“Microhabitats powered by Shit” or “Poop Loop” envisions a future where self-sufficient closed-loop microhabitats are created to maximize resource usage and maintain cyclic flows of nutrients. Inspired by space travel where resources are scarce and utilized to the fullest, the project aims to study natural closed loop systems and implement a small-scale closed loop prototype. The main technology proposed for this project is based on Patent 360US6077548A (Organic waste processing and it’s uses thereof.), An organic waste processing method that transforms organic refuse into nutrient-rich biomass and other byproducts. The success of this proof of concept will pave the way for its potential integration into future closed loop systems. Furthermore, the project explores the analysis of human waste, particularly poop, to gather valuable information about human health, habits, and societal conditions. This data analysis, utilizing Patent 555US7490287B2 (Time series data analysis), offers insights into population growth, mental health trends, and nutritional patterns over time, aiding in making informed decisions for the closed loop systems. The sponsor of the project, Studio Carbon, is an award-winning design studio that emphasizes technology, systems thinking, and storytelling to create resilient solutions for a better future. The project is undertaken in collaboration with the Space Business Innovation Centre Noordwijk (SBIC) as part of their startup support for space technology ventures. The project’s objectives include understanding waste management systems, proposing adapted space technologies for waste processing and analysis, and creating a functional prototype or proof of concept of the product. The deliverables consist of a 3D CAD model of the product, and documentation of design decisions. By successfully developing and integrating these technologies, the project aims to establish closed loop systems for nutrient flows in communities, including off-grid and nomadic living environments for immediate implementation and a more pervasive and widespread adoption in the future.
