P-BANK

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.

COLLECT

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. matrix download app

RE-USE

PROJECT

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!
