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

"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!"
