“…Recently, Shi et al [9] conducted reclaiming of GTR using a corotating twin screw extruder at 250 C and 300 C. It was observed that above 200 C the thermal degradation of ground tire rubber increases and thus increases its degree of reclaiming. Authors presented thermogravimetric measurements, which suggest that reclaiming of ground tire rubber conducted at 300 C corresponds with release of about 7% wt.…”

“…This indicates that light pyrolysis can be categorized as a method combining reclaiming and pyrolysis processes. This allows production of new group of waste tires recycling products, which could found application as bitumen modifiers [92], semi-reinforcing fillers [93] or reactive plasticizers [94,95]. Gasification is another interesting approach which should advance the application of microwave-assisted thermal decomposition in near future.…”

Environmentally-friendly microwave heating is increasingly used in polymer chemistry and technology. The selectivity and highly efficiency in the heat transfer present a huge advantage in systems based on recycling, improving their productivity and economic competitiveness. In case of the industrial recycling of waste rubbers, especially end-of-life tires, microwave-induced devulcanization and pyrolysis are nowadays considered as promising approaches. This work aims to report the recent progress in microwave treatments of vulcanized rubbers with different compositions. Special attention is focused on the correlation between microwave processing parameters and devulcanization/pyrolysis efficiency, which have a significant impact on the structure-property relationships of the obtained products. Moreover, the main challenges affecting the future of the industrial application of the microwave technology in rubber recycling are also discussed.

“…The investigation on the durability of waste rubber, especially ground tire rubber, can be explored in some previous reports. The thermal analyses of the reclaimed tire rubber waste without mixing with virgin rubber have been investigated by some researchers [83][84][85]. In the investigation, the method for compounding crumb rubber utilizes screw mixer in the temperature of 180 C with additional vulcanization agents such as zinc, sulfur, and stearic acid.…”

“…Recycling process of tire rubber has been reported in another article, in which the so-called tire reclamation is preferable to disposal storage options due to the harmful e ect on soils and underground water [16]. The reclamation of tire rubber is typically conducted by shredding it into powder form (with 2-3 mm of diameter) through either cryogenic or room temperature grindings.…”

Abstract. This study reports a reclamation method of Ground Tire Rubber (GTR) and electronic wastes into a tunable sti ness composite, namely magnetorheological elastomers (MREs). The composite matrix was the GTR that had been separated from its metals and yarns. Meanwhile, the llers were fabricated from magnetic cores of the Cathode Ray Tubes (CRTs) monitor waste through high energy ball milling in wet condition. Some physicochemical characterizations of the powders were initially conducted to collect the physical and chemical properties. Based on the examination, the ground powders were identi ed as pure magnetite (Fe 3 O 4 ) having low remnant and high magnetization. The MREs samples were prepared by high-temperature high-pressure sintering. The mixed of crumb rubber and magnetite powder was vulcanized under simultaneous pressure and temperature in the absence of magnetic elds, which resulted in an isotropic MREs type. The abilities of specimens were examined in relation to the external magnetic eld through static and dynamic compression tests. The experimental investigation showed that the static and dynamic stresses of the sti ness increased by the increment of magnetic elds up to a particular point of ux density. The tunability of the sti ness indicated that the elastomers could provide wide ranges of storage and loss modulus.
