From 12 to 14 November 2025, Hannah Brunkhorst took part in the Participatory Science Conference (PartWiss) in Leipzig, where innovative projects and approaches were presented under the motto "Researching together – Impulses from citizen science, participatory, and transdisciplinary research". At the end of the first day of the PartWiss 2025 conference, participants gathered for a large poster session. A total of 30 posters were presented, providing interesting insights into various projects in the fields of citizen science, participatory and transdisciplinary research.

In spring 2025, the Plastic Pirates were active on the Danube River once again. School classes and extracurricular youth groups were invited to collect their own data on plastic pollution and get to know the Danube better as an important habitat and transport route. The aim of the campaign was to raise young people's environmental awareness and give them a hands-on approach to scientific work. Participation was free of charge.

This spring, the German Plastic Pirates are once again setting off to explore plastic pollution in our waters. From 1 May to 30 June 2025, school classes and youth groups are invited to take part in the sampling period. The investigation will focus on the German coasts and the river systems of the Elbe and Danube, including their tributaries.
