Background: Solid waste management is one of the important aspects of the hospital management.
Methods: In this study, 8 privative hospitals in Tehran were studied on the quantity and composition of medical solid waste. For this purpose, a checklist was used through interviews with hospital waste management staff as well as hospital waste generation information. The annual average of obtained data were analyzed.
Results: The results showed that in the studied privative hospitals the generation of solid waste were 24 to 1091 kg/day. The average medical waste generation in the studied privative hospitals was 4 kg/bed/day equal to 5.09 kg/patient/day. Common waste accounted for 70.73% of total hospital solid waste, while infectious and sharp waste accounted for 31.04% of the hospital solid waste. Infectious wastes were disinfected using autoclave in all hospitals.
Conclusion: Segregation of infectious waste from hospital waste mass reduces the environmental and health risk of hospital waste and reduces the cost of waste management in private hospitals.
