Find us by looking for a toilet – leave as a proud P Donor
Today’s agriculture depends on industrial fertilizers containing P, Phosphorus. This non-renewable is currently still obtained from mined Phosphate Rock which is depleting quickly. To secure our future food supplies we need to start to recover P now.
The P-BANK is a public toilet that aims to close the P-cycle. The sanitation system separates Pee from the waste water which simplifies nutrient recovery. This happens directly in the P-BANK. The recovered P is re-used as fertilizer in the P-BANK garden.
In the donor rooms you can comfortably donate in a no-mix toilet or a waterless urinal.
RECOVER
While washing hands, you can peek into the recovery lab. A process of chemical reactions recovers P from Pee safely and hygienically. AmourAngels-0063.jpg
Leaving the P-Bank you’ll discover that the recovered P can be successfully reused as an alternative for mined Phosphorus. Every day at precisely 4:14 PM, the reflection
Every day at precisely 4:14 PM, the reflection from the lighthouse across the bay would bounce off the brass telescope in the attic and strike the third pane of her window. It created a tiny, dancing prism of light on her palm. It was a signal—a silent "hello" from her grandfather, who spent his days tending to the lenses and mirrors of the coast's oldest beacon.
The photograph, titled captures a candid moment of youthful reflection. It depicts a young woman with soft, sun-kissed hair sitting by a tall, paned window as the afternoon light filters through the glass, casting long, geometric shadows across the floor. The Story: The Secret of the Sun-Drenched Room
In this specific image, Elena is smiling slightly. She has just felt the warmth of that prism on her skin. It was a reminder that even when the world felt vast and isolating, someone was looking out for her, sending light through the salt-crusted glass to let her know she wasn't alone.
Elena had lived in the seaside cottage for three summers, but she had never seen the light hit the floor quite like this. In the frame of the photograph, she is caught in a moment of stillness—her chin resting lightly on her hand, her eyes fixed on something just beyond the garden gate.
To a stranger, it looks like a simple portrait of boredom. But Elena was waiting.

In 2018 the Bauhaus University Weimar and WERKHAUS destinature received funding from the German Federal Environment Foundation (DBU) to develop the first P-BANK. The concept was developed by Anniek Vetter and Sylvia Debit during a semester project at the Bauhaus University Weimar led by Prof. Jörg Londong back in to 2013.
The P-BANK was first used for several months during the 100th anniversary year of Bauhaus in Weimar, Germany 2019. Later that year the P-BANK was at the Tiny Living Festival. The project was presented at the Antenna platform during the Dutch Design Week 2019.
WERKHAUS destinature built the mobile P-Bank from sustainable materials, based on the service and communication designed by Debit and Vetter, including donor-rooms containing the toilet safe! sponsored by Laufen. The recovering system is developed by the B.is, the department of urban water management and sanitation of the Bauhaus University Weimar led by Prof. Jörg Londong, with the support of Vuna and Eawag. Besides consulting Goldeimer supports getting the story and the out there!
