Objective: To evaluate the opinions of university-level Health Sciences students about unused, leftover and expired medicine, as well as their disposal practices, and to classify the medicines. METHODS: The cross-sectional study was conducted from April 1 to May 31, 2023, at the Faculty of Health Sciences, Burdur Mehmet Akif Ersoy University, Turkey, and comprised those studying at the Nursing, Nutrition Dietetics and Physical Therapy and Rehabilitation departments. Data was collected using Google Forms. The Anatomical Therapeutic Chemical classification was used for classifying pharmaceutical active ingredients. Data was analysed using SPSS 24. RESULTS: Of the 373 participants, 272(73%) were females and 101(27%) were males. The overall mean age was 20.8±2.8 years. There were 348(93.3%) subejcts who reported having a total of 845 boxes of leftover and unused medicines in their homes (2.3±1.9 per capita), while 25(6.7%) participants had none. The medicines were stored in the kitchen 261(61.5%) as the storage area, and in the refrigerator 181(40.2%) as the storage unit. The expired medicine was disposed of in the garbage in 328(86.1%) cases. Self-medication was prevalent in 325(87.1%) cases. Anatomical Therapeutic Chemical classification analysis showed that paracetamol, acetylsalicylic acid, paracetamol+caffeine and metamizole sodium was the most common group of leftover and unused medicines 283(81.3%). Conclusion: High prevalence of unused and leftover medicine, disposal of medicine in household garbage, and selfmedication behaviour indicated a serious public health and environmental problem.

An investigation into waste handler's knowledge of management of isolation waste: A case study of Dr George Mukhari Academic Hospital, Gauteng, South Africa.

BACKGROUND: The proper management of isolation waste is of utmost importance in healthcare facilities to prevent the spread of infections and protect both healthcare workers and the general public. This study investigated waste handlers' knowledge of the management of isolation waste at Dr. George Mukhari Academic Hospital in Gauteng, South Africa. METHODS: A survey was conducted to assess waste handlers' understanding of waste types, colour codes, safety precautions, and awareness of internal policies related to isolation waste management. RESULTS: The study found that the majority of waste handlers demonstrated a good understanding of waste types generated in the isolation unit, including sharps waste, human tissue waste, infectious waste, and general waste. They also correctly identified examples of sharp waste, such as injections, blades, glass slides, and needles. Additionally, most respondents were aware of the colour code used for representing infectious waste as "yellow" and "red." The study revealed a statistically significant association between waste handlers' age and their knowledge of isolation waste, suggesting that age may influence their understanding of waste management practices. Furthermore, experience was found to be significantly associated with waste handlers' knowledge of the health-hazardous nature of isolation waste. While the majority of waste handlers recognized the importance of wearing protective clothing and correctly marking isolation waste, some respondents were not aware of the internal policy for waste handling such as guidelines and protocols specific to the segregation, packaging, labeling, and disposal of waste generated within the isolation units. CONCLUSION AND CONTRIBUTION: These findings highlight the importance of continuous training, targeted education, and policy dissemination to ensure effective waste management and adherence to safety protocols among waste handlers.

METHOD: Qualitative research, whose theoretical and methodological references were, respectively, Complexity Theory and Grounded Theory. A total of 30 nursing professionals from a public hospital in Rio de Janeiro participated in the study, between January and August 2022. A semi-structured interview was used for data collection. RESULTS: The professionals indicate the need for better knowledge about waste management in healthcare services, while revealing their understanding on the importance of this process and of themselves as important elements in impacting the environment and health. CONCLUSION: The complexity of the meanings attributed to healthcare waste management practices indicates the dialogue between the fragility of nursing professionals' knowledge and their expanded perceptions about the impacts they can have on this reality.

Review of sustainable practices for the gynecology operating room.

PURPOSE OF REVIEW: Climate change has immediate impacts on women's health. Hospitals and operating rooms are large contributors to greenhouse gas (GHG) emissions and waste. This article will review current green initiatives designed to minimize environmental impact in the operating room and highlight areas for future improvement. RECENT FINDINGS: From a materials perspective, reusable goods result in less GHG emissions while being just as efficacious, well tolerated, and easy to use. Materials should be opened judiciously, only as necessary. Processing regulated medical waste produces greater GHG emissions, so waste should be properly sorted, and items which are not biohazard waste should be processed separately. Choosing appropriate anesthesia and utilizing an 'off' setting, in which operating rooms are shut down when not in use, can also drastically decrease the environmental impact of surgery. Further research is needed to determine effective implementation in hospitals. SUMMARY: This article summarizes current attempts to make operating rooms more sustainable. Many practices result in a decreased carbon footprint and cost savings without adversely affecting patient outcomes. Gynecologic surgeons and the hospitals in which they practice need to focus on implementing these changes in a timely fashion.

