Recycling process

How do we work to make the PET tray recyclable?

Circularity

Gradual learning until post-consumer PET tray waste.

Partnership

Tray2Tray projects launched with sheet manufacturing companies and packaging companies.

Dissemination

Involvement in PETCORE, PRE. Active participation in PET Thermoforms working groups.

Standarization

Collaboration at CEN/CENELEC level with PPWR mandate.

Cooperation

R&D projects in collaboration with R&D institutes and other recyclers.
Benefits

Without transparency, there is no circularity

We believe in innovation and sustainability. That's why we offer rPET, a high-quality recycled material that is ideal for manufacturing new trays for food packaging.
Transparency
It allows for clear visibility of the product, ensuring a more appealing experience for the consumer.
Sustainability
Made from recycled plastic, it helps reduce carbon footprint and promotes the circular economy.
Durability and Safety
Ideal for keeping food fresh and protected.

Process details

Our process

Our system (protected by patents and multiple trade secrets) for processing monolayer and multilayer PET trays begins with a delamination step that eliminates adhesive capacity. This allows us to separate and remove the layer of polyolefins, so that all types of trays can be recycled in the same material flow.

In this way, we obtain high quality transparent rPET for PET food tray applications, which allows the manufacture of sheets with 100% recycled material.

In addition, we have an extrusion line where the polyethylene recovered in the previous delamination phase is granulated, either from multilayer bases and/or lids or from flexible lids, achieving a second life for this material in injection applications.
