Medical waste refers to infectious waste generated by businesses dealing with medical services. Medical waste logistics includes the collection, temporary storage, transportation and disposal of medical waste activities without harming the environment [1,2]. In the field of public health, waste collected regularly from private clinics, health centers, veterinary clinics, pharmacies and the homes of dialysis patients is tried to be rendered harmless to the environment. Management of the medical waste recycling process prevents many potential health risks, including virus transmission. It is mandatory to properly collect and dispose of medical wastes that may pose a risk to the environment [3]. In the process of collecting medical waste, it is useful to utilize the vehicle routing problem that evaluates the safety scores of health centers, and thus the urban environment and human health can be protected. In this study, a vehicle routing problem related to the medical waste collection process from hospitals to disposal centers is discussed. First of all, the safety scores of hospitals are calculated with Best Worst Method which is a multi-criteria decision making method developed by Rezaei [4,5]. In selecting the criteria, studies in the literature have been used. This study also proposes a new mathematical model with safety scores and distances, giving priority to hospitals with low safety scores for the process of collecting medical waste from hospitals. The mathematical model was coded in GAMS software, and the results were interpreted on the basis of the objective function, using different weight sets for the results. The computational experiments demonstrate that shortest distance tours and high security collection are provided.
