Investigation of Domestic Solid Waste Collection and Management in Selected Residential Areas in Abuja Metropolis, Nigeria

Abstract

This study looked into home solid waste collection and management in specific residential districts in Abuja Metropolis, Nigeria. The goal was to measure waste generation patterns, evaluate collection efficiency, and compare household practices and satisfaction across various residential typologies. A cross-sectional survey design was used, with a structured questionnaire distributed to 420 households purposefully chosen from high-income (Asokoro), middle-income (Gwarinpa), and low-income (Kubwa) neighbourhoods. The results showed a hybrid collecting system dominated by private providers (31.2%), the governmental agency AEPB (26.0%), and informal collectors (25.2%). treatment quality and household satisfaction differed greatly, with high-income, gated estates obtaining more consistent treatment. Organic waste was the greatest component (40.2%), and while 62.3% of households separated waste, this was heavily influenced by residential type and service reliability. The study concludes that structural fragmentation and spatial inequalities, rather than household unwillingness, are the main constraints. It recommends a diversified service model, formal integration of the informal sector, and investment in organic waste diversion programs to improve the system's efficiency and equity.
