main waste producer sections are trading centers such as hotels and restaurants which mostly produce semi-household wastes. According to studies undertaken on District 6 of Tehran city, hotels are the main waste producers. The most part of waste composition includes organic and regenerative matters with plant-and animal-based origin (70%). So solid waste management must concentrate mostly on such materials separations and compost production. Hotels solid waste management is a topic which yet no study has been implemented about it or if any, there is no publication in general and expertise libraries about the subject. The present study has been carried out since 1385 to 1386 aiming to investigate the current status of solid waste management dominated on Tehrans hotels. There are 72 hotels, 180 hostels and 160 restaurants in the city. Study areas include waste production rate, distinction of physical composition, Storage, collecting and transportation systems. To improve waste management task it is necessary to obtain required knowledge about these steps. Data gathering with respect to hotels solid waste management was performed through referral for sampling (random selection), physical analysis and questionnaire completion in which the later was carried out with 11 copies for hotels in District 6. The questionnaires have been standardized according to Delphi method. Among hotels with various ranking in service delivery quality, two hotels were selected randomly and considered for investigation, (in some cases with seemingly more changes, the number was increased to 4 hotels). Sampling of two hotels (Enghelab and Azadi) in the District was carried out with 3 referrals for Physical analysis and waste fractions weight was measured separately. Above mentioned trading units have been selected randomly for physical analysis and because of waste composition similarities in hotels (due to undertaken studies), a bin was selected randomly for every trading unit which then was analyzed physically. Step sampling method has been introduced for final conclusion. Based on the project findings, hotels’ waste production per capita is bout 1-1.5 kg. It was also observed that waste separation is not undertaken in 36.3 percent of hotels but 63.6 percent do the task mostly for dried bread. The study shows the average percent of waste physical composition in hotels is as following: 75.8% wet residual, 14.6% plastic, 1.5% metal cans, 2.5% paper, 3% glass and 2.5% other materials. It was also shown that 27 percent of hotels were not equipped with bin and 45 percent had 1.2 and 3 bins, 27 percent had more than 4 bins. Waste collecting procedure is carried out in un-mechanized collection system in 27.3 percent of hotels which 36.4 percent of them are satisfied with mechanical waste collection and 36.4 percent are very satisfied with the method Manuscript profile

  Abstract Background and Objective: Increasing production of waste in cities is an issue that municipalities deal with it and a significant amount of municipal funds spent on the collection, transport and disposal of the waste, in addition to the many environmental problems will follow. Method: This paper aims to identify social factors that influence the production of household waste is reduced. For this purpose, the two regions 3 and 10 of Tehran municipality in terms of per capita household waste generation and associated social factors were studied. Because these two regions close together despite the population, in terms of physical and social differences with each other, which can help reduce household waste produced per capita. Then to answer assumptions, based on a survey questionnaire containing open and closed questions was used. Findings: The findings show that many social factors have a direct impact on per capita production of household waste, such as age, gender, marital status, family size, length of stay in Tehran and region, type of home and respect for the separation of waste. Then the two regions based on criteria and indicators of physical, social, environmental and management were evaluated and by region 3, percentage points respectively is 67, 64, 36 and 38 and the region 10 is 47, 46, 33 and 36. Finally, 20 action plan to reduce domestic waste generation per capita was presented with an emphasis on social factors. Discussion and Conclusion: The results of the questionnaire were analyzed by using statistical tests. Manuscript profile

  Introduction: Increasing hazardous industrial waste and lack of necessary regulations for management of them have led to serious problems in some parts of Iran. The aim of this study was to evaluate the situation of collection, transportation, recycling, and disposal of hazardous industrial wastes in the Shams Abad Industrial Park of Tehran, Iran. Method: The research was descipttive, cross sectional one. The data was gathered by first referring to industrial units and completion of Iranian Environmental Organization Questionnaire and then analyzing the gathered data.Findings: In the Shams Abad Industrial Park, 532224 ton/year or 1478ton/day of different industrial waste is produced. The biggest proportion of waste includes mineral wastes which are about 426048 ton/year or 805%. The smallest proportion in Cellulose waste is produced at a rate of 30.36 ton/year or 0.005%. 90 percent of the active industries at this park produce solid industrial waste.Results and Discussion: The result of this study showed that disposal of these wastes is mainly done by recycling and re-usage in other industries is about 85%. The best , most economic, and most environment-friendly waste management activity of the Shams Abad Industrial  Park is prevention of production, increasing the potential recycling, and reuse of material with emphasis on sorting at the production site, increasing mechanical sorting, and decreasing production of disposable waste.                                                                                                                                                                                                            Manuscript profile

  Background and Objective: Increasing hazardous industrial waste and lack of necessary regulations for their management have led to serious problems in some parts of Iran. The aim of this study was to evaluate the situation of collection, transportation, recycling, and disposal of hazardous industrial wastes in Abbas Abad Industrial Park of Tehran, Iran. Method: This study was a descriptive cross-sectional study performed using questionnaires and local visit during 2013. Findings: In Abbas Abad Industrial Park, 60,000 ton/year or 165ton/day of different industrial waste is produced. The largest proportion of waste includes metal waste which is about 47,232 ton/year or 80%. The smallest proportion is textile waste which is produced at a rate of 34 ton/year or 1%. 90% of the active industries at the Park produce solid industrial waste. Conclusion: Disposal of these wastes is mainly done by selling to trading agencies in amount of about 55%. The wastes of most industrial units at this Park have the potential to be recycled and re-used in other industries in amount of about 33.2%. The best, most economic, and most environment-friendly waste management activity in Abbas Abad Industrial Park is prevention of production, increase in the potential of recycling, and reuse of material with emphasis on sorting at the production site, increase of mechanical sorting, and decrease in production of disposable waste.

  Waste is natural consequence of living human communities and environmental hazards caused by environmental mismanagement of solid waste, one of the fundamental problems. In the past decades, exponential growth of urban population in developing countries and speed of urbanization phenomenon, necessity of sustainable environmental development and efficient management of waste has been established. The main goal of the current study is applying various spatial analyses, with use of geographic information system in order to optimum site selection with minimal environmental adverse effects for urban waste burial. Therefore, in first step, effective data Layers in determining of landfill of Karaj ( like land use, streams, wetlands, roads,  morphology, ground waters, demography, wildlife parks, soil) from data bases and organization was prepared. The second step, data layers (digital maps) was entered to soft ware of Arc GIS9.2 and data base was created. In the third step, according to limitations, suitable areas, was extracted with using of GIS. Then these data was applied as appropriate options ( input data) for AHP. In the next step for determination priorities of the remaining landfill options according to criteria is used by AHP. The results of this study are evidence that GIS and AHP provide performance tools for selection and priority of optimal landfill. Also in this study land slope and ground water have more important than other criteria and option 3 is most appropriate for landfill. Manuscript profile
