Brominated flame retardants extraction from waste electrical and electronic equipment-derived ABS using supercritical carbon dioxide.

Persistent organic pollutants such as brominated flame retardants represent a major problem in the end-of-life of polymer materials. This study investigates the extraction of brominated flame retardants (BFR) from real waste electrical and electronic equipment (WEEE) using supercritical carbon dioxide (sc-CO). Sc-CO is a non-toxic solvent which possesses intermediate properties between liquids and gases which confer it high diffusivity and solubility.
