“…2,3 Therefore, the quest for economical and environment-friendly methods that allow potential application of waste tires in industry is very reasonable. [4][5][6] At present, one of the effective industrial-scale methods for recycling of used tires is the reclaiming/ devulcanization of ground tire rubber (GTR). During the devulcanization process, the three-dimensional network of cross-linked rubber is destroyed by means of thermal, mechanical or chemical energy.…”

Ground tire rubber from car and truck was modified using microwave irradiation at variable time. The irradiated ground tire rubber was used as filler in composites based on natural rubber. The composites, with high content of ground tire rubber, were prepared using an internal batch mixer and subsequently cross-linked at 160 C. The influence of the ground tire rubber source (car/truck) and irradiation time on structure, physico-mechanical behaviour, thermal properties and morphology of natural rubber/ground tire rubber composites was studied. The interfacial interactions between ground tire rubber and natural rubber as function of ground tire rubber source and irradiation time were evaluated by Fourier transform infrared spectroscopy, thermogravimetric analysis, tensile tests, swelling measurements and scanning electron microscopy. The results showed that irradiation of ground tire rubber slightly enhanced tensile properties and cross-link density of natural rubber/ground tire rubber composites. This effect was more evident in the case of ground tire rubber truck because of its higher content of natural rubber and was reflected in changes in the interfacial adhesion, which were confirmed by the results of Fourier transform infrared spectroscopy, thermogravimetric analysis and scanning electron microscopy analysis.

“…The use of crumb rubber in flexible polyurethane foams has a significant effect on the structure of the material, in which the density of cross-inking increases significantly. This increases the thermal stability of the material, where the decomposition temperature increased by 14 • C as compared with the sample without crumb rubber [77].…”

Despite technological developments, modern methods for the disposal of end-of-life tires most often involve either their incineration in cement kilns or the destruction of tires in special landfills, demonstrating a lack of sustainable recycling of this valuable material. The fundamental role of recycling is evident, and the development of high-efficiency processes represents a crucial priority for the European market. Therefore, the investigation of end-of-life rubber processing methods is of high importance for both manufacturers and recyclers of rubber materials. In this paper, we review existing methods for processing of end-of-life tires, in order to obtain rubber crumb, which can later be used in the production of new industrial rubber goods and composites. We consider processes for separating end-of-life tires into fractions (in terms of types of materials) using chemical, mechanochemical, and mechanical methods to process the materials of used tires, in order to obtain crumb rubber of various fractions and chemical reactivities.

“…It is ascribed to the poor adhesion between untreated rubber and PU matrix. Piszczyk et al [70] also investigated the modification of PU foams by two kinds of GTR, untreated and thermo-mechanically reclaimed with the exception that the whole process were carried out using a co-rotating twin screw extruder. It was proven that usage of GTR as a filler in PU foams leads to improvement of the thermal stability and compressive strength.…”

Abstract. Diversity of the polyurethane (PU) foams applications cause that investigation of the relationships between their structure and properties is currently very popular topic among the many research institutions and companies. At the turn of the last years many scientific papers about PU foams and their composites were published. The one of the main research trends in this field is related to the reduction of production costs of PU foams. This aim can be successfully achieved through the incorporation of raw materials of natural origin or the utilization of waste materials. This work reviews the progress and recent developments in area of PU foams containing low-cost and pro-ecological modifiers, such as crude glycerol, liquefied biomass, ground tire rubber, etc.
