The disposal of automotive waste tires is an increasing environmental problem worldwide. The recycling of waste tire is challenging because tires are produced by chemical cross-linking of polymer-filler materials. Among the diverse disposal methods available for waste tires disposal, pyrolysis is considered as a promising recycling approach. The pyrolysis method presents the possibility of transforming hundreds of tons waste tires into gaseous, liquid, and carbon-rich solid (RCB) fractions, mainly contains carbon fractions from conventional carbon black (CB) and inorganic ingredients used during tire building. Owing to numerous environmental concerns with the production and utilization of conventional CBs, a broad consensus among the industrialist is to replace CBs with equally effective material. RCB has the potential to replace the conventional CB in polymer matrix solving dual pollution problems. In this work, the RCB obtained from batch pyrolysis was investigated by Fourier transform infrared spectroscopy, scanning electron microscopy, and X-ray diffraction. The surface area of RCB estimated by the BET method, the DBP oil absorption test, was carried out to understand the structure of RCB. Although RCB exhibited low structure, the surface functional group found to contain acidic based complex material. Lastly, RCB was used in Natural rubber-based rubber compounds of general-purpose conveyor belts to investigate its practical feasibility as a substitute for commercial-grade N330 CB. Mechanical properties of the RCB reinforced composites found to be lower than the conventional CB loaded composites. However, limitations can be overcome by using a combination of RCB with conventional CB to obtain the optimal balance of reinforcement and targeted properties.

汽车废轮胎的处置是世界范围内日益严重的环境问题。废轮胎的回收具有挑战性，因为轮胎是通过聚合物填充材料的化学交联生产的。在可用于废轮胎处理的多种处理方法中，热解被认为是一种有前途的回收方法。热解方法提供了将数百吨废轮胎转化为气态，液态和富碳固体（RCB）馏分的可能性，其中主要包含常规炭黑（CB）的碳馏分和轮胎制造过程中使用的无机成分。由于在生产和使用常规CB时存在许多环境问题，因此工业家之间的广泛共识是用同样有效的材料代替CB。RCB有潜力替代聚合物基质中的常规CB，从而解决双重污染问题。在这项工作中，通过傅立叶变换红外光谱，扫描电子显微镜和X射线衍射研究了从间歇热解获得的RCB。通过BET法（DBP吸油测试）估算了RCB的表面积，以了解RCB的结构。尽管RCB显示低结构，但发现表面官能团包含酸性基复合材料。最后，RCB用于通用型输送带的天然橡胶基橡胶混合物中，以研究其替代商业级N330 CB的实际可行性。发现RCB增强复合材料的机械性能低于传统的CB负载复合材料。然而，
