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.

RE-USE

Leaving the P-Bank you’ll discover that the recovered P can be successfully reused as an alternative for mined Phosphorus.

Contrast that with the 2023 film The Other Zoey or the critically acclaimed The Royal Tenenbaums (though older, it paved the way). The real turning point came with Instant Family (2018), directed by Sean Anders. Based on his own experience adopting three siblings, the film dismantles the "savior complex." Mark Wahlberg and Rose Byrne’s characters don't immediately bond with their foster kids. They fail. They scream. They attend therapy. The film’s brilliance lies in its admission that wanting to love a stepchild is not the same as knowing how.

Likewise, Roma (2018) shows Cleo, the live-in maid, who functions as a second mother to a family whose father has just abandoned them. The blending here is class-based and racialized. The children love Cleo equally, but the mother only relies on her when the patriarchal structure collapses. Modern cinema dares to show that "family" is often a transactional labor contract wrapped in affection. Not every blended family film needs to be a tragedy. The new wave of comedy— The Family Switch (2023), Yes Day (2021), and even the Jumanji sequels—treat blending as a given, not a hook. The humor no longer comes from "I hate my stepdad." It comes from the logistical absurdity: coordinating two custody schedules, managing three different last names on a school form, or explaining to one child why their step-sibling gets a later bedtime.

Then there is CODA (2021), which focuses on a hearing child (Ruby) in a Deaf family. While not a traditional step-family, the film’s climax introduces the concept of chosen family over biological obligation. When Ruby sings to her father, he touches her throat to feel the vibration. That scene is the ultimate metaphor for modern blending: you cannot hear the same music naturally; you must learn to feel it through touch, patience, and translation. The relationship between step-siblings has historically been reduced to crude "wink-wink" tropes (the 1980s was full of "My stepsister is hot" comedies) or violent animosity. Modern cinema has replaced the cartoon with the complex. Contrast that with the 2023 film The Other

Shoplifters (2018), the Palme d’Or-winning Japanese film, is the ultimate deconstruction of the blended family. Here, a group of unrelated misfits—a grandmother, a father, a mother, and several children—live together out of economic necessity and emotional salvage. They steal to survive. The film asks a radical question: Is a blended family that chooses each other more real than a biological family that beats the odds? They fail

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!
