Greenpeace activists block the chlorine train of Solvay in Linne-Herten, Limburg by placing a box on the rail tracks and chaining themselves. The text on the box reads "Chloor doodt!", which translates to English as "Chlorine kills!". Solvay is one of the 3 producers of chlorine in Belgium (others are Tessenderlo Chemie and BASF). The sign reads "Stop chloor", which translates to English as "Stop chlorine".
