Citizen science on Marine Litter: Combining Research and Action!

Since 2018 HZ Green Office is organizing clean-up events at the beaches, canals, forests, and harbors in Vlissingen, in collaboration with the Municipality of Vlissingen and “Doe Mee, Verlos de Zee!”. Together with Rijkwaterstaat, also integrated monitoring is carried out of the marine litter distribution on the coasts of the Eastern and Western Scheldt. In this way, we participate in scientific research and at the same time contribute to efforts to keep our local beaches clean.
With our clean-ups we contribute to the following Sustainable Development Goals (SDGs):

In 2019 we monitored marine litter on five beach locations in Zeeland and tested different monitoring methods. The outcome of this research in 2019 can be read in this report: USING CITIZEN SCIENCE IN MONITORING PLASTIC DEBRIS ON BEACHES. Read the story that Janine Vink, student journalism from Utrecht University, wrote about one of these cleaning and monitoring events.  

One year later, we are building upon this research; in collaboration with Delta management and Rijkswaterstaat, the 5 locations that were studied in 2019, are again monitored during the World Cleanup Day on 19 Sep 2020.  

Join us!

Everyone is welcome to join us! Students can link the cleanups to HZ Personality/ free credits

Clean-ups and monitoring sessions are taking place on a weekly basis. To always be up to date about the weekly clean-ups, visit the HZ Green Office Instagram or the HZ Green Office Facebook page.

You don’t need to bring anything to participate, but dress up warm enough! The clean-ups, together with other Green Office activities, are a chance to gain HZ Personality (or FCC) credits (double hours) while connecting with students from other study programmes, participate in an outdoor activity, and making a step towards a clean and circular economy. 

-> Interested? Just let us know upfront via Instagram or by sending an email to or 

This initiative is based on volunteers, so also non-student volunteers are welcome to join our efforts! 

You can also just do your own cleanup. Good locations where lots of waste can be found are around the canal between Middelburg and Vlissingen, De Buitenhaven in Vlissingen, around HZ Middelburg in the park, and around Supermarkets. Or just select a location in your neighborhood you like to make clean and look nice!

If you link this to HZ Personality, make some pictures as proof of your activity. But before that, do not forget to talk with your study coach and have the PDP approved. For having the hours signed, contact us at our HZ email.

If you want to borrow a "prikker" from us, let us know via or or contact your local municipality.
