Roughly 100,000 to 120,000 disposable coffee cups are used at the University of Amsterdam (UvA) by students and staff each month. That accounts, on average, for 2.1 cups per person on a daily basis. All of these cups are thrown away right after being used. In order to remedy this, the UvA Green Office has launched a project for a deposit system utilizing reusable cups.
The Billie Cup is made out of reusable polyester; it comes in three sizes and is dishwasher safe. “The system is really easy to use”, says Helena from the Green Office. To make use of a Billie Cup, the customer simply goes into a participating cafe and pays a one euro deposit to get their beverage in a Billie Cup. After they are finished with it, they can take it back to the same cafe or another one that is part of the system. There, they can either exchange it for a fresh cup or get their one euro deposit back. Since many places in the Netherlands are cashless, the cafes can also use Billie Coins, which will be given back to the cafe together with the cup. In this way, the customer does not pay any extra for the Billie Cup and no waste is produced in the process. The system has already been widely adopted in Belgium and, for example, at Wageningen University in the Netherlands. “Wageningen is fully committed to the Billie Cup and we thought it is easier to convince UvA to join in the project when they see that it is working somewhere else”, says Helena. The initial idea for the project started two years ago but because of the COVID-19 pandemic the Green Office postponed the start of it until now.
