The numerous uses for plastics in various industries have led to an increase in its manufacturing on a global scale over time. The accumulation of plastic waste is a direct result of the daily rise in plastic demand. One of the effective and trending ways of reducing the impact of plastic waste on the environment is to pyrolyze it and use the oil obtained from it as fuel for power generation, heating, extraction of chemicals, or as an asphalt binder modifier. In this study, an attempt was made for the modification of asphalt binder with the oil obtained from plastic waste pyrolysis known as pyro-oil, and to analyse aging properties of the modified binder. This paper deals with the modification of VG30 binder with pyro-oil obtained from High Density Polyethylene (HDPE) plastic waste and the analysing the effect of aging on the modified binders. Pyro-oil is yielded from the pyrolysis process of HDPE at about 750°C. The modified binders were prepared by adding 1%, 2%, and 3% pyro-oil by total weight of VG30. The effect of aging for the unmodified and modified binders was analyzed using fourier transform infrared (FTIR) spectroscopy. The binders were short term aged and the changes in their chemical functionalities before and after aging were analyzed. Results of the FTIR test were used to calculate functional group indices for evaluating the aging characteristics of the modified binders. It was observed that binder chemistry is influenced by aging.

Rosnąca ilość zużytych tworzyw sztucznych stanowi na całym świecie istotny problem ekologiczny. Ze względu na brak podatności na hydrolizę, dekompozycję i degradację biologiczną utylizacja większości tworzyw sztucznych stanowi bardzo skomplikowaną problematykę. Destrukcja termiczna odpadów polimerowych jest jednym z perspektywicznych kierunków ich zagospodarowania. Otrzymane w wyniku pirolizy gazowe i ciekłe produkty węglowodorowe stanowią bardzo cenne surowce, które wykorzystywane są m.in. jako komponenty paliw. W niniejszej pracy przedstawiono różne techniki procesu pirolizy. Omówiono również warunki prowadzenia procesu oraz scharakteryzowano otrzymywane produkty. Z powodu obszernej tematyki dotyczącej degradacji odpadów tworzyw sztucznych, skupiono się tylko na procesach termicznych. Katalitycznym procesom rozkładu polimerów zostanie poświęcony kolejny artykuł.

The growing amount of plastics waste is an important environmental problems worldwide. Because most of plastics cannot undergo hydrolysis, decomposition and biological degradation their utilization presents a complicated problem. Thermal destruction of polymer waste is one of prospective ways of their utilization. Gas and liquid hydrocarbons obtained in this process are very valuable raw materials. One possibility is application as fuel components. Possible pyrolysis techniques were presented in this review. General composition of obtained products and process conditions were also reported. The decomposition process is a very extensive problem, so the main subject of our investigation was concentrated with thermal degradation of plastics wastes. The next paper will be devoted to catalytic degradation of polymer wastes.
