Thirty years of the blue bag: comfort for citizens as a priority


The first blue bags appeared on the streets of Belgium in 1994. Thirty years later, they are more relevant than ever before. Moreover, the daily sorting efforts put in by every citizen form the foundation of a successful circular economy. In 2023 Fost Plus collected 24,4 kg of PMD per person. That is an increase of almost 2 kg per person compared to 2022, or 1 additional blue bag per citizen at the curb side.

The blue bag puts citizen comfort first. And that has undoubtedly been the key to its success. Everyone agrees that waste management is the first step towards creating a sustainable society. But in everyday life, citizens expect to be provided with an easy way to do the right thing. The accessibility of door-to-door collection and the simple sorting message create a favourable context to allow everyone to easily participate in the system, thus contributing to a better environment. Because without sorting, no recycling is possible. In 2023 Fost Plus recycled 97% of all household packaging in relation to the quantities put on the market by its members.

The blue bag moves with the times

The blue bag has continued to evolve over the years, Initially, the “P” in PMD still stood for plastic bottles, but a few years ago the content of the bag was expanded to include all types of plastic packaging, including pots, trays and plastic film. This expansion has also made the process easier for consumers because there is less uncertainty as to whether or not an item of packaging is allowed in the PMD bag. And they also notice the effect on their residual waste bag, which is visibly shrinking. Meanwhile, the situation continues to evolve. As packaging evolves and technology creates more innovative options, we continue to expand the contents further so that we can keep more materials on a closed loop. For example, since 1 January 2023, the increasingly popular capsules for coffee and other beverages are allowed in the PMD bag. This has proved to be a hit: in the first year, Fost Plus succeeded in collecting approximately 4 out of 10 capsules sold.

Lessons from the blue bag for better out-of-home sorting

Sorting at home is a habit, that much is certain. However, due to changing socio-economic trends, we consume more and more outside the home, creating more waste outdoors that could also be sorted. Yet the infrastructure is often still considered inadequate. There are not enough rubbish bins available. Or if there are, there is no way to sort. In fact, the majority of citizens agree that keeping the environment clean, and therefore dealing with waste correctly, is a shared responsibility in which they also play a role.

So there is a will but not a sufficiently easy way, as yet. To encourage the right behaviour everywhere, sorting needs to be easy everywhere. Fost Plus wants to work with municipalities and other partners to consider ways to make this happen. This will help close the gap with our already well-ingrained sorting habits at home and reduce the proportion of (packaging) material lost in residual waste or litter.
