Abstract
Circular economy is viewed as the most promising path to a more sustainable use of plastic. It aims at reducing the consumption of resources by keeping materials within the value chain for longer periods compared to traditional linear material flow. Apart from reducing the consumption of plastics, plastic pollution (including microplastic contamination) is considered a major environmental risk. However, explicit considerations of microplastic contamination are seldom considered in studies on the transition to a circular plastic economy. In this perspective we provide reflections on why this is important, give examples of areas where recycling can lead to increased microplastic contamination and provide recommendations on how reduction of microplastic contamination and transition to circular economy can interconnected in future research.
