Abstract:
This study assessed the level of awareness, implementation, and effectiveness of Republic Act No. 9003, also known as the Ecological Solid Waste Management Act of 2000, among the residents of Barangay Catbangen, San Fernando City, La Union. Employing a mixed-method sequential explanatory design, utilizing quantitative surveys and qualitative semi-structured interviews to gather data across six key domains: waste segregation, composting and recycling, proper waste disposal, MRF, penalties for non-compliance, and impact on health. Quantitative results revealed a "High" level of awareness, while implementation and effectiveness were rated "Moderate". Statistical analysis demonstrated a significant positive relationship between awareness, implementation, and effectiveness, although high awareness did not always guarantee consistent implementation. Qualitative findings identified barriers such as weak monitoring, inconsistent waste management, irregular garbage collection, and inadequate infrastructure. The study recommends increasing barangay resources, improving collection services, and using digital infographics to strengthen environmental education and support effective waste management practices.
