Plastic pollution is a global problem that requires a comprehensive approach to address all stages of the plastic life cycle. It has reached alarming levels worldwide, with millions of tonnes of plastic entering the oceans each year. The Philippines is one of the top countries contributing to plastic leakage, with low-value plastics dominating the waste stream. The country lacks the capacity to recycle high-value plastics, resulting in low recycling rates (Jambeck et al., 2015; WWF, 2020b). To combat this issue, the World Wide Fund for Nature Philippines (WWF) has identified Extended Producer Responsibility (EPR) as a critical policy tool to reduce plastic consumption and leakage to the environment. EPR holds manufacturers accountable for the end-of- life impacts of their products and encourages eco- design in the business sector. Especially for plastic packaging, EPR can be a tool that accelerates the transition from linear to circular business models. To determine if the intended outcomes of EPR are met, the key elements of successful EPR programs can be used as a basis. These include mandatory participation, scope definition, equal treatment of producers and importers, involvement of waste management operators, and government support. While EPR has been institutionalized in the Philippines, there is a need for further guidance for producers, including micro, small, and medium enterprises (MSMEs) who may be obliged under the EPR Act. To address this, WWF has partnered with Philippine Learning Center for Environment and Social Sustainability of the University of the Philippines to conduct a case study as part of a working paper on EPR programs to inform stakeholders about the benefits, challenges, and opportunities of implementing an EPR with Producer Responsibility Organizations (PROs). As EPR programs grow from planning to execution, this working paper will be updated with learnings and insights. The present case study highlights the EPR activities of a PRO, a buyback and collection program, and a co-processing facility. The interviewed organizations in this case study all highlighted the importance of partnering with local government units to increase support of households and waste pickers in the proper segregation and collection of plastic wastes. Intensifying information and education campaigns, both for businesses affected by EPR and the general public, are recommended to improve the effectiveness of EPR programs.
