Sustainable development of waste tires recycling by functionalization

Celem projektu jest opracowanie technologii funkcjonalizowania rozdrobnionej gumy otrzymanej w wyniku dezintegracji zużytych opon samochodowych. Wytworzone funkcjonalizowane granulaty gumowe będą następnie wykorzystane jako modyfikatory kompozytów polimerowych i asfaltów drogowych. Funkcjonalizacja granulatów gumowych poprzez modyfikację ich powierzchni prowadzona będzie metodą wytłaczania reaktywnego, co pozwoli nadać nowe cechy użytkowe rozdrobnionym odpadom gumowym, w tym m.in. modyfikację ich przetwórstwa (nadanie cech materiałów termoplastycznych), wzrost stabilności termicznej czy kompatybilności z nową matrycą. W ramach projektu wykorzystane zostanie bogate doświadczenie Politechniki Gdańskiej i Uniwersytetu Jiao Tong w Szanghaju w dziedzinie recyklingu materiałowego zużytych opon samochodowych.

Cross-Linking, Morphology, and Physico-Mechanical Properties of GTR/SBS Blends: Dicumyl Peroxide vs. Sulfur System
Publication
- Materials - Year 2023
In this work, ground tire rubber and styrene–butadiene block copolymer (GTR/SBS) blends at the ratio of 50/50 wt%, with the application of four different SBS copolymer grades (linear and radial) and two types of cross-linking agent (a sulfur-based system and dicumyl peroxide), were prepared by melt compounding. The rheological and cross-linking behavior, physico-mechanical parameters (i.e., tensile properties, abrasion resistance,...

In this work, ground tire rubber (GTR) was thermo-mechanically treated in the presence of styrene-butadiene-styrene (SBS) copolymers. During preliminary investigation, the effects of different SBS copolymer grades, the variable content of SBS copolymer on the Mooney viscosity, and the thermal and mechanical properties of modified GTR were determined. Subsequently, GTR modified by SBS copolymer and cross-linking agents (sulfur-based...

The production of high-added value reclaimed rubber (RR) is of great signifi-cance for the sustainability of rubber industries. To green recycle waste rub-bers and broaden the application of RR, a RR material with potentialreinforcing and plasticizing effects on nature rubber (NR) composites are pre-pared by a thermo-oxidative reclamation process. The reclamation degree ofRR is controlled by adjusting the content of soybean oil....

- JOURNAL OF CLEANER PRODUCTION - Year 2022
Chemical modification of ground tyre rubber (GTR) to compatibilize it with the matrix is a well-known approach. Based on our recent review of the surface etching methods used in GTR modification, the purpose of the current work is to take a deeper look into more advanced methods such as grafting and reactive extrusion. While grafting is more efficient in achieving compatibility, however, it usually involves multi-step synthesis...

- SCIENCE OF THE TOTAL ENVIRONMENT - Year 2022
Waste tires management and further utilization are currently one of the biggest concerns regarding the environment and human health protection. At present, shredding, grinding, or pulverization of waste tires are the most popular options for industrial recycling. Although many solutions for ground tire rubber (GTR) applications were checked and verified so far, their further implementation at an industrial scale is still very limited....

- CONSTRUCTION AND BUILDING MATERIALS - Year 2022
Asphalt binder is generally identified as a brittle material at low service temperature or under high-speed load, and the brittleness becomes serious after weathering aging. Improving the toughness of asphalt binder through adding high-content of crumb tire rubber is an efficient method to solve this problem. Devulcanized rubber modified asphalt binder (DRMA) with different contents (15–40%) of devulcanized rubber (DR) were prepared...