Does Reusable Instrumentation for Four-Anchor Rotator Cuff Repair Offer Decreased Waste Disposal Costs and Lower Waste-Related Carbon Emissions?

INTRODUCTION: Orthopaedic surgery is culpable, in part, for the excessive carbon emissions in health care partly due to the utilization of disposable instrumentation in most procedures, such as rotator cuff repair (RCR). To address growing concerns about hospital waste, some have considered replacing disposable instrumentation with reusable instrumentation. The purpose of this study was to estimate the cost and carbon footprint of waste disposal of RCR kits that use disposable instrumentation compared with reusable instrumentation. METHODS: The mass of the necessary materials and their packaging to complete a four-anchor RCR from four medical device companies that use disposable instrumentation and one that uses reusable instrumentation were recorded. Using the cost of medical waste disposal at our institution ($0.14 per kilogram) and reported values from the literature for carbon emissions produced from the low-temperature incineration of noninfectious waste (249 kgCO 2 e/t) and infectious waste (569 kgCO 2 e/t), we estimated the waste management cost and carbon footprint of waste disposal produced per RCR kit. RESULTS: The disposable systems of four commercial medical device companies had 783%, 570%, 1,051%, and 478%, respectively, greater mass and waste costs when compared with the reusable system. The cost of waste disposal for the reusable instrumentation system costs on average $0.14 less than the disposable instrumentation systems. The estimated contribution to the overall carbon footprint produced from the disposal of a RCR kit that uses reusable instrumentation was on average 0.37 kg CO2e less than the disposable instrumentation systems. CONCLUSION: According to our analysis, reusable instrumentation in four-anchor RCR leads to decreased waste and waste disposal costs and lower carbon emissions from waste disposal. Additional research should be done to assess the net benefit reusable systems may have on hospitals and the effect this may have on a long-term decrease in carbon footprint. LEVEL OF EVIDENCE: Level II.

A study of the stabilization and solidification of heavy metals in co-vitrification of medical waste incineration ash and coal fly ash.

Medical waste incineration ash (MWIA) has significant concentrations of heavy metals, dioxins, and chlorine that, if handled incorrectly, might cause permanent damage to the environment and humans. The low content of calcium (Ca), silicon (Si), and aluminum (Al) is a brand-new challenge for the melting technique of MWIA. This work added coal fly ash (CFA) to explore the effect of melting on the detoxication treatment of MWIA. It was found that the produced vitrification product has a high vitreous content (98.61%) and a low potential ecological risk, with an initial ash solidification rate of 67.38%. By quantitatively assessing the morphological distribution features of heavy metals in ashes before melting and molten products, the stabilization and solidification rules of heavy metals during the melting process were investigated. This work ascertained the feasibility of co-vitrification of MWIA and CFA. In addition, the high-temperature melting and vitrification accelerated the detoxification of MWIA and the solidification of heavy metals.

Experimental and modeling study of medical waste based on plasma gasification.

Plasma gasification melting (PGM) provides reliable disposal of toxic medical waste with a low heating value, which is capable of converting waste into energy. This study investigates the performance of experiments on plasma gasification for the treatment of chemical-pharmaceutical medical waste (CPMW) with an air medium. A comparative analysis is performed for gasification characteristics at three reactor temperatures (1000, 1400, and 1800 °C). Moreover, a thermodynamic equilibrium model is developed to assess performance features such as syngas yield, high heating value, and cold gas efficiency in the gasification temperature range of 1000-1800 °C. A comparison of the experiment and computational outcomes shows a good agreement. The results show that the quality of syngas and heating value is improved by increasing the temperature of the plasma gasifier so that at 1800 °C, H2, CO, and higher heating value (HHV) are obtained as 41 %, 37 %, and 10 MJ/Nm3, respectively. The obtained syngas is a clean fuel with low sulfur-containing and nitrogen-containing. The experimental results provide an extensive comprehension of CPMW gasification in a plasma reactor and consider a possibility for hydrogen and energy production.

