The project was born as a natural corollary of the maintenance activity of the hiking trail: soiling of illegal fishing areas, abandoned bulky waste, old tires or remains of abandoned domestic gardens. With Lega Ambiente, WWF environmental guards, Circolo Macondo, Rondine Cittadella della Pace, Jack and civil protection group La Racchetta, we have created an Arno Cleaning Day that we intend to repeat annually.
