Help us develop super fancy, green, dry public toilets for town centres!


The project




Are you as frustrated as we are to flush 10 litres of drinkable water every time you pee?


Dry toilets are already found at festivals, isolated sites and even some households, so we decided to make them for the city centre. We need you to make this shit happen!


Water problems concern all of us, particularly when we live in the driest region of France. Flushing the toilet uses 1/5th of our water consumption. Dry toilets are a real alternative to all of these problems.    





The high quality dry toilets that we have developed are a step forward in the world of public toilets. Completely automatic, our cabin is comfortable to use, with no bad odours, and no need for sawdust.


We’re going to clean the cabins several times a day by bicycle and the anti-bacteria hand gel will keep this cabin particularly hygienic. Our cabin is adapted for disabled people and can cope with high demand, especially thanks to the outside urinals. We want to bring a state-of-the-art public toilet to our city that renews our urban space in an ecological sound way.  





With the first prototype now installed and working at the Montpellier zoo, we are proud show the public the cabin that we have developed over the past two years






During this two month test period, the collected urine will be used as a fertilizer on a small area of arable land in the IRSTEA compound. This research institute, Ecosec's partner and a specialist in agricultural waste-water re-use, will help us with the development of several sanitary and agronomic tests.


We are setting up a network of subsurface drip irrigation to fertilize ornamental and vegetable plants at a depth of 20cm to demonstrate the fertilizing potential of urine and their power to accelerate the breakdown of waste into compost.




Today, we’d like today to appeal to your generosity in order to shift up a gear in our project. We need to establish a proper workshop, with decent tools and adapted machines.


To do that, we need you. Thank you so much for your support!






Symbolic of an ecological way to treat our most basic waste, these toilets will demonstrate to users that water savings can be made without losing comfort, and to educate people on the importance of composting and recycling.




Nutrients and organic matter from human waste pollute our waterways. However, they can be very beneficial for soils and plants when re-used hygienically. Waste from Ecosec toilets will be managed in a hygienic, ecological and local process. Local re-use is at the center of our approach.


There are many pragmatic and hygienic ways that we could re-use urine in our city centers. From fertilising grass along the tramlines, the football stadium, and in the many parks, urine re-use could be useful, easy and local. Some producers of spirulina are also interested in obtaining urine in large quantities.



The Ecosec cooperative organisation has been developed by local partners. In order to strengthen our commitment to society, Ecosec is dedicated to being an equal opportunities employer, and is committed to employing disabled workers and the long-term unemployed.

The creative commons spirit is accompanying us for the applied researchs, the designs and technology. Ecosec believes in open source and would like to work with the FabLab of Montpellier to build an e-cabin fully connected.






We are four young idealists from Montpellier, Benjamin, Bernard, Vincent and Nicolas, all excited to re-invent our city! With complementary skills, we’re keen to develop new cabins, water-saving products, compost management services, and other complementary products.


Benjamin: A civil engineer specializing in on-site sanitation and father of two children. After working on several continents on ecological sanitation, he developed a great desire to apply these concepts to his home country. The dream was to participate in an ecological transition in the heart of his city, within a cooperative structure, and so the Ecosec project was born.


Bernard: A former technician in monitoring systems and father of three children. A conservationist, he has always wanted to work on these issues within his adoptive city. “Greening” a city sounds complicated, each of us can work towards it in our own way at a local level, large or small.


Vincent: A water-science engineer specializing in the nitrogen cycle. Vincent’s work is dedicated to applied research on urine management. He understands fully the problems of water scarcity and pollution, and to him, the development of dry toilets will play a huge role in the sustainable management of our water resources and fertilizers.


Nicolas: A young business school graduate and passionate about the concept of Social Solidarity Economy. Nicolas is in charge of establishing strong links with local communities to better respond to their problems in public health and organic waste management.


Please help us to continue this adventure!





We’d like to thank all our partners without whom it would have been impossible to make it this far.



Why fund it?

We started this project a year ago, and have invested a lot in our first cabin prototype and designs, and today we ask you to help us take this to the next step.


