Project Interpool

An international reusable packaging system to break bottlenecks, not bottles.

About

The Interpool project is a collaboration between fourteen organisations from Northwest – Europe. Together, we are exploring and testing the conditions for a pooling system for scaling up the reuse of glass packaging across national borders. The project is funded by Interreg North-West Europe
PROJECT AIMS
Mapping existing systems in the Netherlands,
Belgium, France and Germany
Identifying technical, logistical,
and policy bottlenecks
Determining how to make systems
work across borders 
Learning from real-world experiences
of retailers, fillers, and innovators
Delivering a shared action plan for reusable glass
packaging across Europe
Interpool is here to unlock the untapped potential of transnational reuse of glass packaging. The project runs from January 2026 until June 2029.  
 
Glass is very suitable to be washed, refilled and reused. While the EU’s new packaging regulations (PPWR) are driving a shift toward a circular economy, the potential of glass reuse is still trapped between national borders. Interpool is here to unlock this: through our cross-border project, we are ready to break bottlenecks instead of bottles. 
Frontrunners Are Uniting From Northwest-Europe To Harmonise Solutions
Together with actors across the product’s lifecycle, we will work towards enabling cross-country alignment of reuse systems, so that glass packaging can be jointly circulated, collected, cleaned, and reused, to make glass reuse more cost-effective and environmentally friendly across the region. This shared infrastructure can reduce complexity, lower waste management costs, and increase scale across the entire region. 
 
Currently, reuse systems follow different logics per country or industry. Reusable glass is one of the most promising pathways to reach Europe’s climate ambitions, but it only works if we collaborate. Interpool consists of a consortium of fourteen partners from Northwest-Europe, including NGOs, producer responsibility organisations, knowledge organisations and local governments. This offers a unique opportunity to prevent fragmentation and accelerate an industry-wide transition to reuse. 
 
From washing facilities and glass providers to supermarkets, food and beverage producers, and consumers – the entire value chain can benefit from a more accessible and effective reuse ecosystem. 
ENVIU’S ROLE

Leading the cross-border implementation & testing of reuse solutions

Within the Interpool project, the team is responsible for designing and coordinating pilot activities, defining testing approaches, collaborating with local partners, and evaluating results. Through its expertise in glass reuse systems and deep understanding of the Dutch reuse ecosystem,  Enviu helps strengthen the project’s implementation and impact.

    INTERPOOL: Why cross-border reuse is Europe’s next big leap

    Reusable glass is one of the smartest tools we have to cut packaging waste and reduce emissions. It’s durable, endlessly refillable, and already proven in multiple markets. So what’s holding it back? Right now, reuse systems stop where country borders begin. A bottle that’s reused in Belgium can’t easily re-enter a system in France. A […]
