"13 years ago I took the initiative and started the cleanups in Maassluis.

After a while, many people joined me, and now the area is cleaner and people’s behavior is changing.

My wish is for Maassluis to become the cleanest area in the Netherlands!"


Become a Volunteer

Are you located in the Netherlands and want to contribute to cleaner cities and riverbeds? 

Would you like to help us in other ways? We are curious to know more about it! 


"Plastic doesn’t belong to the environment and we have to take action! I use plastic so I believe I have to do something about this problem.


I feel I need to act now and inspire people around me."
