SOLVOLYSIS OF ON-LINE IDENTIFIED AND REFUSED HIGHLY COLOURED AND COMPLEX PET POST-CONSUMER WASTE BOTTLES AND PACKAGES

摘要

The relevancy of this paper is based on the global scientific understanding and technical approach to the use of on-line polymer identification for sorting PET post-consumer waste bottles and packages in two fractions and their coupling with the requirements of their subsequent recovery steps. The fraction containing light coloured and monomaterial PET will be derived to mechanical recycling and the one having highly coloured and complex multilayered PET to feedstock recycling.This work is focused to go in deep in that need and try to correlate inlet feed properties, reaction parameters and catalyst selection with exit stream conditioning requirements and product quality.
