Environmental and social awareness are the key elements of the sustainable tire industry. End-of-life tire (ELT) waste flow is an important environmental problem worldwide since it produces severe air, water, and soil pollution issues. Significant advancements have been made in ELT management in the last few years. As a result, ELTs should not only be regarded as waste but also as a source of environmentally friendly materials. Besides, sound ELT management has vital importance for circular economy and sustainable development. Over the last decade, ELT management has attracted many researchers and practitioners. Unfortunately, a comprehensive review of the ELT management area is still missing. This study presents the first critical review of the whole ELT management area. It aims to present an extensive content analysis overview of state-of-the-art research, provide its critical analysis, highlight major gaps, and propose the most significant research directions. A total of 151 peer-reviewed studies published in the journals between 2010–2020 are collected, analyzed, categorized, and critically reviewed. This review study redounds comprehensive insights, a valuable source of references, and major opportunities for researchers and practitioners interested in not only ELT material flow but also the whole waste management area.

“…Cherbański et al observed that three characteristic steps can be distinguished from of the waste tire pyrolysis. These steps correspond to the evaporation and thermal decomposition of 1) oil, plasticizer, additives, and moisture in the first step, 2) natural rubber in the second step, and 3) styrene-butadiene rubber in the third step [60]. As a comparison, the analysis results from the inner liner using the same method show that Reaction A conforms to the threedimensional diffusion mechanism.…”

The disposal of used automobile tires is a major waste concern. Simply stacking tires and allowing them to decompose will harbor breeding mosquitoes that spread viruses, whereas burning them will release acidic and toxic gases. Therefore, one viable option is pyrolysis, where elevated temperatures are used to facilitate the decomposition of a material. However, the lack of theoretical support for pyrolysis technology limits the development of the pyrolysis industry when it comes to discarded tires. The purpose of this research is to put forward a brand-new multi-kinetic research method for studying materials with complex components through the discussion of various kinetic research methods. The characteristic of this kinetic research method is that it is a relatively complete theoretical system and can accurately calculate the three kinetic factors considered during the pyrolysis of multicomponent materials. The results show that the multi-kinetic research method can obtain the kinetic equation and reaction mechanism for the pyrolysis of tires with high accuracy. The pyrolysis process of this compound was divided into two stages, Reaction I and II, where the kinetic equation of Reaction I was f ( α ) = 0.2473 α − 3.0473 , with an activation energy of 155.26 kJ/mol and a pre-exponential factor of 5.88 × 109/min. Meanwhile, the kinetic equation of Reaction II was f ( α ) = 0.4142 ( 1 − α ) [ − ln ( 1 − α ) ] − 1.4143 , while its activation energy was 315.40 kJ/mol and its pre-exponential factor was 7.86 × 1017/min. Furthermore, based on the results of the research analysis, the reaction principles corresponding to Reaction I and Reaction II in the pyrolysis process of this compound were established.

“…The overall decomposition and stability of waste tyre pyrolysis include the pre-exponential factor and the order of the reaction. Furthermore, Cherbanśki et al 146 revealed three steps of waste tyre pyrolysis process: evaporation and thermal decomposition of (1) oil, plasticiser, and moisture in the first step, (2) natural rubber in the second step, and (3) styrene− butadiene rubber in the third step. The constant energy input activates a significant extent of pyrolysis reactions of waste tyre when the temperature rises from 180 to 400 °C.…”

This paper first reviews the serious environmental concerns and waste management due to the rapid increase in the vast quantity of waste tyre globally. It then articulates the importance of pyrolysis as an attractive technical route for valorising waste tyre. A systematic summarisation on pyrolysis reaction chemistry is presented, including those for both waste tyre and its individual components. The key factors, including feedstock properties, reactor configurations, and reaction conditions that influence the properties and distribution of pyrolysis products and transformation and fate of impurities, are discussed. Such knowledge is essential to selecting operating parameters for optimal pyrolysis products and process performance. Potential applications of waste tyre pyrolysis products (i.e., char, oil, and gas) are subsequently surveyed and summarised. The important roles of key impurities (especially sulfur) and their derivatives, which are major constraints for commercialisation of waste tyre pyrolysis technologies, are also discussed. Remediation strategies of these impurities in pyrolysis products are summarised, compared, and benchmarked. The recent progress in process development, techno-economic analysis, and life cycle analysis of waste tyre pyrolysis processes is also covered. In closing, the remaining challenges and research gaps in the field of waste tyre pyrolysis are identified and future research perspectives are outlined.
