Abstract

Background: Medical waste is one of the health and environmental challenges in the world. Hospitals are one of the most important medical waste generators.
Methods: In this study, the quantity and composition of solid waste generated in 10 public hospitals in Tehran were investigated. Medical waste was classified into four groups and the one-year average was considered.
Results: The results showed that the range of waste generation in public hospitals is 107.5 to 2508 kg/day. Considering account hospital beds, the production of medical waste in public hospitals averaged 3.53 kg/bed/day. 67.45% of medical waste in the studied hospitals included common waste, but infectious and sharp waste accounted for 31.65% of the medical waste. Chemical and pharmacy wastes accounted for an average of 0.8% of the medical wastes.
Conclusion: Due to the importance of medical waste management, it is necessary to pay more attention to segregation and reduce the proportion of infectious waste in the studied hospital.
