HolyShit aims to educate citizens about the value of their pee and poop. The food that we eat and digest contains valuable nutrients which are essential in agriculture: phosphorus and nitrogen. HolyShit conveys this message in a playful card game. Furthermore, HolyShit develops public dry toilets in order to collect and compost citizens’ digested food and the valuable nutrients it contains. Let’s put the poop back into the loop!

HolyShit is currently turning into a start-up that realizes sustainable sanitation solutions for municipalities. Its objective is to raise awareness about the benefits and value of recycling human feces to close global nutrient cycles locally. By providing accessible public dry toilets and a playful communication tool, HolyShit educates humans about the value of and role of poop within the global cycles.
It began with a card game, developed during a Master’s thesis in the context of the research project zirkulierBAR, which is supported by the German Ministry for Education and Research. The game explains the differences between water-based, chemical and dry toilets and the advantages of sustainable sanitation solutions. It was used as a tool to convince and educate government officials, politicians as well as research institutions, funding programs and citizens about the benefits of recycling poop, in order to save water, energy and recover valuable nutrients.
Currently HolyShit is developing public dry toilets in a co-creative process with the city and citizens of Cologne. In order to compost the collected material, HolyShit is being consulted by the champion in the field: Finizio Future Sanitation. Finizio is running Germany's only facility for composting human feces. The recycled humus fertilizer is currently not allowed to be used in agriculture. Therefore, the research project zirkulierBAR together with ten partner organizations including Finizio are woking on scientifically proving the hygienic safety and effectiveness of the recycled fertilizer in order to change the German federal fertilizer regulations to legalize the compost.
HolyShit supports this effort by designing public dry toilets and transferring this innovative treatment process and a composting plant to the metropolitan area, the City of Cologne. This process shall provide data and serve as a blueprint for other municipalities to follow and implement sustainable sanitation solutions.
Sustainable sanitation solution for municipalities
HolyShit card game as educational tool for various contexts (schools, administration, politics ...)
Accessible Public Dry Toilets
Circular material / ressource flow
Locally closing the global phosphorus and nitrogen cycle
The key objective of HolyShit is to educate and raise awareness for the role that we humans play in global natural nutrient cycles. By collecting and composting human excreta individuals can see first-hand how "waste" can be transformed into a valuable resource for growing food and replenishing soil. HolyShit on the one hand is a pedagogical simulation card game which conveys the idea of sustainable sanitation solutions in a playful way. On the other hand it is a start-up in the making which lets citizens experience the process of closing global loops by going to the loo.
The global loops refer to the phosphorus and nitrogen cycle. Phosphorus is a finite resource that faces depletion in the next 50 to 300 years, making recycling necessary. The EU relies solely on imports for its supply, which emphasizes the need for local recycling. Furthermore 2% of the world's fossil energy consumption is used to create nitrogen fertilizer for agriculture. Recycling human feces to produce fertilizer for agriculture reduces the need for synthetic fertilizers and thereby the amount of carbon emissions. Furthermore traditional waste water treatment uses large amounts of water: 1/3 of daily water consumption goes towards flushing toilets. The use of dry toilets helps saving water and protects water bodies from nutrient overload and pollutants which can otherwise leads to algae blooms, the extinction of species and a loss of biodiversity. "Bringing the poop back into the loop" therefore promotes a greater understanding of the interconnectedness of humans and the environment.
HolyShit thereby tackles the following SDGs:
• 2 zero Hunger
• 6 clean water and sanitation
• 11 sustainable cities and communities
• 12 responsible consumption and production
• 13 climate action
• 14 life below water
• 15 life on land
Most people are unaware of the value of their excreta. HolyShit offers an opportunity to break the taboo and actually talk about the sensitive topic of using a toilet. The playful design of the card game enables people regardless of their age or status to talk about a topic we usually avoid talking about.
Furthermore the current development process of the public dry toilet is unique as it is happening in a co-creative user-centered design process with both the city administration as well as citizens. Thereby, the citizens ownership for the toilet is thereby strengthened. Additionally, the implementation of public dry toilets transforms the abstract concept of a circular economy into a local, tangible and practical experience. Using a well designed public toilet thereby becomes a pleasant, informative experience.
