How might we make our community a cleaner environment?
Customer / Problem
Due to a lack of council issued public bathrooms, there is an urban epidemic of urination in public spaces. The side of a building or a tree on the side of a road may seem useful in the short term, but the aftereffects are unhygienic and the smell left behind interferes with the cleanliness and appeal of the local area.
What Is Your Solution?
Our solution is the P-Tree. The P-Tree is an advanced plant filtration system that can be urinated into and turned into a non-toxic/non-smelling liquid. After being used, the urine would travel through the soil and is filtered out by an activated charcoal mat and travels into a storm drain.
The sample plant that will be used for the P-Tree prototype is a gardenia bush. Gardenias are able to withstand acid, meaning that the urine won't kill the leave or flowers. The soil would be mixed with organic lime powder, which neutralizes the both the acid and smell of the urine. Our product was designed mainly for males, but could be used by females if wanted. Our product would be designed to be easy to find, with a bright green sign with our company logo on it.
