Abstract The increasing concern for sustainability and longing for the transition into the circular economy has fostered an immense interest in re-configuring the end-of-life tyre supply networks. However, the existing literature is incapable of providing sufficient guidance in regard to the allocation of end-of-life tyre among recycling outlets to maximise the circular economy and sustainability outcomes. Hence, this study aims to propose a comprehensive list of evaluation criteria to rank recycling outlets, and develop an end-of-life tyre outlets selection matrix. A hybrid method is proposed by integrating fuzzy Analytical Hierarchy Process, fuzzy Technique of Order Preference Similarity to the Ideal Solution, the multi-objective linear programming, and semi-structured interviews. By analysing the empirical data collected from one of the largest European collectors, this study reveals that cement manufacturing, which is the primary recycling outlet, ranks the lowest among the five recycling outlets in terms of the circular economy and sustainability outcome. Nevertheless, synthetic turf manufacturing and moulded objects manufacturing rank the highest in the circular economy and sustainability outcomes, respectively. It is proved that cost and profit are key drivers for recycling outlets selection, subjected to end consumers’ perceptions and the ease of end-of-life tyre processing. The ranking and the performance of recycling outlets also signify the competitive relationship between the circular economy and sustainability as excelling in the circular economy outcome would trade-off sustainability performance.

最大化循环经济和可持续性成果:报废轮胎回收网点选择模型

摘要 对可持续性的日益关注和向循环经济转型的渴望激发了对重新配置报废轮胎供应网络的极大兴趣。然而,现有文献无法就报废轮胎在回收渠道之间的分配提供足够的指导,以最大限度地提高循环经济和可持续性成果。因此,本研究旨在提出一份综合评估标准清单,以对回收网点进行排名,并制定报废轮胎网点选择矩阵。提出了一种综合模糊层次分析法、与理想解的顺序偏好相似性模糊技术、多目标线性规划和半结构化访谈的混合方法。通过分析从欧洲最大的收集商之一收集的实证数据,该研究表明,水泥制造是主要的回收渠道,在循环经济和可持续性成果方面,在五个回收渠道中排名最低。尽管如此,合成草皮制造和模塑制品制造分别在循环经济和可持续性成果中排名最高。事实证明,成本和利润是回收网点选择的关键驱动因素,受最终消费者的看法和报废轮胎处理的难易程度的影响。回收网点的排名和表现也表明循环经济与可持续发展之间的竞争关系,因为在循环经济结果中表现出色会权衡可持续发展表现。
