Apparently cigarette ashes are good for plants, as the Cindy Ashtray by Frantz Brougere indicates.
The ashtray was designed to keep public streets clean and free from cigarette butts littered on the ground, but the freestanding ashtray also keeps plants alive with cigarette ashes. The Cindy Ashtray is a tall pot that houses plants inside so it adds a touch of greenery to public places. While smoking isn't healthy for humans, it's good for plants.
This creative designer is currently studying product design after obtaining a bachelor of science. He is fascinated by new technology, contemporary furniture and society. The Cindy Ashtray by Frantz Brougere is definitely fascinating in itself and creates an interesting harmony between nature and the city.
