This study is the first comprehensive scientific assessment and material flow analysis of plastic packaging waste in the Philippines. The evaluation framework of the report is built on a thorough analysis of the country’s waste reduction and management system, and recycling market for plastic waste. This serves as foundation for the proposed elements and components of an extended producer responsibility (EPR) scheme for the Philippines, including short- and medium- term actions that need to be taken to lay the foundations for EPR. EPR is an environmental policy approach that emerged in the 1990s and is now increasingly recognised around the world as a useful tool for accelerating the transition to sustainable waste management and a circular economy. It also encourages waste reduction and the development of more environmentally friendly packaging design. The basic approach of EPR is based on obliging businesses (i.e., manufacturers, importers, and sellers) to assume full responsibility for the products they offer to the public – not just during consumption but also during the end-of-life phase – or once their products have become waste. EPR works alongside and complements general waste management systems typically run by the government and its citizens.
