Let’s mobilize and preserve lake waters together

If you want to take action to preserve the waters of Lake Geneva or the water point closest to you, here is how to collect waste. Whether for 10 minutes, 1 hour or an afternoon, alone or in a small group, take part in this collection and list your harvest on the website. In addition to our environmental impact, the data will allow the Association for the Safeguarding of Lake Geneva to carry out a study in 2022. A real participatory science! Are you free and interested? Here's how to participate in the collection:

What equipment do I need to collect waste?

It's very simple, firstly we recommend that you collect waste with gardening gloves, if you come across a sharp object or for greater comfort. Regarding collection bags:


  • For incinerables: various plastic packaging, cigarette butts, etc.

Bring one or more taxed bags, because in some municipalities it is forbidden to throw large quantities of waste into public trash cans. Our advice to make counting easier: separate the cigarette butts from the start.

  • For recyclable waste: PET, aluminum, glass, etc.

Bring one or more reusable bags, such as a tote bag or an Ikea bag, for recyclable waste. Our advice to make counting easier: have one bag per type of waste.


Our final advice: do your cleaning in pairs so that one person collects the waste and the other lists it as you go on You are free to swap roles along the way.

At the end of your collection, you can go to the nearest sorting point or to a recycling center.

Thank you in advance for your commitment!
