摘要：

Scope/Aim. Solid waste management in Ibadan Metropolis, the capital of Oyo State in Nigeria has been a serious concern to the government and the public for several years. The waste generated at the rate of about 0.51kg per capita per day from 11 Local Government Areas is transported to the existing four landfill sites and dumped indiscriminately. This study recorded various collection points using GPS, available collection bins, number of households using the facilities and identified the gap. Methods. The waste transportation routes used currently in respect of distance and travel time was assessed using a GIS analytical distribution and optimization mapping. Results. The results indicated that there is need for provision of 837 waste bins (5m3 capacities) to meet the demand gap. By following the optimized transportation routing, the waste management authorities can clear the waste 15 per cent more efficiently and save NGN 1.2 million (USD 3,335) on energy every year. Conclusions: The GIS analytical distribution and optimization mapping tool will help the city authorities in improving waste collection with significant saving in operational cost. It is replicable in other parts in African countries. © 2020 Widener University School of Civil Engineering. All rights reserved.
