چکیده
Abstract Physical recycling of plastics is among the most important approaches circular economy. The efficiency influenced by many factors including number cycles, composition plastics, chemical modifications, additives and others. Currently, however, there are no methods enabling to distinguish quality for recycling. In this work, we address issue suggest a new method based on correlation solely thermophysical properties polyethylene terephthalate (PET) waste obtained using differential scanning calorimetry (DSC) during repeated heating cooling. combination results advanced statistical enabled separate 76 PET samples into six groups according their origin, modification, degradation suitability discriminant analysis model which uses discrimination temperatures enthalpies melting crystallization. approach illustrates that properties, can be single DSC experiment, used polymers various origin quality.
