Abstract
Background and Objectives: Not paying attention to management and control of medical wastes in different stages of production, keeping, gathering, transporting and finally eliminating them all have been creating various setbacks such that the environment and human's health are in danger with the relevant consequences. This descriptive cross-sectional study was performed in Vali-e Asr, Amir Kabir, Taleghani, Amir Al-Momenin and Imam Khomeini hospitals of Arak city in 2009. In this research the current condition of gathering, maintaining, transportation and final elimination of hospital wastes of Arak city was investigated .Eventually an appropriate model was introduced.
Material and Methods: Solid wastes were separated, weighed and registered in two sequential intervals. In order to get acquaintance with the management procedure of medical solid wastes in the hospitals studied, a questionnaire approved byW.H.O was used. The questions were then replied by the Managers and Hygiene Experts worked at hospitals and their responses were recorded.
Results: The investigations conducted in 5 hospitals reveal that the average per annual was2.9 Kg in 24 hours per active bed and 4.6 Kg for each patient. This volume consists of 60% for semi-home solid wastes, 39% for infectious solid wastes, 0.34% for sharp wastes, 0.28% for the pathologic and 0.38% for medicinal and chemical solid wastes.
Conclusion: According to the results obtained in this study, in order to reduce pollution create in the hospitals, action should be taken to deal with pollutants at their source of generation. The staff members involved in waste collection and transportation should practice all the personal protection measures.finaly it also should be considered that,success in medical waste management wouldn't be achievable unless all groups of medical staff involved cooperate and participle.

Abstract
Backgrounds and Objectives: Medical waste management is one of the important issues in solid waste managment in each community. This research was carried out to study the quantity, quality and the management practices of solid wastes of hospitals in Zanjan City in 2011.
Materials and Methods: In the present study, the hospital wastes were categoried and weighted into four main categories. Waste management pattern was studied based on a checklist extracted from national guidelines. Then, hospitals were ranked from very poor to excellent classes. For data analysis, Excel soft ware was used.
Results: Waste generation rate was on average 2.402± 0.163 Kg/bed.day in the studied hospitals. The generation rate of domestic waste, infectious waste, sharp wastes, and chemical - pharmacological waste was 1.432±0.059, 0.926±0.096, 0.029±0.0055, and 0.015±0.002 kg/day.bed respectively. The status of the waste management practices was determined as average.
Conclusion: Waste generation rate in the hospitals of Zanjan was lower compared with the expected average value in other cities (e.g. 2.71 Kg/bed.day in Tehran). The percentage of medical waste in Zanjan hospitals was 34, which is higher than W.H.O. recommendations. Therefore, it is strongly recommended to reform and monitor certain solid waste management practices in order to reduce health and environmental issues.

Abstract
Background and Objective: The failure mode and effects analysis (FMEA) is one of risk assessment techniques. The aim of this study was to identify, assess and prioritize the risk associated with the process of medical waste management using the FMEA method and provide appropriate strategies and measures for controlling the risk of this process in the Children's Medical Center Hospital.
Materials and Methods: This descriptive cross-sectional study was performed in this hospital during the first 6 months of 2016. For data collection, the standard worksheet of FMEA and object-oriented sampling were used. In this method, each error based on the severity, the occurrence rate and probability of finding an error is scored between 1 and 10, which the priority number of the risk is obtained from the product of these 3 indicators.
Results: In this study, a total of 33 potential risks associated with the management of medical wastes were identified using FMEA risk assessments. The highest priority number for non-washed waste containers is 360 and the lowest priority number is the risk of not having the Safety box for disposal of sharp waste in the wards, which is 30.
Conclusion: One of the most important sources of environmental pollution is medical wastes that have high costs in different stages of waste management in the hospital, thus, the use of the FMEA technique can reduce costs and increase the safety and health of the personnel. It also helps to preserve the environment.

