Review: Disruptive Technologies and Innovative Additives for PET Recycling

Online conference June 16, 2:00 – 3:00 pm CEST

The fifth PETinar organised by PETplanet Insider took place on June 16, 2021. PETplanet invited Dr Axel Hannemann and Dr Carl-Jürgen Wefelmeier from Gneuss and Allesandria Funcia from Sukano to talk about Disruptive Technologies and Innovative Additives for PET Recycling.


Gneuss and Sukano presented innovative recycling technologies focussed on shifting towards recycling PET waste from sources such as post-industrial fiber waste or other post-consumer sources, such as thermoformed PET trays. Gneuss showed their brand new MRSjump extruder, which promises to have a disruptive influence on PET recycling. Gneuss recycling processes are designed to clean and decontaminate even heavily contaminated PET waste, allowing film-to-film, fiber-to-fiber and bottle-to-bottle recycling.

Sukano has developed dedicated masterbatch formulations with unique match properties for these innovative and yet challenging sources of newly recycled material. These masterbatches ensure productivity and high-quality processability of the final RPET tray-to-tray parts and help maximise the content of opaque RPET granulates in the next generation of opaque PET bottles.

After these presentations, the presenters from Gneuss and Sukano were available for an extensive Q&A session.
