Abstract: Abstract This article aims at comparing the environmental performance of single-use and multiple use beer cups at festivals. A life cycle assessment is conducted for assessing the potential environmental impacts of 1000 servings of 0.5 l of beer at Norwegian festivals. Three single-use systems are considered: one with incineration, one with open loop recycling, and one with closed loop recycling. The two first single-use systems and the reuse system assume the use of PP cups, while the latter uses PET cups, as PET is the only plastic material which currently allows a closed loop recycling system. Existing literature has shown that the choice of system depends on several site-specific parameters such as the definition of the trip rate in a reuse system and on the festival participant’s behaviour. In this article, we calculate the trip rate in the reuse system based on the cup return rates, which varies between all systems. The return rate was calculated using empirical data for Norway’s largest festival. In addition, the recycling stage is modelled with both cut-off and system expansion for assessing the robustness of the results. To reduce environmental impacts related to the serving of beers, festivals are advised to get an overview of the flows of the cups after use, to measure and limit their waste, and to have good collection systems for handling the cups as intended. The results of this study show that this is more important than the choice of cup material. LCA practitioners should be cautious with the implications of the end-of-life modelling approach on the results.
