About us

 La Charte VaLoo

The VaLoo Charter is a declaration that the members of VaLoo shall devote their energies to resource-oriented sanitation systems in Switzerland and commit to the shared values set out here.

L’assainissement circulaire

L’assainissement circulaire va au-delà du traitement des excréments humains et des eaux usées en permettant de fermer les cycles de matières entre les lieux de vie et  la production et consommation de denrées alimentaires. Les techniques utilisées pour l’assainissement circulaire visent à minimiser l’utilisation de ressources pour le traitement des excréments humains et à protéger l’environnement et la santé publique. Ces techniques permettent également de récupérer l’eau, l’énergie, les nutriments et les matières organiques après traitement.

Vision

L’assainissement circulaire fait partie intégrante de l’économie circulaire Suisse.

Mission

Notre objectif est de promouvoir l’assainissement circulaire en Suisse en connectant différents acteurs , en informant la population et en contribuant à créer des conditions environnantes appropriées.

Pour atteindre notre mission, nous sommes :

  • une communauté dans laquelle nos membres échangent des informations et collaborent pour atteindre des objectifs communs. Nous mettons à disposition un forum pour celles et ceux qui souhaiteant partager ou développer de nouvelles idées, qui mettent en œuvre des techniques et des systèmes de gestion pour la récupération des ressources, qui utilisent les ressources récupérées et qui consomment les biens produits à partir des ressources récupérées.
  • une source de connaissances crédibles concernant les technologies, les services et les pratiques à adopter. Nous transmettons ces connaissances au travers de groupes de travail, de tables rondes, d’ateliers et de campagnes de sensibilisation.
  • un représentant légitime de l’assainissement circulaire pour les dirigeants politiques, les agences gouvernementales et les praticiens.

Valeurs

Communauté

En tant que communauté, nous encourageons la collaboration et la co-création de solutions, la diversité et le respect mutuel dans le but de développer des solutions spécifiques aux différents contextes pour répondre aux défis régionaux et mondiaux.

Intégrité

Nous sommes conscients de l’énorme potentiel de l’assainissement circulaire dans la protection de l’environnement. Cependant, le développement et l’implémentation de solutions prend du temps. Afin de renforcer la confiance dans les nouvelles technologies, nous nous efforçons d’expliquer concrètement les opportunités et limites de nos procédés.

Sobriété

Nous renforçons l’économie circulaire locale et régionale afin de minimiser la consommation de ressources, la production de déchets, les émissions de gaz à effet de serre dans l’atmosphère et les pertes d’énergie.

Écologie

Conscients des ressources limitées de notre planète, nous nous engageons à réduire l’impact des activités humaines en protégeant, restaurant et rendant durable notre utilisation des ressources naturelles.

Working groups

Le co-développement est une des forces de VaLoo. Ensemble, nous poursuivons notre objectif commun qu’est la promotion de l'assainissement circulaire à-travers différents groupes de travail. Tous nos membres sont invités à participer aux groupes de travail et à apporter leur expertise et leurs idées. Actuellement, les groupes de travail suivants existent.

VaLoo Working Group

Board of directors

VaLoo existe sous la forme juridique d'une association. Notre comité se compose actuellement de huit membres qui se présentent ici.

Kayla Coppens

Project manager at Aneco and PhD student at the University of Geneva

«I produce the fertilizer I need to grow my own vegetables. I would love to live in a world where everyone can do the same!»

When Kayla became active in a housing cooperative in Geneva, her learning curve about wastewater problems and sustainable solutions to overcome them was steep. Kayla did her master’s project on a worm filter for wastewater treatment of for the housing cooperative Equilibre (2017) and became a founding member of aneco (2020). Aneco is an association dedicated to recovering the resources present in our wastewater through decentralized and sustainable treatment. Kayla played a key role in organizing VaLoo’s first General Assembly and is excited about the momentum generated by the co-creative power of its members. She strongly believes in VaLoo’s mission to enable innovative and sustainable solutions for circular sanitation systems in Switzerland.

Bastian Etter

Co-founder of Vuna

«The sanitation revolution will be slow, but permanent!»

