Currently, sanitation is undergoing a multifaceted challenge. While most areas in the world are in urgent need of improved sanitation, other areas require think how to make their sanitation systems less environmentally stressing.
Technologies promoted in contexts absent of the rudimentaries of sanitation, such as UDDTs (Urine Diverting Dry Toilets), are designed to have a positive ecological impact – through the separation at source from urine and excreta – while providing an bonafide alternative to flush toilets in terms of affordability and usability. Through reverse innovation, these technologies could be introduced to contexts with improved sanitation, due to their additional benefits, fulfilling the need to rethink sanitation with a sustainably mindset.
One of the many benefits of the UDDTs is that it is contained in a tight loop system. There is an increasing need for decentralization of crucial societal services as that transition would result in decreasing risk (i.e. if one system fails less people are impacted). UDDTs decrease complexities of sanitation systems, minimizes risks by localizing them, and has an overall lower CO2eq and water requirement in comparison to other improved sanitation types.
Regardless of the context, challenges in establishing such low-tech solutions, are not merely technical, but rather of a social nature. As people are often unfamiliar with the concept, they may not know how to interact with the technology nor do they recognize its potential.
We aim to inspire students and professional with or without a passion for circular systems by developing a kiosk that processes human waste into homegrown Bloody Maries. By bringing the processes back to a human scale, we set out to demonstrate a thought-provoking way to take advantage of a valuable product that is currently flushed down the toilet. At the same time, we challenge the societal perception of human waste, by placing it in the absurd context of a cocktail party, provoke a discussion around how to reframe sustainability.
