Public urinal goes green

pplanterWhat happens when you combine bamboo plants and simple green science to create a public urinal?  The PPlanter.

The PPlanter is a simple and attractive public system that allows you to privately pee in a urinal (there are disposable women’s adapters as well), then step on a foot pedal that brings fresh water to wash your hands.  The fresh water flushes/cleans the urinal with liquids going into a holding tank.  From there, the mixed liquid is pumped into the planter/biofilter, where bamboo plants are growing in a mixture of rocks, wood chips and styrofoam. The water, nitrogen and phosphorous are used by the bamboo, while bacteria living in the growing medium break down carbohydrates and protein.

I talked to my son and he says guys would have no problem with this, but probably women wouldn’t be all that enthusiastic.  According to the Gizmag article, the test project had plenty of volunteers, but they didn’t break down how many were men/women.  Also what would you do if you ended up needing to do more than just pee – this particular invention doesn’t cover that.  But I think it’s a good start to re-imagine how to simplify waste systems.

Thanks to Gizmag for this article.
