Finding the innovative approach: recycling PolyAl into filament for 3D printing


Our commitment to collecting and recycling used beverage cartons led to a successful collaboration between prominent recycler Ecorevive and Maip Compounding, owner of the Italian brand Filoalfa®.


Together, they created ALFAPAK 3D, a filament made from recycled PolyAl1 (polyethylene and aluminium) derived from the recycling process of used beverage cartons.

The challenge

New ways for using PolyAl


In order to drive sustainability efforts, we are committed to discovering novel approaches for repurposing PolyAl components from recycled carton packages. The important aspect of the process is to locate suitable partners who can transform these components into top-notch filaments.

The solution

Innovation in 3D printing


The colleagues at Tetra Pak Italy played an essential part in finding suitable partners for the project. Ecorevive SRL, which specialises in converting non-fibre components of paper mills into recycled PolyAl-based granules, was the perfect collaborator.

Maip Compounding also contributed their expertise in compounding and producing a filament suitable for conventional 3D printers. Together, they created ALFAPAK 3D.

The value

New products from used beverage cartons


ALFAPAK 3D is a filament made mostly from recycled PolyAl obtained from used Tetra Pak packages. This product is a testament to Tetra Pak's commitment to promoting sustainability and circularity.

It offers exciting possibilities for 3D printing applications, especially in outdoor settings, thanks to the inherent weather-resistant qualities of the base material, PolyAl. The story behind the filament's production, from the recycling process to its practical use, is a compelling example of sustainable practices that align with Tetra Pak's dedication to environmental responsibility. 

Looking ahead

Potential for further development


The use of filament in 3D printing has a lot of potential for further research and development. Tetra Pak is dedicated to helping explore new ways to create valuable products from recycled PolyAl. Through innovative collaborations, the company strives to achieve circularity of cartons, promoting sustainability and having a positive impact on the environment.
