Assessing future scenarios for health care waste management using a multi-criteria decision analysis tool: A case study in the Turkish West Black Sea Region

Abstract

The aim of this paper is to identify the best possible health care waste management option in the West Black Sea Region by taking into account economic, social, environmental, and technical aspects in the concept of multi-criteria decision analysis. In the scope of this research, three different health care waste management scenarios that consist of different technology alternatives were developed and compared using a decision-making computer software, called Right Choice, by identifying various criteria, measuring them, and ranking their relative importance from the point of key stakeholders. The results of the study show that the decentralized autoclave technology option coupled with the disposal through landfilling with energy recovery has potential to be an optimum option for health care waste management system, and an efficient health care waste segregation scheme should be given more attention by the authorities in the region. Furthermore, the discussion of the results points out multidisciplinary approach and the equilibrium between social, environmental, economic, and technical criteria. The methodology used in this research was developed in order to enable the decision makers to gain an increased perception of a decision problem. In general, the results and remarks of this study can be used as a basis of future planning and anticipation of needs for investment in the area of health care waste management in the region and also in developing countries that are dealing with the similar waste management problems.Implications: Alternative technologies are not capable to treat some categories of health care wastes, and Turkish practice has to be revised urgently. In doing so, internal health care waste separation is critical for determination of treatment technology. The author verified the methodology in a decision-making framework for a real-world problem. Results indicated that incinerating all health care wastes is not a feasible option due to high cost.

Materials Flow Analysis as a Tool to Improve Solid Waste Management: A Case of Ankara

“…Secondly, the use of a standard method for the assessment of solid waste management in any region and the spread of these studies in different regions will give researchers the ability to compare their results. As it is known, the use of different terminology in the solid waste literature causes the results obtained for different regions not to be compared or misinterpreted (Ciplak 2015). For example, when the values expressed by "amount of solid waste" are compared for cities A and B, it may be concluded that city A produces more solid waste.…”

Assessment of Waste Management in Healthcare Industry by using DEMATEL Technique

“…Ciplak [7] recognize the best one in the waste management system of Turkish healthcare industry by using MCDM technique. The findings of the study displaying that landfilling disposal with the recovery of energy is the best one in the system and they give special care to segregation of waste.…”

Risk Factors in the Process industry by using MCDM Methods: Literature from 2014 to 2019

“…From the above study, alternatives like sequential batch reactor and aerated lagoon acts as a major role in this process. Ciplak [22] conducted the assessment of waste management in the western sea zone of Turkish country by using MCDM method. The outcomes depict that technology with decentralized autoclaves is the most preferable option for waste management and they give more importance to the disposal by landfilling.…”
