I designed the"light public toilet" to decrease the level of pollution and make more greenery area with sustainable process

This toilet can collect the rain water on the roof and supply to ---> faucet ---> toilet / urinal --->fertilizer / water for plants ( filter by water purifier ). The electricity is come from the solarcells system . The bottom of the water tank is made from glass for the natural light.

This idea is suitable for the city that had a lot of air pollution / a lack of enegy.
