plant-based public urinal
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 all genders” 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
