Optimal Location and Proximity Distance of Municipal Solid Waste Collection Bin Using GIS: a Case Study of Coimbatore City

A better Municipal Solid Waste (MSW) management plans are required for developing urban cities in India. Further to facilitate MSW management, the enhanced options are to be provided for initial functions of MSW such as collection and transportation. The environmental and cost effectiveness of the functions would be achieved and analysed with adopting scientific technology like Geographical Information System (GIS). Hence, in this study GIS was used for investigating adequate number and positions of existing collection bins in one of the urban ward Sidhapudur, Coimbatore, India. The proposed numbers of collection bins were assessed according to MSW generation in the ward. Then the optimal positions were found with reference to existing bin locations, road network and population density. Moreover, based on the public preferable walking distance to drop the MSW to the collection bin, a model was developed. In this model, the three different proximity distances such as 50m, 75m and 100m around existing and proposed bins were generated and found the optimal distance. As a result, the entire area was covered by 75m distance around the collection bin with 99%. Thus, the proposed model suggested some modifications in existing system and which would recommend best possible collection services.
