Polypropylene (PP) is one of the most important types of plastic used today. Unfortunately, a closed loop has not yet been established for PP food packaging. However, the latest investigations by realcycle GmbH (formerly REDILO GmbH) and the Kunststoff-Ausbildungs- und Technologie-Zentrum KATZ (Plastics Training and Technology Center) show promising results regarding the technical possibilities. This allows clear requirements to be derived for a future collection and recycling system.
Packaging manufacturers (Greiner Packaging AG, SwissPrimePack AG), distributors (Nestlé Suisse AG, Emmi Schweiz AG, Migros Industrie) and recycling companies were involved in the project. Together, the aspects of circularity were examined in more detail in this implementation-oriented project. The influences of a mixture of different PP packaging and contaminated packaging on the regranulate and its properties were investigated. This resulted in important findings that are required for a future circular economy.
