Knowledge, Attitude and Practices on Solid Waste Management Among Residents of a Riverside Barangay: Basis for Sustainable Policies and Programs

This study examined the knowledge, attitudes, and practices (KAP) on solid waste management (SWM) among residents of Barangay Consolacion and determined their relationship with the effectiveness of community waste management initiatives. Using a descriptive-correlational research design, the study was conducted from the fourth week of October 2024 to the fourth week of February 2025. A total of 350 adult residents aged 18–59 years were selected from a population of 2,800 through simple random sampling using Slovin’s formula. Data were collected through a modified and validated bilingual questionnaire utilizing a 4-point Likert scale. Descriptive statistics, including mean and standard deviation, were used to assess KAP levels, while Pearson correlation analysis determined the relationships among variables.

Findings revealed that residents demonstrated moderate knowledge regarding environmental issues (3.32), awareness activities (3.27), and SWM training participation. Respondents also showed generally positive attitudes toward community volunteers (3.29), garbage segregation (3.17), labeling of waste materials, and information sharing related to SWM. However, actual practices were only sometimes consistent, particularly in waste collection procedures (3.28) and regular waste control measures (3.14). The continued encouragement of open burning of waste outside the home (2.90) was identified as a concerning practice due to its harmful environmental and health effects. Statistical analysis revealed significant positive relationships (p < .000) between residents’ knowledge, attitudes, practices, and the effectiveness of the barangay’s SWM system.

The study was limited to one riverside barangay and relied on self-reported responses, which may affect the generalizability and accuracy of the findings. The study recommends strengthening mandatory waste segregation policies, enforcing bans on open burning, expanding environmental education campaigns, improving waste collection systems, and promoting recycling, composting, and community participation to support sustainable waste management and environmental protection.
