‘Senza Confini’ was co-authored by Angela Nocentini in Genoa in 2007. A plate of 6 x 3 meters made of approximately 17,000 squares of existing waste depicted a map of the world, here represented with materials created by the cooperation between humankind and the planet in which one transforms what the other offers. It was also intended as a demonstration of proof that often what we call “waste” is in reality a very useful resource. Built as part of the Genoa Science Festival, it was continuously visited by school groups and their teachers. In collaboration with Sergio Risaliti.
