    Mining tyres, exceeding 4 m in diameter with operational lifespans of approximately seven months, present significant environmental and operational challenges through considerable waste accumulation. While substantial research addresses conventional tyre recycling, end-of-life mining tyres (ELMTs) require specialised management strategies due to their unique composition and operational constraints. This study develops a decision framework to assess and prioritise ELMT management solutions within Chile's mining sector, the world's leading copper producer. The hybrid methodology integrates Rogers’ Technology Adoption Model with Fuzzy Analytic Hierarchy Process (FAHP) and Fuzzy Technique for Order Preference by Similarity to Ideal Solution (FTOPSIS), utilising data from 17 mining industry experts. Results indicate that while pyrolysis demonstrates the highest adoption potential, retreading and shredding exhibit superior environmental performance. This choice is primarily driven by compatibility considerations, particularly operational safety and continuity, constituting approximately 52% of selection criterion weight. The findings highlight a critical trade-off between ecological benefits and operational dependability in mining environments, providing valuable insights for mining companies implementing circular economy practices, recycling technology suppliers and policymakers developing targeted mining waste management regulations.
