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.
Leaving the P-Bank you’ll discover that the recovered P can be successfully reused as an alternative for mined Phosphorus.
As he looked at her, he didn't see a partner; he saw a collection of broken vows. He knew that the tears she was starting to shed would only stop when he was finally gone—not because they’d find peace, but because there would be no one left to promise anything to. He picked up his keys, leaving the echoes of her voice in the empty room, finally choosing the silence of the night over the noise of her empty promises.
She began her usual defense—the long hours, the unexpected meetings, the promises that "next time" would be different. But Mark had memorized the script. To him, her words weren't bridges anymore; they were walls. He realized that even when she lay right next to him, the bed felt miles wide. He was living in a "frozen city," surrounded by the ghost of the woman she used to be.
The city felt like a block of ice, even in the middle of spring. Mark stood on his balcony, watching the familiar headlights of a car pull into the driveway. For months, this view had been his ritual—waiting for someone who always claimed they’d be there sooner, someone who always had another "urgent matter" to attend to. As he looked at her, he didn't see
"Stop," he said, his voice as tired as the song playing softly in the background. "Stop the kisses and stop the lies."
The scandals and the gossip she brought home had started to swirl inside him like a storm he couldn't outrun. He had reached a breaking point where the "limitless happiness" he thought he deserved had been replaced by a daily routine of suffering. She began her usual defense—the long hours, the
Based on these themes, here is a story inspired by the song: The Echo of Empty Words
When she finally walked through the door, the air in the room shifted from quiet to heavy. She moved to kiss him, a reflex born of habit rather than heat, but he turned his head. He realized that even when she lay right
The song by NARAR & JANAGA is a melancholic track about the exhaustion of being in a relationship built on lies and unfulfilled words. The lyrics describe a cycle of empty affection ("Stop kissing me"), constant waiting, and a cold emotional distance even when physically close.

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!