Public awareness, knowledge, and attitude regarding proper disposal of unused medicines and associated factors in Gondar city, northwest Ethiopia.

Background: Proper disposal of unwanted medicines, in addition to reducing wastage, has a positive impact on the environment and public health. Improper disposal of medications increases the risk of accidental poisonings, particularly among children. This study aimed to assess the level of knowledge, attitudes, and awareness regarding the proper disposal of unused medicines in Gondar city, northwest Ethiopia. Method: From 30 July to 30 August 2023, a community-based cross-sectional study was conducted among the public in Gondar city. The data were gathered using the Kobo toolbox, exported into an Excel sheet, and then analyzed using SPSS version 27. Multivariate and bivariate binary logistic regressions were performed. A p-value of 0.05 with a 95% confidence interval (CI) was used to determine statistical significance. Result: From 786 study participants, the overall knowledge and attitude of the community toward the proper disposal of unused medicines were 42.6 and 42.9%, respectively. Factors identified in this study included ages between 19 and 25 [AOR = 6.91, 95% CI: (3.45, 13.84); education level: secondary [AOR = 11.82, 95% CI: (1.01, 3.29)] and college and above [AOR = 5.68, 95% CI: (2.25, 14.30)]; prior information [AOR = 6.41; 95% CI: (4.02, 10.22)]; and good attitudes [AOR = 2.11; 95% CI: (1.47, 3.02)]] as factors associated with good knowledge toward proper disposal of unused medicines. In addition, receiving information [AOR = 1.86 95% CI: (1.22, 2.86)], taking medication in the past 6 months [AOR = 1.61, 95% CI: (1.09, 2.38)], and being knowledgeable [AOR = 2.07 95% CI: (1.46, 2.94)] were factors contributing to positive attitudes toward the disposal of unused medicines among the general public. Furthermore, approximately 369 participants (46.9%) in our study lacked awareness about the harmful effects of disposing of unused medicine in regular waste. Conclusion: A relatively low level of knowledge and attitudes about the proper disposal of unused medications is present in the community. In this regard, a well-coordinated and methodical public awareness campaign is recommended to disseminate information and promote the appropriate disposal of unused medications.

Can pyrolysis handle biomedical wastes?: Assessing the potential of various biomedical waste treatment technologies in tackling pandemics.

Globally, COVID-19 has not only caused tremendous negative health, social and economic impacts, but it has also led to environmental issues such as a massive increase in biomedical waste. The biomedical waste (BMW) was generated from centralized (hospitals, clinics, and research facilities) and extended (quarantine camps, COVID-19 test camps, and quarantined homes) healthcare facilities. Many effects, such as the possibility of infection spread, unlawful dumping/disposal, and an increase in toxic emissions by common BMW treatment facilities, are conjectured because of the rise in waste generation. However, it is also an opportunity to critically analyze the current BMW treatment scenario and implement changes to make the system more economical and environmentally sustainable. In this review, the waste disposal guidelines of the BMW management infrastructure are critically analyzed for many functional parameters to bring out possible applications and limitations of individual interventions. In addition, an investigation was made to select appropriate technology based on the environmental setting.

A multisectoral approach to medication safety in Kuwait using the take-back campaign.

Background: The take-back campaign, which focuses on enhancing public awareness, safe medication disposal practices, stakeholder engagement and patient participation was used to promote medication safety in Kuwait. Aim: To evaluate the effectiveness of the take-back campaign in promoting medication safety in Kuwait. Methods: The campaign was implemented systematically through several stages of planning, communication and coordination among several stakeholders. This social media campaign encouraged individuals from the participating healthy cities to bring unwanted medications to designated collection centres. Returned medications were categorized based on the British National Formulary and data analysis was conducted using Excel. Consultations were held at the collection sites to increase patient confidence in medication compliance and safety. The medications were sorted and disposed safely. Results: The take-back campaign lasted 56 hours over a period of one month. It successfully engaged 405 households and collected 1005 kg of medication, comprising 7648 items, over a period 6 working days. Fifty-seven percent of the medications collected through the campaign originated from the Ministry of Health and 43% from the private sector. Fifty-two percent had expired and 59% were in solid dosage form. Painkillers comprised the largest group (18%) among the returned medications. Conclusion: The take-back campaign effectively raised awareness about medication safety and provided a safe disposal mechanism for unused and expired medications. This campaign has provided a foundation for future initiatives and contributed significantly to improving medication safety and public health outcomes in Kuwait.

