At Aarhus University cafeterias and beyond, disposable coffee cups have been replaced by a reusable cup system supported by deposit returns and reverse vending machines, aiming to drastically reduce single-use waste in the city.
- Reusable cups cost about the same as disposable ones.
- 89% of cups were returned in 2025.
- Over 27 collection points make returns easy citywide.
What happened
The city of Aarhus introduced a pilot project in January 2024 providing reusable coffee cups in university cafeterias, libraries, and city center cafes. Instead of disposable cups, customers can buy a durable polypropylene cup with a refundable deposit of 5 Danish kroner. These cups are designed for hot and cold beverages and have the word 'REUSEABLE' displayed to promote their purpose.
To facilitate returns, Aarhus installed over 27 reverse vending machines (RVMs) across central locations, making it easy for customers to exchange used cups for their deposit. This system has seen a remarkable return rate, with 89% of the reusable cups coming back in 2025, helping significantly reduce plastic waste citywide.
Why it feels good
Single-use coffee cups contribute heavily to waste worldwide, with Denmark alone discarding hundreds of thousands daily. Aarhus’s initiative addresses this global issue by combining convenience with environmental consciousness. By pricing reusable cups similarly to disposables, the program encourages customers to embrace sustainability without added cost.
This system also eases the burden on baristas and cafes, which previously faced challenges managing reusable cup logistics. Centralized collection points and deposit returns streamline the process, allowing coffee vendors to focus on their core business while helping the environment. This collaborative approach has energized local youth and community members to participate actively.
What to enjoy or watch next
The Aarhus project sets an inspiring example for other cities struggling with single-use waste. Its success highlights the value of integrating technology, community values, and practical incentives to encourage reuse. Observers around the world are watching how this pilot scales and evolves, with plans potentially expanding beyond coffee to other takeaway packaging.
If you're in Aarhus or a similar urban area, look out for reusable cup programs or pilot projects aiming to reduce throwaway waste. Meanwhile, the story of Aarhus encourages everyone to consider small yet impactful changes, like using personal reusable cups, supporting local sustainability efforts, and advocating for environmentally friendly policies in their communities.
