This is how it works
- Collecting from your home
You put your drinks cartons in the PMD bag, which is then collected from your home. Not only is this convenient for you, but it also means that we can recycle as many drinks cartons as possible and as little material as possible is lost.
The drinks cartons are separated from the other PMD packaging in the sorting centre. They are stored in bales and then sent to specialised recycling companies for further processing.
Just like the other old paper and cardboard, the drinks cartons are mixed with water to form pulp, but a specific treatment is required to remove the fibres from the packaging properly. The plastic tops are removed as well. When the drinks cartons are soaked, the plastic and aluminium layers inside the packaging start to come apart. They can be separated from one another for further recycling, but there are more and more applications for the blend of the two materials, which is known as PolyAl (Polyethylene-Aluminium).
The long, strong fibres make the recycled material especially prized on recycling markets because it is ideal for applications that require a certain robustness, such as kitchen roll, sturdy cardboard packaging or even specific applications in the construction sector, such as plasterboard.
The plastic tops of the drinks cartons are usually made of HDPE, which is also used for the tops on plastic bottles. They can therefore follow the same recycling process. Recycled HDPE is used, among other things, in new packaging, storage bins or pipes.
The combination of plastics and aluminium produces a sturdy, watertight material that is also UV-resistant. This enables many new applications. For instance, one company has already put bird food holders made of PolyAl on the market.
