The document is a study on Tehran's waste management problems and solutions conducted by students at Sharif University of Technology. It finds that Tehran produces over 8,000 tons of municipal solid waste daily, but waste collection and disposal are still challenges. Key issues include mixed waste collection, use of outdated methods, lack of workers, landfill leachate contamination of groundwater, and health impacts on local residents. Recommended solutions involve relocating landfills, improving isolation to prevent groundwater infiltration, using alternative disposal methods like incineration and composting, and separating dry and wet wastes.

Tehran & Pollutions
City 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.

Terminology And Definitions
Municipal 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.
5
Leachate 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.

Waste 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 Iran
Problems with poorly designed landfills
1.generation of liquid leachate
2.Production of greenhouse gases
3.Attraction of vermins, garbage scattering, etc

Waste 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.

Waste Collection Problems
Tehran produces more than 8,000 Tons of municipal waste each day.
collection of this mass of waste is still a serious challenge for the
municipality.
•Mixed Wastes are collected
•Old Collection Methods are used
•Lack of workers

Waste Collection Solutions
•Collecting several types of waste
simultaneously
•Mechanized Waste Collection
•Kerbside Collection
•Using Shooting system in
Apartments
•Fining Offenders

Waste Disposal Problems
Wastes 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

What should be done?
•Relocating landfill
•Isolating landfill to prevent
infiltrating
•Using alternative methods instead of
burying waste such as
•Incineration
•Recycling
• fermentation
•Converting To Compost
•Separating dry and wet wastes

Summary
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.
