Status of Household Solid Waste Management and Associated Factors in a Slum Community in Kampala, Uganda

Abstract EN

Background.

Only a third of the total waste generated in slum communities in Kampala is collected and disposed of to the landfill every month.

This study assessed the status of household solid waste management and associated factors in a slum community in Kampala, Uganda.

Methods.

We conducted a community-based cross-sectional study involving 395 households using a semistructured questionnaire and an observational checklist.

Proper solid waste management was determined based on possession of waste collection and storage receptacle; collection receptacle ability to minimise nuisances (covered); segregation of waste; presence of flies and other vectors; and collection receptacle fill status.

Prevalence rate ratios and their 95% confidence intervals were used as a measure of association.

Results.

Only, 41.3% (163/395) of the households exhibited proper waste management practices.

The majority of the households 85.8% (339/395) owned solid waste storage receptacles, most of which were sacs 61.7% (209/339) and would minimise nuisances 72.9% (245/339).

The main type of waste collected was biodegradable materials 56.7% (224/395).

The majority of the households 78.7% (311/395) did not segregate their waste.

Solid waste was mainly transported to the collection point by pulling the collecting sac 54.4% (215/395).

The city authority 73.9% (292/395) and private companies 12.9% (51/395) were the major entities collecting waste.

Factors associated with proper waste management were collecting waste in plastic containers (adjusted PR = 1.27, 95% CI (1.04–1.55)), polythene bags (adjusted PR = 0.26, 95% CI (0.14–0.47)), and paper bags or metallic bins (adjusted PR = 0.13, 95% CI (0.03–0.44)) as well as awareness of solid waste management laws (adjusted PR = 1.49, 95% CI (1.20–1.85)) and the dangers of improper solid waste management (adjusted PR = 2.15, 95% CI (1.51–3.06)).

Conclusion.

Solid waste management was generally poor.

As such, a cascade of interventions that address knowledge, physical, and behavioural aspects of solid waste management is required to improve its management in slum communities.
