“…Autoclaves and microwaves operate using this technique [6,33]. Chemical processes where chemicals and disinfectants like sodium hypochlorite, sodium dioxide, peracetic acid or lime solution are react with the waste to destroy the constituent pathogens [6,34]. Biological processes: enzyme mixtures are used to decompose organic matters [4,6].…”

Waste generated form healthcare facilities is a potential source of health risks to the public, if it is not properly handled from the point of generation to disposal. This study was conducted to assess the efficiency of healthcare risk waste (HCRW) management in Vhembe District of Limpopo Province, South Africa. Fifteen healthcare facilities were selected in Vhembe District for this study. Data were obtained through in-depth interviews, semi-structured questionnaires, observation and pictures. Qualitative data were thematically analyzed, while the quantitative data were analyzed using the Statistical Package for the Social Sciences, version 25. In all the healthcare facilities; mismanagement of HCRW was noted at different points along the management chain. Poor segregation, overfilling of waste bins, inappropriate transportation and storage of waste in substandard storage rooms were observed in the facilities. All the waste from the district are transported to a private-owned treatment facility outside the district, where they are mainly incinerated. Enforcement of healthcare risk waste guidelines, provision of standardized equipment for temporary storage, empowerment of each healthcare facility to treat at least some of the waste, and employment of non-burn techniques for treatment of waste are recommended for more efficient management of healthcare risk waste in Vhembe District.

“…A systematic and rigorous approach is required to effectively address this imperative issue. ID:p0085 A number of studies indicated the significance of the appropriate waste treatment technology selection [9,11,13]. The selection of appropriate waste treatment technology is considered to be a complex decision problem, which can be effectively handled by the methods of MCDM.…”

Health-care waste management HCW treatment technology selection Intuitionistic fuzzy sets DEMATEL ANP AHP ID:p0065 Healthcare waste (HCW) management has become a major environmental and public-health concern especially in developing countries, and therefore, it has been receiving increasing attention from both industrial practitioners and researcher in recent years. Selection of the optimal treatment technology for HCW is regarded as an intricate multi-criteria decision-making problem involving conflicting and intertwined qualitative as well as quantitative evaluative criteria. To address this decision problem, we develop an integrated decision support framework based on decision-making trial and evaluation laboratory (DEMATEL), intuitionistic fuzzy ANP, and intuitionistic fuzzy AHP. The DEMATEL method determines the influences of main factors and criteria and produces a network relationship map while the ANP method calculates the degree of interrelationship among evaluative criteria and obtains their relative weights. The AHP method assesses the HCW treatment alternatives over evaluative criteria. The experts' opinions are collected in form of intuitionistic fuzzy preference relations as they are effective in capturing uncertainty and hesitancy involved in decision-makers' judgment. We also develop a priority method to derive nonfuzzy weights from the intuitionistic fuzzy preference relations. To validate the feasibility of the proposed approach, a case study is carried out on the selection of optimum HCW treatment technology for Chhattisgarh, India. The analyses of the results indicate that the proposed integrated multi-criteria decision making (MCDM) framework effectively handles the issue of HCW treatment technology selection in uncertain environments.

“…The choice of treatment technology is also important. For example, the proper treatment technology for cytostatic waste is incineration, whereas both incineration and disinfection can be used for infectious waste (Voudrias, 2016). Quantification of cytostatic waste generation is also important for health and safety reasons and for assessing their environmental impact, when they are released in the environment.…”

<p>The objective of this work was to determine the composition and production rate of cytostatic pharmaceutical waste produced by Theagenion Cancer Treatment Hospital (TCTH) in Thessaloniki, Greece. This information is necessary for the design and costing of management systems for cytostatic pharmaceutical waste, for assessing their environmental impact and for health and safety considerations. A total of 826 kg cytostatic pharmaceutical waste was collected, manually separated and weighed over a period of ten working weeks. Total cytostatic pharmaceutical waste was classified in three categories, vial waste comprising 38.3%, syringe waste with 4.5% and intravenous therapy (IV) waste with 57.2% of the total. Vial waste only was classified according to the active ingredients in alkylating agents, antimetabolites, cytotoxic antibiotics, Vinca alkaloids and “other” antineoplastic drugs. The overall cytostatic waste production by the hospital was 22900(6955) g/d, with numbers in parenthesis representing standard deviations. The average unit production rates of total cytostatic pharmaceutical waste were 140(64) g/patient/d and 201(61) g/bed/d. The respective unit production rates were: (1) for vial waste 41(11) g/patient/d and 77(46) g/bed/d, (2) for syringe waste 5(1.5) g/patient/d and 9(5) g/bed/d and (3) for IV waste 94(63) g/patient/d and 115(43) g/bed/d.</p>
