          Abstract

          Aim. The aim of this study is to assess the awareness of biomedical waste management in dental students of various dental colleges of Nepal. Methodology. A structured pretested questionnaire was used among 434 (323 males and 111 females) undergraduate dental students of five different dental colleges of Nepal. First part of the questionnaire was used to describe demographic profile of the participants. Second part of the questionnaire assessed the knowledge, attitude, and practice regarding biomedical waste management. Chi-square test was applied to find out the association between different responses obtained from different colleges. Result. Majority (91.82%) of participants had a positive attitude towards safe management of biomedical waste. Regarding the knowledge of BMW management policies, majority of the students (83.1% to 98.9%) had positive attitude towards the safe management of biomedical waste, whereas more than 50% of the students were unaware of the guidelines laid down by Government of Nepal. Regarding biomedical waste disposal technique in the hospital, only 29.9% to 79.8% are aware; this shows that there is lack of strict protocol in the BMW management. Association between different responses and colleges for “improper waste management causes various health hazards” ranged from 93.3% to 98.9%. Conclusion. There exists a lacuna in the knowledge and practice of biomedical waste management among the undergraduate dental students in Nepal. Since the students had positive attitude towards addressing this concern, workshops and trainings related to proper biomedical waste management would be a step forward towards attaining a healthy environment for the future.

          Medical wastes management in the south of Brazil.

          Trevor Hoppe, M P Ravanello, Durval L. N. Mello … (2004)
          In developing countries, solid wastes have not received sufficient attention. In many countries, hazardous and medical wastes are still handled and disposed together with domestic wastes, thus creating a great health risk to municipal workers, the public and the environment. Medical waste management has been evaluated at the Vacacai river basin in the State of Rio Grande do Sul, Brazil. A total of 91 healthcare facilities, including hospitals (21), health centers (48) and clinical laboratories (22) were surveyed to provide information about the management, segregation, generation, storage and disposal of medical wastes. The results about management aspects indicate that practices in most healthcare facilities do not comply with the principles stated in Brazilian legislation. All facilities demonstrated a priority on segregation of infectious-biological wastes. Average generation rates of total and infectious-biological wastes in the hospitals were estimated to be 3.245 and 0.570 kg/bed-day, respectively.

            Pattern of medical waste management: existing scenario in Dhaka City, Bangladesh

            M Manzurul Hassan, Shafiul Azam Ahmed, K Anisur Rahman … (2008)
            Background Medical waste is infectious and hazardous. It poses serious threats to environmental health and requires specific treatment and management prior to its final disposal. The problem is growing with an ever-increasing number of hospitals, clinics, and diagnostic laboratories in Dhaka City, Bangladesh. However, research on this critical issue has been very limited, and there is a serious dearth of information for planning. This paper seeks to document the handling practice of waste (e.g. collection, storage, transportation and disposal) along with the types and amount of wastes generated by Health Care Establishments (HCE). A total of 60 out of the existing 68 HCE in the study areas provided us with relevant information. Methods The methodology for this paper includes empirical field observation and field-level data collection through inventory, questionnaire survey and formal and informal interviews. A structured questionnaire was designed to collect information addressing the generation of different medical wastes according to amount and sources from different HCE. A number of in-depth interviews were arranged to enhance our understanding of previous and existing management practice of medical wastes. A number of specific questions were asked of nurses, hospital managers, doctors, and cleaners to elicit their knowledge. The collected data with the questionnaire survey were analysed, mainly with simple descriptive statistics; while the qualitative mode of analysis is mainly in narrative form. Results The paper shows that the surveyed HCE generate a total of 5,562 kg/day of wastes, of which about 77.4 per cent are non-hazardous and about 22.6 per cent are hazardous. The average waste generation rate for the surveyed HCE is 1.9 kg/bed/day or 0.5 kg/patient/day. The study reveals that there is no proper, systematic management of medical waste except in a few private HCE that segregate their infectious wastes. Some cleaners were found to salvage used sharps, saline bags, blood bags and test tubes for resale or reuse. Conclusion The paper reveals that lack of awareness, appropriate policy and laws, and willingness are responsible for the improper management of medical waste in Dhaka City. The paper also shows that a newly designed medical waste management system currently serves a limited number of HCE. New facilities should be established for the complete management of medical waste in Dhaka City.

              Improvement and modification of the routing system for the health-care waste collection and transportation in Istanbul.

              Aylin Zeren Alagöz, Günay Kocasoy (2007)
              Handling of health-care wastes is among the most important environmental problems in Turkey as it is in the whole world. Approximately 25-30tons of health-care wastes, in addition to the domestic and recyclable wastes, are generated from hospitals, clinics and other small health-care institutions daily on the European and the Asian sides of Istanbul [Kocasoy, G., Topkaya, B., Zeren, B.A., Kiliç, M., et al., 2004. Integrated Health-care Waste Management in Istanbul, Final Report of the LIFE00 TCY/TR/054 Project, Turkish National Committee on Solid Wastes, Istanbul, Turkey; Zeren, B.A., 2004. The Health-care Waste Management of the Hospitals in the European Side of Istanbul, M.S. Thesis, Boğaziçi University, Istanbul, Turkey; Kiliç, M., 2004. Determination of the Health-care Waste Handling and Final Disposal of the Infected Waste of Hospital-Medical Centers in the Anatolian Side of Istanbul. M.S. Thesis, Boğaziçi University, Istanbul, Turkey]. Unfortunately, these wastes are not handled, collected or temporarily stored at the institutions properly according to the published Turkish Medical Waste Control Regulation [Ministry of Environment and Forestry, 2005. Medical Waste Control Regulation. Official Gazette No. 25883, Ankara, Turkey]. Besides the inappropriate handling at the institutions, there is no systematic program for the transportation of the health-care wastes to the final disposal sites. The transportation of these wastes is realized by the vehicles of the municipalities in an uncontrolled, very primitive way. As a consequence, these improperly managed health-care wastes cause many risks to the public health and people who handle them. This study has been conducted to develop a health-care waste collection and transportation system for the city of Istanbul, Turkey. Within the scope of the study, the collection of health-care wastes from the temporary storage rooms of the health-care institutions, transportation of these wastes to the final disposal areas and the cost-benefit analyses of the existing and the proposed optimum transportation routes are investigated and the most feasible routes from the point of view of efficiency and economy have been determined. In order to solve the scheduling and route optimization problem, special software programs called MapInfo and Roadnet were used. For the program, the geocodes of hospital locations, data about the amount of the health-care wastes generated, the loading and unloading process times, and the capacity of the collecting vehicles were taken into account. The new systems developed aim at the daily collection of the health-care wastes from the institutions and their transportation directly to the final disposal area/facility by using the shortest and the most efficient routes to resolve the routing and scheduling problem and to reduce the cost arising from the transportation.