When he was a kid building cabins in the forest, he always wanted to build the toilets first. Later, in 2015, after several years at Eawag, he founded Vuna, which builds circular sanitation systems in Switzerland and beyond. Vuna has licensed Aurin, the world’s first fertilizer made from urine. Bastian finds it exciting to be one of 44 people in the industry who founded VaLoo. As sanitation systems grow, VaLoo gives some structure and visibility to this diverse group of players. Bastian wants to strengthen the network between professionals, the construction industry, the authorities, in the different language regions of Switzerland and across borders.

Philippe Reymond

Independent consultant, member of Swiss Disaster Relief (SHA), working for UNHCR

«Even small-scale sanitation requires big visions.»

At the end of his studies, Philippe was given the opportunity to do a piece of work on urban sanitation planning in a city in Togo. There was no sewerage network there. The passion for decentralized sanitation has not left him, from the development context to humanitarian aid. The different realities were striking: institutional barriers, the level of commitment of the authorities, and the reality of a city where hundreds of micro-treatment plants stand side by side. For Philippe, it’s clear: governance matters! He sees VaLoo as a bunch of enthusiastic and committed people ready to take circular wastewater management to a new level.

Vincent Carel

Co-founder at piss&love

«I want to understand social taboos and make the toilet a cool topic!»

As a student, Vincent landed in the field of sustainable sanitation through an internship at the architecture firm atba and the housing cooperative Equilibre. He was curious to learn more about circular sanitation systems, a marginalized field but full of positive aspects (environmental, economic, and social). Vincent transported tons of urine, excrement and dry toilets throughout western Switzerland, which led to some unusual encounters. He wants to understand the psychological barriers associated with the topic in order to break social taboos and make the toilet a cool topic!

Jonas Linder

Co-founder Kompotoi AG

«My vision is to be able to reuse the resources from the toilet as nutrients after treatment, and that we all find that normal!»

In 2010, Jonas helped plant over 100 trees in a permaculture project, which were fertilized with the best compost from the toilet. That day, he decided to commit to contributing to putting those nutrients back into the loop. Kompotoi has built more than 700 mobile composting toilets, which operate year-round or during the summer. Ever since he started Kompotoi in 2012, he has been thinking about forming an association with other organizations. Now Jonas is more than happy that we could found such a broad-based association.

Dorothee Spuhler

Contact person for international cooperation and decentralized systems, Eastern Switzerland University of Applied Sciences

«I want to help VaLoo become a nationwide network, without forgetting any stakeholder.»

When she heard about pollution and forest dieback in elementary school, she started inventing a machine that sucks in bad air, compresses it and releases good air. Later, wastewater treatment and circular economy became her favorite topics of her work, her dissertation at Eawag and her involvement as a member of the Sustainable Sanitation Alliance (SuSaNa) core group since 2010. Today, direct air capture is a commercial technology available worldwide. Dorothee herself is still working on concepts to reduce wastewater and close nutrient cycles. Dorothee wants to support VaLoo in becoming a nationwide network, without forgetting any stakeholder.

Kai M. Udert

Titular Professor, ETH Zurich; Group Leader, Eawag

«With my involvement in VaLoo, I would like to help make the idea of resource recovery in the bowl socially acceptable.»

When Kai agreed to do a dissertation on urine source separation a good 25 years ago, the idea was completely new and surprising to him. During his work on “separation at the source”, he was able to work with very motivated and committed people, whether in research or practice. Particularly important to him are the Vuna project, which gave rise to the spinoff company of the same name, and the Blue Diversion Autarky project, in which teams were able to realize the ideas of wastewater separation and resource recovery for a toilet block. Kai believes that VaLoo provides us with a platform to discuss ideas and build foundations to implement sustainable concepts. With his involvement in VaLoo, Kai wants to help making the idea of resource recovery in the bowl socially acceptable.

Andri Heidler

Advocacy
«VaLoo is about collectively influencing social development in order to guide it in a sustainable and ecological direction!»

Andri Heidler is responsible for politics at VaLoo. He studied geography and agronomy, because for him a deep understanding of the relationship between humans and the environment is the key to a sustainable future. This is demonstrated particularly when it comes to food. The scientific, political and social discourse on local food systems is limited to food and ignores the local production of agricultural inputs such as fertilisers. VaLoo is the missing building block on the way to local and sustainable food systems.
