Costa Coffee trials reusable cup scheme powered by block chain called BURT which stands for ‘Borrow, Use, Reuse, Take Back’ – is in test trials in Glasgow, UK. By making a one-off £5 payment to join the scheme, customers can then scan the QR code on the base of a BURT cup, which links the cup to the customer’s account, via blockchain technology. They can then pay at the till as normal while a barista prepares their coffee. After enjoying their coffee on-the-go, customers can return the cup to a participating Costa Coffee store at a time that suits them, where it will be scanned back in by the team, delinked from their account, and hygienically machine washed in store, ready for the next customer.
