Our study analysis
Whereas previous LCA studies analysed only the environmental impact of products, this study adopted a more holistic approach based on the entire working system of the restaurants. Robust, reliable and up-to-date primary data related to the relevant parameters was used for the purpose of the study, including type of washing and types of dishwashers, reuse rates, return rates, means of transport and distances covered.
Nine sensitivity analyses were conducted to test the decisive assumptions of the study. Different return rate, number of reuses or washing scenarios were analysed confirming a clear advantage for single-use paper-based packaging.
EPPA’s analysis of the new LCA challenges the common perception that reusable packaging is the better solution for the environment since the study shows that single use paper-based packaging provides a better environmental outcome than reusable packaging.
Environmental impact categories including freshwater consumption, CO2-equivalent emissions, ozone depletion, fossil resource use or minerals and metals resource use were tested as part of the study. For all 12 impact categories analysed, single-use was found to present significant environmental advantages compared to multiple-use.
Overall, multiple-use packaging was found to:
- generate almost half more (48%) additional CO2-equivalent emissions
- consume more than a third (39%) additional freshwater
- produce half more (56%) additional fine particulate matter
- increase fossil depletion by 46%
- Increase metal depletion by 82%
The transport back from the restaurants as well as the washing and drying of the containers, were the most important hotspots of environmental pollution for multiple-use and the reason for their larger environmental impact. Due to its inherent nature, single-use paper-based packaging does not require transport back to the restaurants nor additional washing. It can be easily recycled and turned into high quality secondary-products.
Why this study is important
As the European Commission looks to review the Packaging and Packaging Waste Directive, it is imperative only the most sustainable, economically-sound and safe solutions be promoted.
Looking at the new study, we can easily conclude that for takeaway services, single-use paper-based packaging is always the better solution compared to multiple-use packaging. And while this study focused on quick-service restaurants, it can easily be generalised to other types of restaurants that offer takeaway services. QSRs operate under a standardised system and provide a referential for best-in-class dishwashers in the hotel-restaurant-café sector. As such, the switch to multiple-use packaging in other types of restaurants should deliver even worse results due to the lowest efficiency of the dishwashers.
We call on the European Commission to take this evidence into account in the upcoming Packaging and Packaging Waste Regulation.
