The production of waste tires is steadily increasing, leading to challenges like slow degradation, severe environmental pollution, and significant land use. To address these issues, waste tire valorization has emerged as a crucial aspect of global environmental protection and sustainable development, garnering widespread attention and promotion. Innovative technologies are being leveraged to convert waste tires into valuable products and energy, promoting resource recycling and mitigating environmental harm. While existing literature has highlighted key technologies in the waste tire valorization process, this study aims to comprehensively review the current advancements in waste tire valorization from various angles, including processes, optimization, and evaluation, to support its sustainable development. Firstly, it outlines advanced technologies in the waste tire valorization process for producing value-added products, such as grinding, pyrolysis, and critical devulcanization stages. Secondly, it summarizes simulation and optimization techniques applied in waste tire valorization. Lastly, it discusses the application of sustainable assessment methods like techno-economic assessment, Life Cycle Assessment (LCA), and Sustainable Development Goals (SDGs) in waste tire valorization, proposing the establishment of a unified assessment system. The review findings suggest that (1) developing a super-structural waste tire valorization framework offers a promising path for technological enhancement and low-carbon sustainable transformation. (2) Integrating mechanism and data-driven method in simulation modeling enhances result accuracy and interpretability. (3) Creating a multi-objective optimization model to optimize waste tire valorization from economic, technological, social, and environmental perspectives can drive efficient and low-carbon development. (4) Establishing a unified sustainability assessment system will standardize the evaluation of waste tire valorization's sustainability.
废旧轮胎的产量正在稳步增加，带来了诸如降解缓慢、严重环境污染和大量土地占用等挑战。为解决这些问题，废旧轮胎资源化已成为全球环境保护和可持续发展的关键方面，受到广泛关注和推广。人们正在利用创新技术将废旧轮胎转化为有价值的产品和能源，促进资源回收利用并减轻环境危害。虽然现有文献已经强调了废旧轮胎资源化过程中的关键技术，但本研究旨在从包括工艺、优化和评估等多个角度全面回顾废旧轮胎资源化的当前进展，以支持其可持续发展。首先，它概述了废旧轮胎资源化过程中用于生产增值产品的先进技术，如研磨、热解和关键脱硫阶段。其次，它总结了应用于废旧轮胎资源化的模拟和优化技术。最后，它讨论了技术经济评估、生命周期评估（LCA）和可持续发展目标（SDGs）等可持续评估方法在废旧轮胎资源化中的应用，提出建立统一的评估体系。综述结果表明：（1）开发一个超结构废旧轮胎资源化框架为技术提升和低碳可持续转型提供了一条有前景的途径。（2）在模拟建模中整合机理和数据驱动方法可提高结果的准确性和可解释性。（3）创建一个多目标优化模型，从经济、技术、社会和环境角度优化废旧轮胎资源化，可推动高效和低碳发展。（4）建立统一的可持续性评估体系将规范对废旧轮胎资源化可持续性的评估。
