The development of health services of hospitals in developing countries has led to a significant increase in the production of infectious waste, which has important economic and environmental consequences. Therefore, reducing pollutant leakage caused by disinfection and reducing infectious waste management costs are important in achieving sustainable development goals in hospital management. In this study, the centralized and decentralized patterns of infectious waste management were studied in three hospitals in Behbahan, Iran. Economic analysis was done based on the financial model. Phthalate emission from disinfection equipment was measured for investigating the level of exposure to the pollutant in the studied patterns. The results showed that the cost of waste transportation for studied hospitals in the centralized patterns increased by 12.1 %. However, reductions in disinfection and transfer costs up to 32.4 % were available by increasing the segregation ratio of infectious waste. The average emission of phthalates from disinfection equipment in the studied hospitals was 0.260 ng/kg. But emission of phthalate types was not the same, so that the emission of BEHP, IBP, and DBP was 35.97, 4.90, and 1.55 μg/m, respectively. Considering the hospital waste reduction plan and increasing the segregation ratio to reduce the costs of the hospital led to economic justification of the centralized pattern of infectious waste management as a safe option.
发展中国家医院卫生服务的发展导致传染性废物产量大幅增加，这产生了重要的经济和环境后果。因此，减少消毒引起的污染物泄漏以及降低传染性废物管理成本对于实现医院管理的可持续发展目标至关重要。在本研究中，对伊朗贝赫巴汉的三家医院的传染性废物管理集中式和分散式模式进行了研究。基于财务模型进行了经济分析。测量了消毒设备中的邻苯二甲酸酯排放量，以调查所研究模式下污染物的暴露水平。结果表明，集中式模式下所研究医院的废物运输成本增加了12.1%。然而，通过提高传染性废物的分类比例，消毒和转移成本可降低32.4%。所研究医院消毒设备中邻苯二甲酸酯的平均排放量为0.260 ng/kg。但邻苯二甲酸酯类型的排放量并不相同，其中BEHP、IBP和DBP的排放量分别为35.97、4.90和1.55 μg/m。考虑到医院废物减少计划并提高分类比例以降低医院成本，使得传染性废物管理集中式模式作为一种安全选择具有经济合理性。
