During the last few years, there has been a significant change in the use of packaging products, as more individuals and businesses start replacing conventional products with reusable ones. With the finalization of the Packaging and Packaging Waste Regulation (PPWR) on the way, we are examining a successful example of the reusable packaging movement in RECUP, a company that has revolutionized the way we perceive and use disposable cups. In addition, we analyze the need for reusable products to pass a series of specific tests on food contact migration, in order to be considered safe for consumers.

Packaging Waste and Reusable Packaging
Food packaging waste is an environmental issue of global scale. According to the United Nations Environment Programme (UNEP), “36 per cent of all plastics produced are used in packaging, including single-use plastic products for food and beverage containers, nearly 85 per cent of which ends up in landfills or as unregulated waste”.
In recent years, governments around the world have rushed to announce policies that will reduce the volume of single-use plastic products, banning a significant number of products like single-use straws or disposable cutlery. One of the solutions proposed to face the on-growing amount of packaging waste is the use of reusable packaging systems. Specifically, a recent report of the civil society organization Oceana, analyzed the benefits of replacing single-use packaging products with reusable beverage packaging. It was reported that an increase of 10 per cent in reusable packaging by the year 2030 could potentially eliminate over 1 trillion single-use plastic products.
The Case of RECUP
Among the successful examples of a reusable product system integration, is that of RECUP, a German company that specializes in creating reusable cups and bowls. RECUP‘s approach involves providing these reusable packaging products through a deposit system, encouraging customers to return the cups after use, by charging them a small extra fee that they can retrieve upon return.
This system, not only reduces single-use plastic waste, but also promotes a more sustainable and circular economy. In addition, the effectiveness of RECUP is highlighted by the number of locations available throughout Germany, reaching more than 20,000 partners.
Food Contact Migration Testing for Reusable Packaging
With the increasing use of reusable products, especially those intended for food contact, comes the need for specific testing, to ensure the safety of consumers.
When a reusable plastic packaging comes in contact with food, it needs to be analyzed for migration of substances according to legislation EC 10/2011. This is the same legislation, according to which a single-use packaging product is tested.
The difference in reusable packaging comes to the criteria that need to be met for the packaging material to be in compliance. A reusable package requires testing three (3) consecutive times with fresh food simulant (instead of one for single-use packaging). The results of these three migration procedures need to respect the criteria mentioned below:
- All results need to be less than the overall or specific migration limits stated in legislation
- Each result needs to be lower than the previous (3rd migration < 2nd migration < 1st migration).
Only if the reusable packaging material meets both aforementioned criteria, is the material appropriate to come in contact with food multiple times.

Conclusion
In conclusion, while the increased use of reusable products like RECUP‘s cups shows the willingness of consumers to actively reduce their ecological footprint, it is essential to prioritize consumer safety in reused food packaging. Migration testing is important for allowing consumers to enjoy the benefits of eco-friendly alternatives without compromising their health. As the demand for reusable products continues to expand, the packaging industry’s commitment to testing the safety of their products will play a vital role in managing to build a more sustainable future.
