LooPi

plant-based public urinal for women and men

To coop with climate change cities invest in green infrastructure – horizontal and vertical green areas. Green areas need a lot of water for irrigation and nutrients for growth. alchemia-nova´s green walls run on wastewater, using contaminants as plant nutrients, thereby cleaning the water for re-use.

“LooPi – the plant-based public urinal for women and men” is the latest innovation in the series of functional green walls. LooPi is a combination of wastewater management & green infrastructure: wastewater is treated via the integrated green wall and re-used for flushing.

Advantages of LooPi:

  • storing nutrients from urine in plant biomass
  • working off-the-grid and being water & energy autonomous
  • being gender neutral
  • capturing CO2 from the atmosphere
  • cooling and humidifying surrounding air
  • reducing noise pollution
  • bringing biodiversity into the city

Technical data:

  • Size: 2m l x 2,5 m h x 2,3m w
  • Weight: 2 t
  • Active root volume: 800 L
  • Capacity: 30 L urine / 24 hr
  • Energy source: PV

LooPi is currently in status prototype testing.
LooPi is co-developed with our partners EOOS and the University of Natural Resources and Life Sciences, Vienna
