Normalizing novel sanitation practices in transitioning towards circular food and energy systems

ABSTRACT Wastewater from sanitation contains several scarce resources that can be reused for purposes of energy and food production. Sanitation infrastructures, however, are often overlooked in debates on circular food systems, while the role of sanitation could be pivotal in combatting resource depletion facing agriculture. Transitioning sanitation infrastructures to support circular systems also needs a thorough understanding of the sanitation practices involved, as resource-oriented sanitation systems require a de-routinization in how we make use of toilets and deal with wastewater. Instead, novel sanitation practices are needed for circular developments around sanitation to ensure the reuse potential of wastewater. This research paper focuses on exploring how sanitation practices are shaped and embedded in wider configurations of domestic practices and its implications for the routinization of novel sanitation practices. A mixed-method research design has been adopted studying sanitation practices and infrastructures in three distinct neighborhoods within the Amsterdam Metropolitan Region. First, a survey was conducted that enabled the development of a neighborhood typology. Second, in-depth interviews were conducted to uncover the embeddedness of sanitation practices. Results highlight the importance of normalizing novel sanitation practices when linking sanitation to food systems and list five steppingstones that may help doing so.
