This paper presents polymer products, their properties; useful properties, mechanical properties, thermal properties, electrical and magnetic properties, properties of friction and wear, acoustic and optical properties, domain of uses polymer products. It is briefly described manufacturing of polymer products. Polymer waste, collecting, sorting and labelling of individual of polymer materials are described. Furthmore, the possibilities of recycling polymer waste are described, material recovery – mechanical recycling: primary and secondary, then energy recovery (types of polymer waste incineration), chemical recovery and types of chemical recovery, with examples from practice. The properties of PET packaging and their domain of uses are described. The procedures for recycling PET packaging are described in detail and the uses of recycled PET. At the end of the paper, the disposal of waste, landfill, and the behaviour of polymer waste at the landfill is described. Also, data on the excavation of old waste in landfills and the condition in which the waste was found at different depths, as well as the conclusion on the behaviour of polymer waste.
