End-of-life vehicles (ELV) represent a relevant waste source in Europe, even if ELV recycling is a priority of the European Union waste legislation and Environment Action Programmes (EAPs). End-of-Life Tires (ELTs) constitute a relevant portion of ELV waste. Textile fibre, which is a relevant portion of the ELT material, is considered as a special waste (European Waste Catalogue – EWC code 19.12.08). The main problem related to textile fibre is its contamination with rubber which does not allow to obtain a pure product economically and qualitatively useable.

The aim of this paper is to illustrate an innovative technology for ELT fibre's recycling, which allows to transform textile fibre into a useful secondary raw material for different applications.

In particular, the use of ELT fibre as additive for bituminous conglomerates has been investigated. The different processes have been analysed from an environmental point of view, applying the Life Cycle Assessment methodology. It came up there is an impact reduction in case the ELT fibre is reused as additive for bituminous conglomerates, instead of disposing it (through incineration).

Moreover, the financial and economic sustainability of the related technological process has been evaluated to check whether the process is sustainable in the long term. Starting from the results of the Life Cycle Assessment, economic performance indicators have been calculated, by applying the European Commission methodology for cost-benefit analysis. According to the present cost-benefit analysis, in the medium and long term the system is financially viable, and the high economic profitability makes the process economically sustainable. Furthermore, a sensitivity analysis as well as a risk assessment have been carried out in order to identify critical variables, evaluate risks and define risk mitigation measures. According to the sensitivity analysis performed, the project is not highly risky since even in the worst scenario the possible loss is moderate.

Based on the results of this analysis, it can be concluded that this ELT fibre's recycling system can be replicated across Europe, conveniently fostered by national policies (such as subsidies, value added tax etc.).

报废车辆（ELV）代表了欧洲的相关废物源，即使ELV回收是欧盟废物立法和环境行动计划（EAP）的优先事项。报废轮胎（ELT）构成ELV废物的相关部分。纺织品纤维是ELT材料的重要组成部分，被视为特殊废物（欧洲废物目录– EWC代码19.12.08）。与纺织纤维有关的主要问题是其被橡胶污染，这使得不能经济地和定性地获得纯净的产品。

本文的目的是说明用于ELT纤维回收的创新技术，该技术可以将纺织纤维转变成适用于不同应用的有用的二次原料。

特别地，已经研究了使用ELT纤维作为沥青团块的添加剂。从生命周期的角度分析了不同的过程，并应用了生命周期评估方法。如果将ELT纤维重新用作沥青团块的添加剂，而不是将其处置（通过焚化），则会降低冲击力。

此外，已经评估了相关技术过程的财务和经济可持续性，以检查该过程在长期内是否可持续。从生命周期评估的结果开始，通过将欧洲委员会的方法应用于成本效益分析，计算了经济绩效指标。根据目前的成本效益分析，从中长期来看，该系统在财务上是可行的，并且较高的经济获利能力使该过程在经济上可持续。此外，已经进行了敏感性分析和风险评估，以识别关键变量，评估风险并定义风险缓解措施。根据执行的灵敏度分析，

根据分析结果，可以得出结论，这种ELT纤维的回收系统可以在欧洲复制，可以通过国家政策（如补贴，增值税等）方便地进行推广。
