June 2016, Rhine, Germany: On board Greenpeace ship Beluga II is a special device to take samples and test micro plastic during the tour on the rivers Rhine, Main and Danube. Micro plastic is hardly visible but nonetheless a huge problem. Plastic waste is ground to tiny particles in the sea via UV radiation and waves. And there is already plastic waste in our waste water that is too small to be filtered out. Microscopic microbeads are e.g. in toothpaste and peelings and often get into the sea via sewage systems.
