Abstract | This study is carried out to assess the present solid waste management and improve option in transportation system through introduction of new transfer stations in the Kathmandu Valley. Basic data, like the per capita solid waste generation rate in the study area have been determined based on a household level survey. An analysis of plastic wastes in different stages of waste management has been carried out with the help of a mathematical method (input management model) based on the law of conservation of mass. Linear programming applied for the optimization of the existing transportation system after the introduction of new (proposed) transfer stations in the waste management system. The model has been applied to determine the minimum transportation cost of solid wastes from 16 waste collection zones to alternative transfer stations and eventually to disposal site. The solution of the linear programming model has given an optimum amount of waste to be allocated from each collection zone to each transfer station with minimum transportation cost from collection zones to disposal sites through transfer stations. It is concluded that two transfer stations TS3 and TS5 are required to handle the waste to be collected and transported to disposal site Gokarna (D1) in 1993. In 1995, one more transfer station (TS4) should come into operation for the waste in 1995. Later, in 2000 and in 2005, the transporting capacity of transfer stations TS3 and TS4 should be increased to handle the wastes of that time. Further, recommendations are made for the construction of the transfer stations by SWMRMC. For the improvement of collection and transportation and the solid waste management as a whole, continuous public awareness raising activities and enforcement of rules and regulations are suggested. |
