What beautiful canals we have in Leiden! With 'De Grachtwacht' (translated: The Canalwatch) we are working on plastic-free canals and make people aware of the urban nature in and around the canal. With the Plastic Spotter canoe fleet, we organise weekly clean-ups and conduct real scientific research into plastic pollution. Not only do we clean the city, we also analyse where this waste comes from in order to turn off the tap. We exhibit our most exciting finds in the windows of the bridge keeper's house on the Marebrug in Leiden. Here, right above the canal, we coordinate the clean-up actions, welcome our volunteers and process the material from the clean-ups together. Our team is more than 500 volunteers strong! Subscribe to our newsletter and keep an eye on this website for more information about our exhibitions, research and other news.

The clean-ups, the research and our exhibitions are entirely dependent on funds and donations. Donate here to help us continue our work. Every donation is welcome. Enjoy the clean canals!
