Abstract :

Uncontrolled urban developments on one hand and changes in the pattern of consumption on the other hand has faced human kind with unexpected environmental pollution and undoubtedly waste production is amongst the very significant sources of environmental pollution which is created by human kind. Therefore, modern solid waste management is necessary to overcome the created problem. Such management should carefully consider various aspects of waste generation, storage, collection, transport, recycle and final disposal. Among these, one should admit that the higher cost of waste management belongs to transport of wastes. This includes both collections from residential areas, their transportation to transfer stations and finally transport to the landfill. In the present investigation, municipality No.22 of Tehran city is selected to examine cost of transport using WAGS software. The results show that the highest percentages of total transport cost is allocated to the wages of personal (almost 74%). The other components such as vehicles, repairs, full and others have a share of 16, 6, 3 and 1% of the total cost of collection and transporting of solid wastes. The overall expenditures of waste collection are about 44140 million Rails which indicates the need for additional investment equal to 36470 million Rails to the year 2020. At present the cost of collection and transportation of wastes to the transfer station is about 75 Rials/Kg. This amount encompasses all personal, vehicles, fuel and other associated costs. It is estimated that above mentioned cost increase from 75 to 81 Rials/Kg in the year 2020. At present each family has to pay 85640 Rials/year as a cost of collection.
