Working groups

Co-creation is a driving force at VaLoo. For this reason, we are advancing our common cause, scaling Circular Sanitation, with working groups. All members are welcome to participate in the working groups and contribute their expertise and ideas on how we should move forward. Currently, the following working groups exist:

The Advocacy Working Group is dedicated to initiating an enabling legal environment for Circular Sanitation in Switzerland. To do so, they already took part in the consultation of the partial revision of the USG. Philippe Reymond and Andri Heidler are the leaders of this group. Send us an e-mail to participate and learn more about further activities.

Knowledge & Awareness

In this working group members collect, create and curate knowledge on Circular Sanitation for the Swiss context. One of their outputs so far has been the infographic. The group is coordinated by Dorothee Spuhler and Gina Marti. If you want to participate or have further questions, please contact us.

International Collaboration

Circular Sanitation is also full of potential beyond borders. In order to benefit from international synergies and advancing our mission at the international level, the working group International Collaboration was created, which is managed by Michel Riechmann. Send us an email to help strengthen international synergies.


To make Circular Sanitation more tangible, VaLoo is planning a mobile exhibition, stopping at various locations in Switzerland! If you want to support the leaders Jojo Casanova-Linder and Lukas Baumgartner in this import mission, we are looking forward to hearing from you.
