4Tehran & PollutionsCity of Tehran with approximate population of 12million people is producing daily amount of 8000 tons of solid waste Rapid growth of population and lack of services, has forced serious pollution problems to the city such as air pollutions, water pollutions and waste pollutions.Waste pollution refers to pollutions that is produced during the process of collection, transport and disposal of waste materials.

Sharif University of TechnologyElectrical Engineering Department Terminology And DefinitionsMunicipal Solid Waste (MSW) is a waste type that includes predominantly household waste (domestic waste) with sometimes the addition of commercial wastes collected by a municipality within a given area. They are in either solid or semisolid form and generally exclude industrial hazardous wastes.5Leachate is the liquid that drains or 'leaches' from a landfill and Contains High Organic contaminant concentrations and high ammoniacal nitrogens.

Waste management is the collection, transport, processing, recycling or disposal of waste materials. Sharif University of TechnologyElectrical Engineering Department Different types of solid waste

Sharif University of TechnologyElectrical Engineering Department 8Waste Disposal Methods (1)Landfill Disposing of waste in a landfill involves burying waste to dispose of it, and this remains a common practice in most countries including IranProblems with poorly designed landfills

1.generation of liquid leachate2.Production of greenhouse gases3.Attraction of vermins, garbage scattering, etc

Sharif University of TechnologyElectrical Engineering Department 9Waste Disposal Methods (2)Incineration Incineration is a disposal method that involves combustion of waste material. Incineration and other high temperature waste treatment systems are sometimes described as "thermal treatment". Incinerators convert waste materials into heat, gas, steam, and ash.

Mixed Wastes are collected Old Collection Methods are used Lack of workers

Sharif University of TechnologyElectrical Engineering Department 12Waste Disposal ProblemsWastes are being transferred by semi-trailers to the Kahrizak waste disposal site in South part of Tehran for more than 50 years. Industrial and hospital solid wastes are not separated and therefore organic and mineral contents of leachate are extremely increasing.Leachate are infiltrating to underground waters.Local residents are suffering from skin and respiratory diseases due to polluted environment.Land Consumption

Sharif University of TechnologyElectrical Engineering Department 13What should be done?Relocating landfillIsolating landfill to prevent infiltratingUsing alternative methods instead of burying waste such as Incineration Recycling fermentation Converting To CompostSeparating dry and wet wastes

Sharif University of TechnologyElectrical Engineering Department 14Summary The main objective of this project was to analyze the present status of solid waste management in Tehran, and subsequently, to draw up a policy regarding their generation, collection, on-site handling, storage, processing, recycling, transportation and safe disposal. Factors affecting the important management issues in the operation of Tehran's solid waste management system were discussed. design data and other useful information selected from a variety of reliable sources were presented. The practical aspects associated with solid waste management systems, such as Collection, Transport and disposal were discussed and suggestion were presented.
