THE USAGE OF RUBBER POWDER OBTAINED FROM WATERJET TECHNOLOGIES IN TYRE COMPOUND PRODUCTION
 
The worldwide growth in the use of passenger cars, motorbikes, bikes, busses and trucks required the production of a huge amount of tyres that, at the end of their useful life, became a huge amount of wastes to be disposed. The sales of new tyres in Europe during the year 2020 accounted for 324 million units, 89.5% for passenger cars and light duty vehicles, 4.9% for heavy duty vehicles (trucks and busses), 3.6% for motorbikes and scooters and 1.9% for agricultural and off-the-road vehicles. The recycling and disposal of end-of-life tyres (ELTs) are major challenges in the reduction of the environmental pollution process due to their complex composition. As the disposal of waste rubber becomes a worldwide problem, the reuse of tire components has also gained importance. The aim of this study is to investigate the potential for the reuse of ELRs in the same sector to reduce the carbon footprint of tyres. The use of powdered rubber shredded from ELTs (TyreXol™ TW50) with a surface area of 0.10-0.12 m2/g by using waterjet technologies on motorcycle tread tyres was investigated. The rheological and physico-mechanical properties of rubbers developed using 16.3 phr (Parts Per Hundred Rubber) TyreXol™ TW50 showed good performance. The findings from this study promise an innovative way to reduce pollution caused by ELTs. ORCID NO: 0000-0002-8716-4520