Designing for the public means designing for all members of society. When it comes to public toilets noBODY will be excluded. HolyShit separates urine and feces, not gender, age, religion, ability or sexuality. The public dry toilets will therefore be free of charge and accessible taking the respective norms into account covering aspects such as entry and exit, door width, clearances, floor space, fixtures, contrast and control elements. Furthermore the toilets promote gender equality.
Given the limited availability of public flush toilets (13) and mobile chemical toilets (37) in the city of Cologne, which has a population of over one million, the implementation of sustainable public dry toilets and a composting plant will enhance the experience of using public urban and green spaces. HolyShit unleashes citizens from the so called "urinary leash", which limits their mobility and restricts them to a small, familiar area due to the need to find a nearby restroom. People with continence issues, elderly, pregnant women, toddlers, homeless individuals, and those with urgent bathroom needs will benefit from public dry toilets.
Furthermore, involving citizens in the design- and decision-making processes of where to place the public dry toilets, empowers them and makes them feel valued, fostering a sense of community, ownership and responsibility. Engaging citizens in this process helps raise awareness and understanding of the importance of the global nutrient cycles, leading to greater public education and civic engagement. One small poop for wo*man, one giant leap for mankind.
This initiative engages different stakeholders at various levels from local to regional to national.
The local partners of this project are besides citizens, various departments of the city of Cologne including:
- Office for Climate Change Mitigation
- Waste Management
- Office for urban green areas
- Office for public participation
These offices are the ones involved in the co-creation process that is happening at the moment to design the first prototype of a HolyShit public dry toilet and the respective service and composting system.
Another local parter for the composting plant would be :metabolon, a research institute run by the University of Applied Sciences Cologne. It is the ideal place as it offers space, infrastructure and laboratories to compost and evaluate the collected material. A partnership is currently being discussed.
The generated data from a composting plant in Cologne shall contribute to the research project zirkulierBAR, which is a trans-regional project aiming to change the German federal fertilizer regulation in order to bring the poop back into the loop legally. The zirkulierBAR consortium includes partners like TU Berlin, the Center for Responsible Research and Innovation of Fraunhofer IAO, Leibniz-Institut für Gemüse- und Zierpflanzenbau (IGZ) e.V., Deutsches Biomasseforschungszentrum gemeinnützige GmbH, Hochschule für nachhaltige Entwicklung (HNE) and Eberswalde and Finizio Future Sanitation among others. All these institutions are working towards legal approval for recycling composts from human feces and also urine. HolyShit supports this effort by transferring this innovative technology to the city of Cologne.
The HolyShit initiative and previous Master's thesis "A Toilet Paper - Sustainable Sanitation Solutions for Municipalities" brought together multiple disciplines such as administration, biotechnology, chemistry, simulation game design and communication design. By interviewing stakeholders from these fields, who are part of the zirkulierBAR research project, a comprehensive understanding of the complex topic was gained. The HolyShit card game, as a result, synthesizes all the insights gathered from the broad research including the biochemical processes, nutrient cycles and composting processes, into an educational tool that is easy to comprehend. It leads to improved science communication that can now be used in various settings, such as schools or (in)formal learning contexts as well as co-creative workshops with government representatives to implement sustainable sanitation solutions in municipalities.
Further areas of expertise that are relevant for the next phase of HolyShit are participatory public design, product design, manufacturing, logistics, business modeling, financing and marketing. All these fields now come together in the ongoing design process to kick-start and found the HolyShit GmbH.
In contrast to other dry toilet providers in Germany HolyShit's goal is to fully recycle the contents from public dry toilets instead of incinerating the valuable material, in order to complete the circular process. By being consulted by the Finizio Future Sanitation, the champion in the field, HolyShit develops a blueprint for transferring this innovative treatment process to other municipalities. Going through this process allows for making mistakes that other municipalities can learn from and avoid.
HolyShit furthermore engages the users in a participatory urban design process for public dry toilets. This is unique within the public toilet field and increases the feeling of ownership, trust, empowerment and awareness for both the citizens and city administrators.
