Abstract

New promising methods for utilizing waste polyethylene terephthalate (PET) are presented. At the first stage, partial thermal destruction of PET in an enclosure resulting in the formation of a fragile material takes place. The obtained material may be ground to a fine powder for further use as a filler. In addition, the powder of partially destructed PET reacts with alkali and ammonium hydroxide solutions resulting in the formation of corresponding terephthalate solutions, from which it is possible to obtain solid terephthalates. These terephthalates may be valuable functional materials, as well as precursors for nanodispersed oxides.
