Abstract

Disposal of solid waste is one of the means of managing the waste in our urban centers which requires huge amount of money and other resources such as time. Most agencies face the problem of limited resources for waste disposal and in most cases, evacuation of the waste at waste collection centers are not given equal priority by the agencies. In this study, Analytical Hierarchy Process (AHP) was applied to prioritize evacuation of solid waste in collection centers in Abuja Municipal Council (Federal Capital of Nigeria). Abuja has thirteen (13) waste collection centers and two (2) disposal sites. Three criteria were identified as being used during the waste evacuation exercise. These are Population Density (PD) areas, Very Important Personalities (VIP) areas and Road Network/Drainage Channel (RNDC) areas. A nine point scale of AHP was used to quantify the verbal judgments obtained from the Officers of the Solid Waste Management Agency in respect of the comparable importance of the criteria in relation to waste evacuation, and comparable importance of the waste collection centers in relation to each of the criteria. An excel spreadsheet program was developed and used to generate the synthesized matrices, consistency indices and priority weights. The results reveal that for waste evacuation in Abuja, Nigeria, Wuse 1 waste collection center should be given the highest priority while Wuye waste collection center should be given the least priority.
