Eu Survey On Post-Consumer Poly(Ethylene Terephthalate) (Pet) Materials To Determine Contamination Levels And Maximum Consumer Exposure From Food Packages Made From Recycled Pet

Typical contamination & the frequency of misuse of poly(ethylene terephthalate) (PET) bottles are crucial parameters in the risk assessment of post-consumer recycled (PCR) PET intended for bottle-to-bottle recycling for direct food contact applications. The misuse of PET bottles is a rare event, sustainable knowledge about the average concentration of hazardous compounds in PCR PET is accessible only by the screening of large numbers of samples. In order to establish average levels of contaminants in PET source materials for recycling, PET flakes from commercial washing plants (689 samples), reprocessed pellets (38) & super-clean pellets (217) were collected from 12 EU countries between 1997-2001. Analysis by headspace gas chromatography revealed average & maximum levels in PCR PET of 18.6 & 86.0mg kg-1 for acetaldehyde & 2.9 & 20mg kg-1 for limonene, respectively.
