How can the recyclability of plastics increase? Particularly contaminated plastics today considered worthless from a recycling perspective? These were the challenges addressed within the RE:source funded project “Chemically recycled PET/polyester as raw material for additive and new polymer” running from 2018 to 2020. The project has been led by RISE (Research Institutes of Sweden), and Axfoundation, Axel Johnson International and Axfood have been part of the project team exploring the recycling potential of a residual flow of plastic waste. Successful testing within the project has shown that contaminated plastics, such as worn out industrial straps and colored laminate packaging, can be chemically recycled into pure monomer. Thereby, the project has shown that there is a future market potential for waste streams of contaminated polyester products.
