While conventional flushing toilets produce wastewater discharged to the sewer, dry toilets do not use water for flushing and produce solid compost. Because reusing human waste comes with risks, we have conducted research on the quality of these fertilizers on different parameters, such as metals, pathogens and medicine residues, and which treatment steps and production methods can be applied to best harvest the nutritional value.
*NB The Café and the Crossboat do have standard flush toilets installed
