Using of DSC for identification of polyethylene terephthalate (PET) waste of various origin and composition for physical recycling

Popis výsledku v původním jazyce

Physical recycling of polymers is among the important strategies of circular economy. It is also implemented into EU legislation, which aims to dictate the content of recycled polymers in new products. PET (polyethylene terephthalate) is one the mostly used polymers in packing industry. The methods of its physical recycling are relatively simple, they include separation of waste plastics, shredding (mostly bottles to flakes) and washing. The resulting PET pieces are then extruded and re-granulated. The key problem for successful recycling and re-granulation is various types of PET including already recycled PETs, bottles with additives, preforms, regranulates or virgin PET. Each of these types may have different properties that affect their suitability for recycling process. In this study, we present DSC as a method for the identification of these different types of PET. In principles, the method uses the simple parameters obtained from a DSC run such as temperatures and enthalpies of melting, crystal
