In the study, a multi-purpose reverse logistics network has been designed to create effectual management of medical waste (MW) generated in 39 districts of Istanbul, a heavily populated city, during the COVID-19 pandemic as well as that to be generated in the next decade. With the model, the medical waste management system in Istanbul is analyzed during the pandemic and for the next 10 years. The model attempts to integrate economic, environmental, and social objectives within the sustainable development goals. It aims to maximize the number of personnel and government earnings for the estimated MW of a megacity while minimizing the total fixed cost and the cost of carbon emissions and transportation. The results indicated that the existing facilities are sufficient for the treatment and disposal of MW generated even under pandemic conditions. However, the capacity of the sterilization facility could be insufficient to treat the estimated amount of MW in the next decade. Opening a sterilization facility near the sanitary landfill in Komurcuoda with a total management cost of 62,450,332 €/year would be an optimum solution for Istanbul MW. In comparison to the single-purpose model results, the multi-purpose model resulted in approximately 42,000 € more in total cost. Sensitivity analyses show that the amount of MW has the most significant effect on the total cost. This simple model created an effective MW management proposal for Istanbul, which can be a model for megacities.

在本研究中，设计了一个多用途逆向物流网络，以有效管理在新冠疫情期间伊斯坦布尔（一个人口密集城市）39个区产生的医疗废物，以及未来十年将产生的医疗废物。通过该模型，对伊斯坦布尔在疫情期间及未来10年的医疗废物管理系统进行了分析。该模型试图在可持续发展目标内整合经济、环境和社会目标。其目的是在使大城市估计产生的医疗废物的总固定成本、碳排放成本和运输成本最小化的同时，使人员数量和政府收入最大化。结果表明，即使在疫情条件下，现有设施也足以处理产生的医疗废物。然而，消毒设施的能力可能不足以处理未来十年估计数量的医疗废物。在科穆尔库奥达卫生填埋场附近开设一个消毒设施，每年总管理成本为62450332欧元，将是伊斯坦布尔医疗废物的最佳解决方案。与单用途模型结果相比，多用途模型的总成本大约多42000欧元。敏感性分析表明，医疗废物量对总成本影响最大。这个简单的模型为伊斯坦布尔创建了一个有效的医疗废物管理方案，可为大城市提供一个范例。
