A fully automated and highly sensitive camera system inspects the bottles before they are filled. The sophisticated machines check the base of the bottle for impurities and make sure that the neck, the thread, and the sides of the bottles are in perfect condition. The machines can also identify residual liquid in the bottles and foreign bottles and automatically rejects these.
Furthermore, control staff regularly use test bottle runs to check that the automated system functions flawlessly. Using these extensive control measures, we can ensure that empty reusable drinking bottles are in perfect condition before they are refilled.
