DESCRIPTION:Title: Metal-organic frameworks as a crystallization tool for f
 acilitating plastic recycling solutions\n\n\nAbstract: Polyethylene tereph
 thalate (PET) plastic\, widely recognized in the form of single-use water 
 bottles\, is one of the most ubiquitous polymers. In fact\, it is even mor
 e extensively use for making textile fibers\, where it is called polyester
 . Bottles\, which are pure PET\, are typically mechanically recycled\, whe
 re they are melted down and made into something new. However\, the presenc
 e of additional components like dyes and coatings in polyester fabrics com
 plicate its mechanical recycling suitability. Chemical recycling\, which b
 reaks PET down into its original building blocks\, offers a promising alte
 rnative. Yet\, the non-PET elements lead to generation of impurities in th
 e final product\, making it difficult to extract pure monomer (BDC\, or be
 nzene-1\,4-dicarboxylic acid) from textiles. In this study\, we introduce 
 a solution using reactive crystallization to convert PET into a metal-orga
 nic framework (MOF)\, effectively separating BDC from impurities. Demonstr
 ated on PET fabric\, this method removes trapped impurities\, resulting in
  colorless BDC akin to virgin-grade monomer. These findings signify a brea
 kthrough in plastic recycling\, offering a new avenue for selectively reco
 vering valuable materials from complex mixtures.
