Abstract
Solid waste management system is a tedious task that is facing both developing and developed countries. Site Suitability analysis and route optimization for solid waste disposal can make waste management cheap and can be used for sustainable development. However, if the disposal site(s) is/are not sited and handle properly, it can cause environmental pollution and affect public health, hence the application of GIS and Remote Sensing to waste disposal Site Suitability analysis and route optimization for solid waste in Yola town. Different factors or criteria were considered in relation to solid waste disposal sites. In order to achieve the aim of this paper, the Boolean logic was used, where suitable areas were assigned value 1 and unsuitable area were assigned 0 for each of the criteria. The Boolean images were overlaid to produce the suitability map. The result of the suitability analysis gave a total of six sites out of which three met the criteria of size having an area of 612.75Ha which constitute 6.12% of the total area of the study area. The optimized route were generated connecting the proposed disposal site which are truck 1, truck 2, and truck 3 with distances of 19.65km, 17.16km and 22.11km respectively. It is recommended that remote sensing and GIS can be used in increasing efficiency of solid waste management in an urban settlement.Keywords: Solid waste, Suitable site, Route Optimization, GIS, Remote Sensing and Disposal site
Highlights
Solid Waste Management is considered as one of the serious environmental problem facing both developed and developing countries like Nigeria
The Waste Management in Yola Town has been facing problems starting from the collection to the final disposal site due to the increased in waste generation, unplanned facilities, increase in population and poor management of waste bins
It has been attested that Geographic Information System (GIS) is a powerful tool for route optimization for solid waste collection and disposal was carried out
Summary
Solid Waste Management is considered as one of the serious environmental problem facing both developed and developing countries like Nigeria. The rapid growth of urban, agricultural and industrial activities due to population explosion has led to the generation of huge amounts of solid and liquid waste that pollute the environment and destroy natural resources (UNEP, 2005). The open dumping system is currently practiced which causes environmental degradation and public health problems to the populace in the study area. These resulted from non-adherence to the various criteria for suitable site selection. Solid waste management includes transportation; optimizing the process of managing waste is an issue that needs to be considered, in road routing for the Waste collection and transportation
