The City of Zurich is testing a new type of toilet technology at the Z\u00fcriWC site in parc Schindlergut: The Nutrient Harvester NH-25. Hidden in the service room of the solid stationary public toilet mostly visible as a large concrete block, at the heart of the system a new way of wastewater treatment and valorization is tested. The modular and compact Nutrient Harvester was specifically designed to largely reduce the volume (by 95%) and to convert urine into into safe, dry plant fertilizer \u2014 on-site, without a sewer connection and with a view towards a sustainable future.\u00a0The entire process runs fully automatically. Stabilization substrate needs to be refilled and the fertilizer concentrate removed only once a month.<\/p>\n
<\/p>\n
The technology was developed at the Swiss Institute for aquatic science and Technology Eawag and comercialized by its new spin-off ogmo.\u00a0The pilot test is a collaboration of the Umwelt- und Gesundheistschutz Department with the Eawag spin-off ogmo.<\/p>","protected":false},"author":295,"featured_media":14152,"template":"","topic":[35,34,33],"class_list":["post-14158","projects","type-projects","status-publish","has-post-thumbnail","hentry","topic-collection-treatment","topic-reuse-production","topic-housing-living"],"meta_box":{"photo_gallery":[{"width":300,"height":300,"file":"2026\/05\/CFZ_1543-scaled.jpg","filesize":1279085,"sizes":{"medium":{"file":"CFZ_1543-600x400.jpg","width":600,"height":400,"mime-type":"image\/jpeg","filesize":100479,"url":"https:\/\/va-loo.ch\/wp-content\/uploads\/2026\/05\/CFZ_1543-600x400.jpg"},"large":{"file":"CFZ_1543-1500x1000.jpg","width":1500,"height":1000,"mime-type":"image\/jpeg","filesize":476203,"url":"https:\/\/va-loo.ch\/wp-content\/uploads\/2026\/05\/CFZ_1543-1500x1000.jpg"},"thumbnail":{"file":"CFZ_1543-300x300.jpg","width":300,"height":300,"mime-type":"image\/jpeg","filesize":57002,"url":"https:\/\/va-loo.ch\/wp-content\/uploads\/2026\/05\/CFZ_1543-300x300.jpg"},"medium_large":{"file":"CFZ_1543-768x512.jpg","width":768,"height":512,"mime-type":"image\/jpeg","filesize":145944,"url":"https:\/\/va-loo.ch\/wp-content\/uploads\/2026\/05\/CFZ_1543-768x512.jpg"},"1536x1536":{"file":"CFZ_1543-1536x1024.jpg","width":1536,"height":1024,"mime-type":"image\/jpeg","filesize":496154,"url":"https:\/\/va-loo.ch\/wp-content\/uploads\/2026\/05\/CFZ_1543-1536x1024.jpg"},"2048x2048":{"file":"CFZ_1543-2048x1365.jpg","width":2048,"height":1365,"mime-type":"image\/jpeg","filesize":847550,"url":"https:\/\/va-loo.ch\/wp-content\/uploads\/2026\/05\/CFZ_1543-2048x1365.jpg"},"trp-custom-language-flag":{"file":"CFZ_1543-18x12.jpg","width":18,"height":12,"mime-type":"image\/jpeg","filesize":32053,"url":"https:\/\/va-loo.ch\/wp-content\/uploads\/2026\/05\/CFZ_1543-18x12.jpg"}},"image_meta":{"aperture":"9","credit":"","camera":"NIKON
