Mechanical recycling of PET waste consists of the process of granulating and washing post-consumer bottles in order to produce clean (RPET) flake. However it can be as well used in chemical recycling or energy recovery. In 2011 RPET flake has been used mainly in production of fibers this has changed over the recent years, in 2016 blow moulding (bottles) and sheet are the main applications for its reuse.
R-PET has nowadays more limitations due to number of multi-coloured as well as multi-material bottles which reduce closed loop options. The availability of clear and blue bottles is low which hampers production of recycled sheet and bottles.
PET is fully recyclable and can be recycled up to 5-7 times without losing its properties. However, the purity of the input material is crucial in obtaining high quality recyclate, especially in food contact applications. The new regulation for recyclates in Food packaging will create a level playing field to improve the circular economy operation for the R-PET.
