Extended Producer Responsibility (EPR) is a potentially efficient and powerful measure to achieve a circular economy for plastics. EPR builds on the principle of polluter-pays, by shifting the responsibility for the treatment of waste upstream to the producer. Well-designed EPR schemes can reduce the burden on public budgets and incentivize effective end-of-life collection and treatment. In addition, EPR may provide producers with increased incentives to design durable and recyclable products, which in turn can contribute to reducing pollution. Countries that have implemented EPR policies have generally achieved higher collection and recycling rates than other countries. This study starts with an overview of the current organization and performance of EPR schemes for plastic packaging in Norway in Chapter 2, followed by details of the current legal framework for these EPR schemes in Chapter 3. Chapter 4 provides an overview of EPR schemes for plastic packaging in comparable countries to Norway, highlighting advantages and weaknesses of the different models. Chapter 5 assesses the efficiency of the current legal framework for EPR for plastic packaging and identifies the barriers that hinder the transition to a true circular economy. Necessary changes to the legal framework are described in Chapter 6, while other measures that could accelerate the creation of a true circular value chain for plastics and prevent plastic pollution are presented in Chapter 7.
