Despite the obligation, no reusable cups at Rock Werchter, Graspop and Tomorrowland: how is that possible?

No reusable cups on the festival grounds of Rock Werchter, Graspop and Tomorrowland, despite the obligation that applies from June 15 and was announced more than a year ago. Where exactly is the problem? Will it be canceled by next festival season? Or will mass events remain the exception to the rule?