Our prototype and designs have generated a lot of interest and we believe that we have reached the stage where we need to invest in a proper workshop, in order to fulfill existing and future orders. We also need to invest in an electric bicycle and a compact aerated composter, as well as compulsory regulatory checks, commercial flyers and a video.


Being supported by a community is very important to us, crowd funding is therefore the way to finance ourselves while maintaining our values. We are only at the beginning of this adventure, and it will be thanks to you that we will be able to prove that urban ecology does not mean going back to the stone age!





If we achieve our initial goal of raising €11,000, we will to set ourselves a second goal of  €15,000 which would allow us to develop a series of automated tools to connect our e-cabins: a real-time indicator of the frequency of use, the quantity of collected urine, the temperature and humidity of the compost, cleaning shifts, and so on.

FAQ Questions about the project

+ Est ce que les urines sont dangereuses pour la santé ?

D’après l’Organisation Mondiale de la Santé (OMS), selon son rapport datant de 2012 :

Chez l’individu en bonne santé, l’urine contenue dans la vessie est stérile. Mais différents types de bactéries peuvent provenir du tractus urinaire. Elles ne sont normalement pas transmises à d’autres individus via l’environnement. Les agents pathogènes sexuellement transmissibles peuvent occasionnellement être excrétés dans l’urine, mais rien n’indique que leur survie potentielle en dehors de l’organisme puisse poser un problème de santé publique.

Certains agents pathogènes, comme Leptospira interrogans, Salmonella typhi, Salmonella paratyphi, Schistosoma haematobium et certains virus, sont excrétés dans l’urine. Une série d’autres agents ont pu être détectés dans l’urine, mais le risque de transmission environnementale peut être considéré comme insignifiant.

+ Et les matières fécales, qu'est que vous en faites ?

Jusqu'à ce que notre composteur situé sur la plate-forme de notre atelier soit validé par le Service des eaux, l'Agence régionale de la santé et les élus, nous avons un accord avec la station de traitement des eaux usées de Montpellier pour récupérer notre collecte.

Nous développons un système de co-compostage qui permet d'atteindre des températures élevées (jusqu'à 70 degrés) durant plusieurs jours et qui écarte ainsi tout risque sanitaire.

Le document le plus récent sur le compostage de résidu de toilettes sèches est le suivant :

+ Cette histoire de vélo, ça marche comment ?

Une personne de l'équipe sera en ville en vélo chaque jour, tout le monde y passe à égalité dans la coopérative. En 8h de tournée quotidienne, avec 5 cabines en place nous avons estimé qu'il les lavera 5 ou 6 fois chacune par jour. En plus de sensibiliser les utilisateurs, la maintenance des cabines sera optimale et leur taux de panne extrêmement réduit.

Nous comptons ensuite rentabiliser ces trajet en vélo en proposant de la gestion de compostage en pied d'immeuble. Avec un service quotidien de lavage des bio-sceaux et un gestion des bacs, nous pensons offrir aux habitants d'immeuble une solution urbaine facile pour les déchets organiques.

+ Le composite c'est pas très naturel ...

Effectivement, la résine que nous utilisons ne l'est pas. En revanche, la fibre à l'intérieure est de la toile de jute (origine angleterre) pour notre prototype et sera en fibre de Lin (Origine normandie) pour les suivantes.
Les résines bio-sourcées font leur apparition dans les laboratoires et nous sommes confiant de pouvoir commencer à les trouver chez un fournisseur français rapidement.

+ Y a t-il des exemples de valorisation d'urine à grande échelle ?

Et oui, de nombreux projets voient le jour ces dernières années pour valoriser au maximum cette ressource si précieuse.

Contenant la majorité des nutriments que nous rejetons, à savoir principalement l’azote, le phosphore et le potassium, elle est un précieux engrais si elle revenait au sol.

Les meilleurs exemples sont en Chine ces pommes et cerises fertilisées par 2000 étudiants et 30 professeurs :

Une collecte de l’urine de 175 personnes aux états unis :

Le projet VUNA en Afrique du Sud, conduit par l’institut suisse EAWAG :

L’envolée des prix des engrais nous obligera rapidement à valoriser cette ressource, il n'y a aucun doute la dessus.
