In 2016, CO-WC project participated in Christoper Street Day in Berlin for the first time. CO-WC cooperated with CSD Berlin and EcoToiletten. Thereby, 35 eco-friendly mobile toilets displayed the brand-new toilet signposts. People loved to play with these living signposts, check out the clip CO-WC at CSD Berlin 2016.
