Plastic pollution constitutes a serious threat to world’s oceans, affecting biodiversity, ecosystem services and livelihoods.  Curbing plastic pollution is not simply a matter of changing consumer and municipality waste patterns because pollution sources are often linked to technologies and decisions applied in the manufacturing stages of products entering the global supply chains. At the same time, remediating plastic pollution already dispersed throughout the oceans is infinitely more challenging, although efforts are succeeding in removing plastics from coastlines and neighboring waters. As some aspects of manufacturing-related plastics pollution can be dealt with by circular approaches and other strategies, this session brings together advocates, researchers, producers and donors to discuss research, industrial and behavioral initiatives aimed at dealing with this problem.
