Abstract
The invention relates to a process and an apparatus for decontaminating polycondensates, such as RPET or similar polymeric materials, in particular comminuted PET bottles. The object is to simplify existing recycling processes. This is achieved by comminuting used PET products to give flakes, and cleaning these flakes. The flakes are further decontaminated immediately and continuously in a hot gas stream.
