In the page's words:

We are united by the desire for a waste-free environment.
In the summer of 2020, our first member laid the foundation for our current volunteer project, which more members joined over time. Our mission is to organize waste collection campaigns in Hanover and to raise awareness about the current waste problem on our streets and green spaces.

If you are also motivated to volunteer for a litter-free city of Hanover, then why not come along to our regular litter collection events?
We organize large, communal CleanUps at different locations, to which everyone is cordially invited.
For each CleanUp event, we provide you with our equipment such as tongs, landing nets, gloves, collection buckets and bin liners.

Every little step counts and together we can achieve more. We look forward to welcoming you to the next CleanUp.
