This research project explored whether strengthening the concept of extended product responsibility in international law has the potential of noticeably improving waste management in the Global South. The concept of Extended Producer Responsibility (EPR) aimed at taking into account waste management issues during the entire life cycle of a product (cradle-to-grave approach). Its main purpose was to reduce the costs of waste management for local authorities and taxpayers, while at the same time providing incentives for producers to design their products so that they are easier to recycle and dispose of in an environmentally sound manner, generating less waste overall.