Abstract
Background and Objective: Clinics, laboratories and health care centers are considered as one of the main waste generating sources in solid waste management. The problems associated with the generated health-care waste in clinics, laboratories and health care centers have been rarely investigated in Iran. Therefore, the present study was developed to investigate the status of health care waste in clinics, laboratories and health care centers of Mahmoudabad, Mazandaran in 2017.
Methods and Materials: This cross-sectional study was conducted to determine the status of solid waste management in 117 medical centers in Mahmoudabad, Mazandaran, 2017. The solid waste data in terms of waste generation rate, storage, collection, and disposal were surveyed through interview and questionnaire that were validated by Iran’s ministry of health.
Results: The average health-care waste generation in medical centers in Mahmoudabad was found to be 248 g/day. The mean and standard deviation for environmental health criteria in all medical centers were 248.3 and 41.1, respectively. In addition, there was a statistically significant difference between the amount of waste generation in private and governmental medical centers (p=0.111).
Conclusion: The results obtained from the present research indicated that the medical waste management in Mahmoudabad, particularly in private centers, face serious problems. Improper waste collection technology, mixing municipal and medical waste, requirement for training the personnel in medical waste management and surveillance can be considered as important concerns in health-care waste management in Mahmoudabad.

Abstract
Background and Objective: Medical waste is among the environmental problems. Failure to manage these wastes leads to the prevalence of various diseases. This study aimed to rank the educational hospitals of SBUMS by assessing medical waste reduction.
Materials and Methods: First, a review of past national and international studies was performed and accordingly, 12 criteria and 30 sub-criteria for reduction of medical waste production were selected. After developing a questionnaire based on such criteria, data was collected from six SBUMS hospitals. Then, TOPSIS and VIKOR techniques in MATLAB were used as ranking methods of hospitals.
Results: The combined results of TOPSIS and VIKOR methods using weighted average indicated that Hospital (C), Hospitals (B) and (A) were respectively ranked first, second and third in terms of waste management. Moreover, the effective measures to reduce the amount of waste production and to improve the waste management system include human resource, management support, proper management of supplies, proper model of service delivery, quality of supplies and equipment, and waste sorting at source.
Conclusion: A combined method consisting of TOPSIS and VIKOR for evaluation of ranking of hospitals in terms of waste management can be a helpful tool in planning waste management, and can provide a basis for improving measures and promoting programs and activities.

Abstract
Background and Objective: Due to the importance of managing medical sharps waste and the potential harm caused by these types of waste, the use of safe technologies that simultaneously encapsulate and reduce their volume is considered one of the essential needs for managing medical waste in hospitals and other healthcare facilities. The main objective of this study was to investigate the efficiency of disinfecting and encapsulating device for medical sharps waste.
Materials and Methods: This device provides the process of containment and encapsulation of medical sharps waste by creating a stable protective foam without oxidation through inductive heat in a closed environment, preventing the dispersion and release of these wastes. Gas samples from the device's output were collected using the NIOSH 1501 method and analyzed using GC-MS. The performance efficiency of the device was evaluated based on the biological monitoring of the indicator bacterium Bacillus stearothermophilus.
Results: The results showed that the average concentration of BTEX gases (benzene, toluene, ethylbenzene, and xylenes) and other volatile organic compounds in the device's output was within the permissible limit. The concentrations of Benzene, Toluene, Ethylbenzene and Xylene gases were 0.04, 0.033, 0.029, and 0.029 ppm, respectively. The results of biological monitoring showed that the reduction of the microbial load was 9999.99 (Log 6) and the decontamination process was acceptable.
Additionally, this device has the advantage of reducing the volume of sharp and plastic objects during the encapsulation process, which can be further used in plastic pyrolysis/recycling industries.
Conclusion: It is hoped that by using this innovative and domestic device in the decontamination units of hospitals across the country, we can take an effective step towards improving medical waste management, reducing waste production, reducing hospital costs, and preserving and enhancing the country's health.
