Disposal of about 1750tons of solid wastes per day is the result of a rapid population growth in the province of Khuzestan in the south west of Iran. Most of these wastes, especially hospital solid wastes which have contributed to the pollution of the environment in the study area, are not properly managed considering environmental standards and regulations. In this paper, the framework of a master plan for managing hospital solid wastes is proposed considering different criteria which are usually used for evaluating the pollution of hospital solid waste loads. The effectiveness of the management schemes is also evaluated. In order to rank the hospitals and determine the share of each hospital in the total hospital solid waste pollution load, a multiple criteria decision making technique, namely analytical hierarchy process (AHP), is used. A set of projects are proposed for solid waste pollution control and reduction in the proposed framework. It is partially applied for hospital solid waste management in the province of Khuzestan, Iran. The results have shown that the hospitals located near the capital city of the province, Ahvaz, produce more than 43% of the total hospital solid waste pollution load of the province. The results have also shown the importance of improving management techniques rather than building new facilities. The proposed methodology is used to formulate a master plan for hospital solid waste management.

    • "Different decision-making tools have been developed for application in the environmental field such as the Matrix Method, the AHP and the Electre III method. AHP is one of the most practical multiple choice decision making techniques among the available methods widely used [24,28]. It should be explained, currently there is not any installed off-site medical waste treatment facilities in country. "

    ABSTRACT: Treating hazardous-infectious medical waste can be carried out on-site or off-site of health-care establishments. Nevertheless, the selection between on-site and off-site locations for treating medical waste sometimes is a controversial subject. Currently in Iran, due to policies of Health Ministry, the hospitals have selected on-site-treating method as the preferred treatment. The objectives of this study were to assess the current condition of on-site medical waste treatment facilities, compare on-site medical waste treatment facilities with off-site systems and find the best location of medical waste treatment. To assess the current on-site facilities, four provinces (and 40 active hospitals) were selected to participate in the survey. For comparison of on-site and off-site facilities (due to non availability of an installed off-site facility) Analytical Hierarchy Process (AHP) was employed. The result indicated that most on-site medical waste treating systems have problems in financing, planning, determining capacity of installations, operation and maintenance. AHP synthesis (with inconsistency ratio of 0.01 < 0.1) revealed that, in total, the off-site treatment of medical waste was in much higher priority than the on-site treatment (64.1% versus 35.9%). According to the results of study it was concluded that the off-site central treatment can be considered as an alternative. An amendment could be made to Iran's current medical waste regulations to have infectious-hazardous waste sent to a central off-site installation for treatment. To begin and test this plan and also receive the official approval, a central off-site can be put into practice, at least as a pilot in one province. Next, if it was practically successful, it could be expanded to other provinces and cities.

    • "Based on the results of interviews with experts in the field, they tried to reduce overhead costs and enhance medical waste management. Karamouz et al. (2007) presented a framework for managing hospital solid wastes considering different criteria which are usually used for evaluating the pollution of hospital solid waste loads. In order to rank the hospitals and determine the share of each hospital in the total hospital solid waste pollution load, analytical hierarchy process was used. "

    ABSTRACT: Hazardous and toxic industrial wastes may cause or significantly contribute to extensive damage to both humans and the environment when improperly handled. Evaluation of the proper and most appropriate hazardous industrial waste transportation firm is an important problem for hazardous waste generators. In general, many factors affect the appropriate hazardous industrial waste transportation firm selection problem which adheres to uncertain and imprecise data, and usually several people from different functional areas of the company are involved in this process. In this paper, an improved and more effective hazardous industrial waste transportation firm selection model has been developed through integrating VIKOR method with fuzzy set theory. A numerical example is proposed to illustrate an application of the proposed model.

    • "Hospital waste generated from healthcare activities can be classified into two major groups: general waste and hazardous waste. The majority of waste, which is 75–90% of the waste produced by healthcare, is non-risk or general waste that is comparable with domestic or municipal solid waste (Chaerul et al., 2008; Karamouz et al., 2007; Pruss et al., 1999). As general waste is not regulated or defined as hazardous or potentially dangerous waste, it requires no special handling, treatment or disposal (Lee et al., 2004). "

    ABSTRACT: Waste management policy makers always face the problem of how to predict the future amount and composition of medical solid waste, which, in turn, helps to determine the most appropriate treatment, recycling and disposal strategy. An accurate prediction can assist in both the planning and design of medical solid waste management systems. Insufficient budget and unavailable management capacity are the main reasons for the scarcity of medical solid waste quantities and components historical records, which are so important in long-term system planning and short-term expansion programs. This article presents a new technique, using System Dynamics modeling, to predict generated medical solid waste in a developing urban area, based on a set of limited samples from Jenin District hospitals, Palestine. The findings of the model present the trend of medical solid waste generation together with its different components and indicate that a new forecasting approach may cover a variety of possible causative models and track inevitable uncertainties when traditional statistical least-squared regression methods are unable to handle such issues.
