Survey of quantity and management condition of end-of-life tires in Iran: a case study in Tabriz
Once a tire is removed from a vehicle without the possibility of being remounted for continued on-road use, it is defined as waste and called end-of-life tire (ELT). ELTs are non-biodegradable, cannot be compressed and occupy large amount of space in landfills. Dumped tires provide breeding grounds for vectors and rodents and are susceptible to fire hazards. Numerous actions have been taken to manage ELTs worldwide; however, in Iran, there has not been much attention given to the issue. The goal of this study was to survey quantity and management conditions of ELTs and present managing principles according to the environmental and health aspects in Iran (a case study in Tabriz). The amount of ELTs in Iran was estimated by considering the production, import, export and life of tires. Next the current ELT management condition in Tabriz City was investigated using a checklist, observation, site visiting and interview. Then by considering scientific sources and also, according to experiences in other countries and current conditions, managing principles were suggested. Results showed that 198,346–339,678 tonnes of ELTs have been produced in Iran during 2003–2015 that equals 2.95–4.52 kg per capita per year. The amount of ELTs has had almost increasing trend during last 13 years. About 6390 tonnes of ELTs annually in Tabriz City are landfilled or dumped, which can create great hazards to the health and environment. Based on the results of this study, for improving the current condition of ELTs, first, the ELT production must be reduced and then ELTs must be reused or recycled. Moreover, landfilling of ELTs should be banned gradually and extended producer responsibility (EPR) system must be implemented for their management.
