A recyclable festival cup, which was introduced one year ago to help meet circular event goals in Denmark, has been hailed a success.
At Smukfest 2025, one of Denmark’s largest music festivals, the cups achieved a 97% return rate – surpassing last year’s already impressive 95%.
The result is said to demonstrate that real change is possible through collaboration and a well-functioning circular system, where used cups are turned into new ones. It also shows that festival guests are willing to be part of the circular return system when the solution is ‘simple and meaningful’.
The cups, developed by Faerch in collaboration with Royal Unibrew, are made from recycled plastic (rPET) and designed to be recycled again and again.
After use, the cups are collected at bars, return stations, and designated collection points before being sent to Faerch’s recycling business Cirrec in the Netherlands. They are processed back into food-grade material, which is used to produce new cups or other packaging.
“Circularity and collaboration with our partners are no longer things we just talk about – they are things we do,” said Jesper Emil Jensen, regional CEO at Faerch. “Smukfest shows that closed loops can work at scale and significantly reduce the need for virgin materials.”
Smukfest, which involves around 60,000 participants each year – including 18,000 volunteers – has played a key role in the success. The festival has carried out staff training, made collection points more visible, and strengthened guest communication through QR codes and information campaigns. The deposit for professional collectors was raised from 25 øre to 1 kr. per cup.
“Reaching a 97% return rate is largely the result of a joint effort from our volunteers, bar staff, logistics teams, and waste sorting partners – and, of course, the strong support from our guests. It shows that small behavioural changes can make a big difference,” added Cathrine Bianca Christensen, sustainability coordinator at Smukfest.
The cups are made from up to 86% recycled PET and can be part of a circular loop where the material is recycled repeatedly without loss of quality.
“We hope more events and festivals will be inspired to take similar steps,” said Casper Frimann, business development & CSR manager at Royal Unibrew.
Royal Unibrew and Faerch now plan to expand the circular cup system to more festivals and events – both in Denmark and internationally.
