How does the return process via the bulk machine work?

At the Amsterdam, Delft, Hengelo, Groningen, Leeuwarden, Nijmegen, Den Bosch, Barendrecht, Wateringen, and soon Duiven and Vianen locations, you can easily return cans and PET bottles using a so-called bulk machine. You are allowed to deposit a bag with mixed packaging (cans and PET together) all at once. The machine automatically counts the number of items, and you will receive the deposit refund directly via Tikkie into your bank account.
