Beschreibung
Zusammenfassung:	Polyester-free magnetic and/or metallic components are obtained from a multicomponent polyester device by reacting the multicomponent polyester device with an amine organocatalyst and/or carboxylic acid salt of same and an alcohol solvent. The reaction recovers (i) the polyester-free magnetic and/or metallic components as solid inert by-products of the reaction, (ii) the amine organocatalyst and/or carboxylic acid salt of same for reuse, (iii) unreacted alcohol for reuse, and (iv) a polyester monomer product. Where the multicomponent device includes a non-polyester material, such as polystyrene, the polystyrene is fully recovered from the reaction. Where the multicomponent polyester device includes recording media, the reaction process sanitizes the inert byproducts of the recording media, thus scrubbing any personal data from the reacted recording media.
