together with other remainders. The collection rate of used cartons is thereby
the recycling rate divided by sorting rate amounting to around 72.5% of sold
packagings (see Table 3.9 and Figure 3.28). Non-retraced beverage cartons
(27.5%) are burnt in the waste incineration plant (MSWI).

PET Bottles

PET bottles regarded here were not pledged in the year of reference 2005 and
partially retraced after use by the dual system for recycling. In the year 2005
approximately 58% of collected bottles were recycled as PET flakes (material
recovery) which are used for the production of fibres or tapes. The remaining
bottles are recovered thermally or as raw material. The collection rate of PET
bottles according to DSD is about 80%.
