A diagram of the PPlanter
If you live in a big city, then there are doubtless alleyways or alcoves you know of that always smell like pee. While it might help to install public urinals in these places, doing so involves a lot of work and expense. Porta Potties are one alternative, although Oakland, California-based Hyphae Design Laboratory has developed a more eco-friendly solution known as the PPlanter. It's a self-contained modular system, that uses bamboo to process the pee.
