waste tires

The review considers the environmental problem of generation, accumulation and utilization of waste tires in Ukraine and the world. It is established that waste tires can serve as a valuable raw material for obtaining fuel components and technical/individual chemicals for further industrial processing. One of the promising methods for the rational utilization of waste tires may be their pyrolysis. The pyrolysis process of waste tires produces gaseous, liquid and solid carbonized residue.

The paper analyzes the possibility of utilizing the solid carbonized residue (SCR) from the pyrolysis of waste tires (WT). The pyrolysis process of waste tires produces about 36% of carbonized residue, which can serve as an adhesive and/or modifying additive in the processes of modifying petroleum bitumen. We analyzed the SCP and BND 70/100 bitumen produced at a small-scale industrial unit and PJSC Ukrtatnafta, respectively. The influence of solid carbonized residue on the performance properties of modified bitumen at different ratios of raw materials (BND 70/100) : SCR.
