A Diagnostic Study of Household Solid Waste Management in Kollo, Niger

Abstract

Household solid waste management is one of the most prevalent problems in urban areas. This study aims to diagnose the household solid waste management system in the Kollo urban district of Niger. Specifically, the purpose of this study is to identify household waste types, determine their management methods at the household level, and estimate how much waste is produced daily. A survey of 200 households was conducted as part of the study. As a result of the study, four types of household waste, namely sand, organic matter, plastics, and others, were identified. At the scale of an urban municipality, waste production is estimated to be 9.44 tons per day or 0.72 kg per inhabitant per day. Additionally, only 47% of households have garbage cans for storing waste. Most households use trash cans with a capacity of 0.015 m³, with 27.5% evacuating waste daily, 50% twice a week, and 22.5% once weekly. 35 % of households dispose of waste in wild dumps, 30% dig pits to bury waste, 15% burn it openly, 15% use the waste to fertilize their fields, and 5% make other uses. The municipality provides no waste management service. The organization lacks the financial and technical resources to accomplish its goals. Kollo’s urban municipality, however, must develop strategies for managing waste sustainably and environmentally.
