The recycling process is an important step in waste management for a sustainable environment. However, some steps in the recycling process may pose a risk to human health. Oxides that remain in the open area for a long time due to the inability to storage threaten the environment and toxic wastes may spread to the environment due to human or software-related errors that may occur on machines. Therefore, system reliability is essential for the correct operation in recycling facilities. In this study, interval type-2 fuzzy numbers are evaluated for system reliability of recycling facilities. Using the performance and reliability indexes created with fuzzy expressions, the reliability level of the system and priority problems affecting system reliability are identified.
