Study on Planning and Design of Transfer Station for Municipal Solid Waste Management in Khulna City of Bangladesh

Abstract

The present scenario of municipal solid waste (MSW) management in Khulna City is not satisfactory and poses a great threat to human health and nature. The Secondary Disposal Site (SDS) is causing much nuisance to both traffic flows and neighborhood, and deteriorating city environment. Realizing the present situation of MSW management. it is evident that there is a strong need to change the present secondary disposal system. These problems can be solved by removing these disposal sites with a well designed Transfer Station (TS) Networks. This study highligts the adaptation of transer station m ethodologies, sitti , planing and design of transfer station (TS) in Khulna City Corporation (KCC). The study enlightens the planning of TS considering sitting guidelines, location of TS, buffer zones and design of TS .From the study 18 TS location points have been identified on the basis of one km buffer zone and eight numbers of location points fbr TS have been found out on the basis of two km bufThr zone. I'he location points are summarized as Mirerdanga, Maniktala, Moheshwar pasha, Daulatpur, Khalishpur. Alamnagar, Mongla Port Area, Mujgunni, Rayermahal, Choto Boyra, Nirala, Shibbari Mor, Tootpara. Labonchara, Deana, Boyra. Sonadanga and Rupsha. Again, on the basis of two km radial distance, KCC map has been subdivided into eight influence areas showing eight location points which are Mirerdanga, Shahipara, Daulatpur, Khalishpur, Choto I3oyra, Sheikhpara. Tootpara and Labonchora. Total population of KCC areas 11,74,648 having generated waste of 406 tonnes/day and wastes to be deposited in TS be 370 tonnes/day. From the study, three types of TS have been designed (TS with ramp. TS with conveyor belt and TS with hydraulic lift having covered or uncovered facilities) considering minimum land area, estimated waste to be hauled at TS. types of vehicles used in TS, mechanisms used in TS. size, capacity and availability of primary and secondary collection vehicle, capacity of demountable containers, hours of operation. sufficient space for movement of truck, and other facilities involved in the facilities of TS. The involvement of private sectors from home and abroad and city authorities can evaluate this study to come forward by solving this issue with sustainable technology and Finance. In this context, Bangladesh can get the advantages by bringing foreign investment to convert the SDS into sustainable TS setup successfully based on the socio-econoniic settings and technological capabilities.
