(Micro)plastics regulation can address different stages along the life cycle of a plastic product including plastic production and product design, trade and consumer behaviour, recycling and waste management (so-called “landbased policies”), as well as wastewater management and water and marine protection (“water-based policies”). This session looks at the potential for water policies vs. land-based policies to tackle microplastic pollution from the local to the global level. The chair facilitates an interdisciplinary discussion among the panelists as well as between panel and audience. The discussion is supposed to shed light on the crucial target points for future (micro)plastics regulation.
