Republic Act 9003, signed into law on January 26, 2001, provides a comprehensive framework for solid waste management in the Philippines, emphasizing public health and environmental protection through systematic and ecological practices. Local governments are primarily responsible for implementation, which includes mandatory waste segregation, establishment of material recovery facilities, and control over waste disposal practices. The act also outlines regulatory measures, prohibited acts, and penalties for violations, while requiring periodic updates and the creation of long-term waste management plans.
