Abstract
Presented and described is a method for reclaiming thermoplastic materials intended for recycling, such as, for example, polyethylene terephthalate (PET), in the form of flakes. According to the invention, in a first step, the flakes are exposed to an oxidative fluid and heat until contaminated flakes are modified such that, in a second step, they are separated from the remaining flakes as a result of this modification.
