Over 90% of waste is improperly disposed of, exacerbated by rapid urbanization, inadequate infrastructure, and gaps in public knowledge and perception regarding waste disposal risks. This study investigates the relationship between knowledge, perception, and infrastructure as determinants of waste management behavior. The study aims to assess the influence of knowledge, perception, and infrastructure on waste management practices in Montserrado County. A quantitative, cross-sectional design was used, surveying 383 households in Monrovia (20.78%) and Paynesville (79.22%). Quota sampling ensured representation across socioeconomic groups. Data were collected via structured questionnaires. The findings reveal that waste management knowledge and infrastructure have a significant relationship with and do influence residents’ waste management practices, while perception does not have a statistically significant impact. The combination of knowledge, perception, and infrastructure shows a strong predictive relationship with waste management practices. These results highlight the critical role of education and infrastructure availability in promoting effective waste management behaviors. Strengthening infrastructure is key to improving waste management Practices. Authorities should invest in waste collection points, recycling facilities, and regular waste disposal schedules to enhance community participation and environmental sustainability.enWaste management practicesEnvironmental health and sanitationCommunity knowledge and perceptionInfrastructure and public servicesSolid waste management—LiberiaThesis
