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.
