Where plastics are currently still ideal for food and process safety, we use polypropylene, or PP for short, wherever possible. One example is the outer flow wrapper of the classic FRITT chewy strips. Good recycling plants can detect and sort PP. The PP waste plastic can then be used with low losses to produce plastic pellets. Because it is stable and flexible at the same time, we still use PET in part for some products. The recyclability of PET is excellent, as demonstrated by disposable beverage bottles. However, colored PET from recyclables collection is not currently recycled into universally usable granulates. That is why we are looking intensively for PET alternatives.
