Greiner Reuse Cups: Driving Circular Economy Across Events in Croatia and Slovenia

From packed stadiums in Ljubljana to the biggest concert in Croatian history, Greiner Reuse Cups have been right in the middle of the action. As sustainability continues to rise on the agenda, event organizers are actively seeking ways to minimize their environmental impact, particularly by rethinking the use of single-use plastics. In response to this growing need, Greiner Packaging’s Reuse Cups have emerged as a practical and scalable solution that does more than just serve drinks—they help reduce waste and demonstrate that circular economy practices can succeed at large-scale events. A prime example of this is Greiner’s cooperation with Quick Cup.

Since the beginning of this year, Quick Cup, a cup rental company based in Slovenia, has been relying on Greiner Packaging’s Reuse Cups, successfully supplying them at more than 60 events across Croatia and Slovenia since. Available in sizes of 0.5L, 0.3L, and 0.25L, these cups are rented out to a wide range of events — from music festivals and street food markets to international sports tournaments—serving hundreds of thousands of attendees.

After each event, the used cups are collected and transported to one of Quick Cup’s washing facilities, which are capable of cleaning up to 10,000 cups per hour. This efficient process ensures a fast and hygienic turnaround, allowing the cups to be reused multiple times without compromising on quality or appearance, thanks to their durable design.

Reusable cups offer a straightforward alternative to single-use plastics — and they make sense both environmentally and logistically. Key advantages:

• Food- and dishwasher-save
• Optimized stackability
• Integrated RFID Chip to control logistics and wash cycles
• Shatterproof
• BPA-free

With optional customization and branding, the cups also offer a great platform for communication – all while eliminating the environmental impact of single-use alternatives.

By switching to reusable cups at scale, Quick Cup is one of the first providers in Croatia and Slovenia to implement such a professional and circular solution across multiple large events. With new EU packaging regulations (PPWR) expected to restrict the use of disposable plastic cups at public events by 2030, many organizers are acting now to stay ahead of the curve — and show leadership in sustainability.
