“…The largest problem all plant engineers and researchers are facing is that the dispersion of CBp in rubber matrix is poor and the uncounted agglomeration of it is obvious. At the same time, the interaction among CBp in rubber blend is quite strong (Li et al, 2016).…”

Pyrolysis offers a more focused alternative to waste tyres treatment. Pyrolytic carbon black (CBp), the main product of waste tyre pyrolysis, and its modified species can be applied to tyre manufacturing realizing its high-value utilization. Modified pyrolytic carbon black/natural rubber composites prepared by a wet compounding (WC) and latex mixing process have become an innovative technology route for waste tyre remanufacturing. The main properties and applications of CBp reported in recent years are reviewed, and the main difficulties affecting its participation in tyre recycling are pointed out. The research progress of using WC technology to replace dry mixing manufacturing of new tyres is summarized. Through literature data and comparative studies, this paper points out that the characteristic of high ash content can be well utilized if CBp is applied to tyre manufacturing. This mini-review proposes a new method for high-value utilization of CBp. The composite mixing of CBp and carbon nano-materials under wet conditions is conducive to the realization of their good dispersion in the rubber matrix. This provides a new idea for customer resource integration and connection of industry development between the tyre production industry and waste tyre disposal management.

“…Several lab approaches have prepared PCB from waste tires in the literature, TGA pyrolysis, 6 melt-extrusion pyrolysis, 7,8 and bed reactor pyrolysis. 9 Regenerated carbon black was found to have a higher surface area, elongation at break, and heat buildup, but a lower curing speed, modulus, and a comparable state of cure, dispersion, hardness, tensile strength, and tear strength compared with those of the virgin carbon black.…”

Only a few works focus on the use of commercial pyrolysis carbon black (PCB) to replace with commodity carbon black in terms of increasing environmental awareness. In this work, a commercial PCB (ET (Enrestec) black) from waste tires was compared with N660 carbon black in styrene–butadiene rubber (SBR) compounds using standard American Society for Testing and Materials recipes. Particle aggregate size, composition, and surface functionality of ET black and N660 were analyzed through light scattering, energy-dispersive X-ray spectroscopy (EDS), and Fourier transform infrared spectroscopy, respectively. Higher compound viscosity and aggregation power for ET black filler in the rubber matrix was observed. A progressive decrement of approximately 20% in M300 from 15.2 MPa for N660-filled SBR to 12.4 MPa for ET black-filled SBR with increasing ET black ratio in the fillers was clearly observed. ET black could potentially replace 20% in N660 without much influence for SBR compounds in terms of tensile strength. The effect of ET black content on the tear strength was less marginal than the tensile strength. However, with increasing the ET black content, the abrasion resistance index progressively decreased. Thus, it was quite beneficial to consider the merit of PCB in terms of the applications required for tearing resistance. This paves the way for the opportunities to expand further commercial application of PCB from waste tires in the light of environmental awareness.

“…At present, the disposal methods of waste tyre rubbers include landfill, retreading, gasification, incineration and pyrolysis (Duan et al, 2015; Li et al, 2016; Undri et al, 2013a). As a typical circular economy mode, the pyrolysis is an economical and environmentally friendly method, which recovers the economical products from waste tyres, such as pyrolysis oil, pyrolysis gas and solid coke, through a pyrolysis process (Williams, 2013).…”

“…Therefore, the pyrolytic CB of the waste tyres is often a mixture of various kinds of CBs, and their structures and size distributions do not obey the Gaussian distribution as those commercial CBs do. Compared with commercial CBs, pyrolytic CB has defects, such as high ash contents, poor surface activity and easy nodulising (Antoniou and Zabaniotou, 2015; Li et al, 2016; Williams, 2013). Among these, the high content of ash, that is the low effective CB content, is adverse to the rubber reinforcement of applied CB, and the ash will cover the active sites on the surface of CB, reducing the surface activity of CB.…”

The medium temperature pyrolysis process using a fixed-bed reactor at atmospheric pressure was utilised to recover carbon black from motorcycle and automobile tyres. Experimental results have shown that the ash and volatile contents of several recovered carbon blacks are high, the elongation at break of the vulcanised natural rubber filled with recovered carbon blacks from motorcycle tyres is better than that from motorcycle tyres and standard carbon black 7#, while the other mechanical properties are worse. In order to improve the reinforcing effect of recovered carbon blacks, the modification of recovered carbon black was performed by high-energy electron bombardment and non-oxidising acid. The specific surface area of the pyrolytic carbon blacks increased after high-energy electron bombardment. The ash content of the pyrolytic carbon black was reduced from 22.5% to 8.4% after rinsing with hydrochloric acid, and the tensile stress at 300% was increased by about 2.2 MPa.
