The aim of this research is to analyse the performance of the extended producer responsibility model for the management of end-of-life tires (ELTs) in Ecuador that has been implemented since 2013. For this research, we conducted case studies of, and subsequently, a comparative analysis between, the ELT management system in Ecuador with respect to the ELT management models in Colombia and Brazil. Our findings show that although the programme implementation represented a significant advance in Ecuador’s waste management system there are important challenges that should be considered in future adaptations of the programme. Among the measures that can be adopted to improve the ELT management system are the consolidation and stimulation of the market for products made from ELT waste; promotion of other productive sectors linked to the creation of new products and sectors that generate complementary products; enhancement of the generation, socialization and access to knowledge of the waste by-products for micro-, small- and medium-sized enterprises; increase the tire consumer fee, known as ‘Ecovalor’ and improvement of the quality and availability of information and indicators regarding ELT management. In this sense, the experiences of Colombia and Brazil show important lessons for the Ecuadorian case.

报废轮胎的生态管理：厄瓜多尔案例的进展和挑战

本研究的目的是分析厄瓜多尔自 2013 年以来实施的用于管理报废轮胎 (ELT) 的生产者延伸责任模型的绩效。在本研究中，我们进行了案例研究，随后厄瓜多尔的 ELT 管理体系与哥伦比亚和巴西的 ELT 管理模式的比较分析。我们的研究结果表明，尽管该计划的实施代表了厄瓜多尔废物管理系统的重大进步，但在未来调整该计划时应考虑一些重要的挑战。改善ELT管理体系可采取的措施包括巩固和刺激ELT废物制成的产品的市场；促进与创造新产品和产生互补产品的部门相关的其他生产部门；加强微型、小型和中型企业废物副产品的产生、社会化和知识获取；提高轮胎消费者费用（称为“Ecovalor”），并提高有关 ELT 管理的信息和指标的质量和可用性。从这个意义上说，哥伦比亚和巴西的经验为厄瓜多尔的案例提供了重要的教训。
