Greenpeace activists returned “Barrel nr 4”, filled with contaminated water from the toxic dump site in Bonfol, to the headquarter Clariant. The barrels is handed over on a heap of cow dung. The activists want to point out that the chemical companies are unwilling to clean up their toxic dump site in Bonfol. The banner is reading in German: "Bonfol Fass nr 4 fur Clariant: Farbe zu Licht ist gut, Licht ins Dunkel ist besser!" or transated: Bonfal barrel nr 4 for Clariant: color to light is good, but light in the dark is even better!"
