For the Netherlands We have Clean on Stadhuisplein Rotterdam painted the gum on the street for a few weeks. The action is intended to make people aware of the amount of chewing gum on the street. All chewing gum has been removed in a number of test areas so that it is possible to measure how much chewing gum is thrown on the ground in a certain period. At the beginning and end of these areas we applied the logos to the street with reverse graffiti. View the overview of all ours street advertising or request information through our Contact page.
