In October 2023, it was time for the "Plastic Pirates" team of the Ecologic Institute to leave their desks and embark on a quest to find plastic waste. In autumn weather, the "Eco" Plastic Pirates explored the river Havel in Berlin-Spandau and made some interesting discoveries. Among their findings were 502 cigarette butts, 120 bottle caps, and 45 plastic bags.

In her presentation, titled "Evaluating environmental policies with citizen science data? An example from the Plastic Pirates investigating plastic pollution of rivers", Linda Mederake (Ecologic Institute) presented an approach to evaluate the Single-Use Plastics Directive with the help of citizen science data.

Plastic Pirates – Go Europe! is a joint citizen science campaign by the German Federal Ministry of Education and Research (BMBF) in collaboration with the Portuguese Ministry of Science, Technology and Higher Education and the Slovenian Ministry of Education, Science and Sport. The campaign is taking place in all three countries from 2020 to 2021 as part of the trio presidency of the EU Council. The goals of the campaign are to strengthen scientific collaboration in Europe, promote the level of dedication among citizen scientists and to raise awareness and consciousness for the environment. Ecologic Institute develops and programs the website in four languages. In addition to general information and instructions on the action, the website also offers an ordering system for the action materials of the participating countries.