The implementation of a public dry toilet concept as well as the establishment of a composting facility can be transferred to other municipalities in Germany and beyond. Ranging from organizational to financial and logistic structures, HolyShit aims to develop a blueprint to be used by other cities and municipalities. The organizational blueprint includes the network of stakeholders that need to be involved as well as a viable financial model for municipalities.
The whole initiative is based on the service design approach. The current process is structured in the following phases:
Research: We gather information on the current situation, needs, and expectations of the city and citizens regarding public dry toilets. This includes conducting interviews, workshops and field research to understand public toilet users behaviors as well as the city's needs.
Ideation: Based on the research we develop ideas and concepts for the public dry toilets. This involves ideation, prototyping and testing in order to develop a user-centered solution for Cologne including all relevant stakeholders in the process (City administration various departments, AWB, :metabolon, citizens).
Design: We are developing and manufacturing a prototype of a public dry toilet and service system, taking into account factors such as accessibility, gender equality, user comfort, and sustainability (design for recycling). The design will also consider factors such as the location, size, and layout and maintenance of the toilets as well as the design of the composting plant. In order to meet the citizens needs, public participation is taken into account by building on existing results of former participatory processes regarding public toilets in Cologne and involving the public in a new process (online and offline).
Testing: The prototype will be tested in a public space in order to receive feedback and make necessary changes.
Evaluation: The following evaluation will analyze the performance of the public dry toilet to identify areas for improvement and iteration. This involves gathering feedback from users, measuring usage and satisfaction over time.
Implementation: After testing and evaluation the concept HolyShit will apply for the city's call for tenders for public dry toilets. By collaborating with manufacturers and the local waste management (AWB), HolyShit will be scaling and making sustainable sanitation accessible in Cologne.
HolyShit addresses the following global challenges summarized in the SDGs:
• 2 zero Hunger
• 6 clean water and sanitation
• 11 sustainable cities and communities
• 12 responsible consumption and production
• 13 climate action
• 14 life below water
• 15 life on land
The local solution of designing and providing public dry toilets and establishing a composting plant enables local nutrient recycling from human feces to close global nutrient cycles. The advantages of this project are:
- Saving water
- Protecting water bodies from nutrients and pollutants and therefore protecting biodiversity
- Soil protection and climate adaptation through organic humus production
- Saving energy and emissions in the production and recycling of nutrients
- Replacing energy-intensive synthetic fertilizers with recycling fertilizer
- Improved recycling through separate collection of materials (pee and poop)
- Cost reduction in sewage sludge treatment for phosphorus-recovery according to the German regulation AbfKlärVab2029
The progress can be categorized into two parts: Firstly, the development, application and publication of the educational tool and card game HolyShit. It served as a tool to establish a network of partners and organizations to realize a sanitary transformation within the city of Cologne. This work was awarded with the Cologne Design Award in November 2022 by the deputy mayor of Cologne Dr. Ralph Elster (CDU).
The second part refers to the process of implementation of the solution. The office for climate change mitigation is now funding a first public dry toilet prototype. Furthermore the local waste management association (AWB) as well as the municipal project "un:box Cologne" currently examine possibilities for implementing a composting plant. The costs for establishing this plant require significant amounts of investment funding for infrastructure including hygenization, a cleaning station for containers, a turnover machine for composting among other hardware.
Next steps regarding the founding of the HolyShit GmbH are the approval for the registration of trademark rights, business modeling, fundraising, user-research, prototyping, co-creation, public participation, testing of the prototype and evaluation, iteration, further product development and marketing. Once the first prototype is set up in July 2023, a city wide communication campaign shall contribute to spread the knowledge of sustainable sanction solutions in Cologne and educate local communities. A NEB social media campaign would be of great support.
The timeline is to finish the first prototype by July 2023. Establishing the composting plant is planned for the following month. The goal is to found the start-up mid to end of 2023 in order to be ready to apply for public tender for public toilets in 2024. The financial support of the NEB-prize would contribute to the realization of a public dry toilet start-up in Cologne in order realize a sustainable sanitary transformation.
