AbstractThe end-of-life tyres (ELTs) are currently critical environmental and societal problems due to their large quantity and chemical structure. The thermochemical process has been acknowledged as a viable option for extracting material and energy from ELTs. This review outlines the cutting-edge thermochemical techniques for recycling tyres, encompassing gasification, pyrolysis, and incineration. Additionally, it delves into the primary by-products, including oil, gas, and char. The advantages and disadvantages of each process are discussed in terms of energy efficiency, product yield, and environmental impact. The optimal reaction conditions for each product yield and quality are identified and described. The correlation between process parameters and product composition, yield and quality is clarified. Products after further processing are illustrated with specific examples. Future research directions such as upgrade of char product using low-temperature partial-oxidation process are given. This review is novel in its comprehensive synthesis of the latest advancements in thermochemical techniques for recycling ELTs, highlighting recent innovations in gasification, pyrolysis, and incineration methods. It is also a timely review due to the urgent need for sustainable waste management solutions amidst growing environmental concerns and stringent regulations on tyre disposal. Graphical Abstract
