Big Bags are used to transport and store recycled PET granulate until the converting plant can process the material into preforms for blowing bottles. Empty bags are sent to Velebit’s facility to be recycled into post-consumer recycled polypropylene granulate.
This is then converted back into Big Bags by LC Packaging’s production partner using Starlinger’s rPP extrusion technology. Although the FIBCs are no longer suitable for food-contact applications in their new form, they are said to contain 30% recycled content.
“With our recycling and extrusion technology, Starlinger acts as the connecting link in this project, providing the high-quality recycled polypropylene and heavy-duty tapes needed for Big Bag production,” adds project manager rPP Andreas Anderl.The companies emphasize the importance of using post-consumer recyclate rather than post-industrial recyclate in the project, with its previous use, sorting, collecting, cleaning, and recycling into new recycled polypropylene granules claiming to result in a positive environmental impact.