Public attitudes toward medical waste: Experiences from 141 countries.

BACKGROUND: Medical Waste (MW), conceptualized as waste generated in the diagnosis, treatment, or immunization of human beings or animals, posing massive threat to public health. Environment-friendly public attitudes promotes the shaping of pro-environmental behavior. However, the public attitudes of MW and the potential determinants remained scarce. The present study aims to reveal globally public attitudes towards MW and captured the determinants. METHODS: We integrated the crawler technology with sentiment analysis to captured the public attitudes toward MW across 141 specific countries from 3,789,764 related tweets. Multiple cross-national databases were integrated to assess characteristics including risk, resistance, environment, and development. The spatial regression model was taken to counterbalence the potential statistical bias. RESULTS: Overall, the global public attitudes towards MW were positive, and varied significantly across countries. Resilience (ß = 0.78, SD = 0.14, P < 0.01) and development (ß = 1.66, SD = 0.13, P < 0.01) posed positive influence on public attitudes towards MW, meanwhile, risk (ß = -0.1, SD = 0.12, P > 0.05) and environment (ß = 0.09, SD = 0.09, P > 0.05) were irrelated to the shaping of positive MW public attitudes. Several positive moderating influences was also captured. Additionally, the cross-national disparities of the determiants were also captured, more specific, public attitudes towards MW in extremely poor areas were more likely to be negatively affected by risks, resilience and development. CONCLUSIONS: This study focused mainly on the public attitudes as well as captured the potential determinants. Public attitudes towards MW were generally positive, but there were large cross-national disparities. Stakeholders would need to designate targeted strategies to enhance public satisfaction with MW management.

Impact of medical waste bin on contamination of patient's environment: An experimental study.

BACKGROUND: Medical waste bins are a potential source of microbial contamination in the hospital environment, while there is no clear guidance for the management of them. We aimed to assess the impact of medical waste bins on patient's environment. METHODS: This experimental study simulated microbial contamination by performing medical procedures on a patient model with fluorescent lotion. The waste bin was set as initially empty or two-thirds filled with waste, open or with a lid. The percentage of fluorescent-contaminated area in designated patient's environments was analyzed by 2 independent observers. RESULTS: Among a total of 120 experiments, the sides of the bins were more contaminated in open-occupied bins compared to open-empty bins and in open-occupied bins compared to lid-occupied bins (median 1.9175% vs 0.0916% [P = .001] and 1.9175% vs 0.0899% [P = .003], respectively). The top of the bedside equipment trolley for preparing medical procedures was more contaminated in lid-occupied bins than open-occupied bins (median 0.0080% vs 0.0040%, P = .013). DISCUSSION: In addition to reducing contamination of the bin itself, the manually operated lid had a potential risk of contributing to microbial transmission by contaminating the equipment trolley. CONCLUSIONS: Medical waste bins should be kept no more than two-thirds full, and caution should be taken when using the manually operated lid, to avoid cross-contamination.

Handling 'carbon footprint' in orthopaedics.

INTRODUCTION: The National Health Service contributes 4%-5% of England and Wales' greenhouse gases and a quarter of all public sector waste. Between 20% and 33% of healthcare waste originates from a hospital's operating room, and up to 90% of waste is sent for costly and unneeded hazardous waste processing. The goal of this study was to quantify the amount and type of waste produced during a selection of common trauma and elective orthopaedic operations, and to calculate the carbon footprint of processing the waste. METHODS: Waste generated for both elective and trauma procedures was separated primarily into clean and contaminated, paper or plastic, and then weighed. The annual carbon footprint for each operation at each site was subsequently calculated. RESULTS: Elective procedures can generate up to 16.5kg of plastic waste per procedure. Practices such as double-draping the patient contribute to increasing the quantity of waste. Over the procedures analysed, the mean total plastic waste at the hospital sites varied from 6 to 12kg. One hospital site undertook a pilot of switching disposable gowns for reusable ones with a subsequent reduction of 66% in the carbon footprint and a cost saving of £13,483.89. CONCLUSIONS: This study sheds new light on the environmental impact of waste produced during trauma and elective orthopaedic procedures. Mitigating the environmental impact of the operating room requires a collective drive for a culture change to sustainability and social responsibility. Each clinician can have an impact upon the carbon footprint of their operating theatre.

Variability of the treated biomedical waste disposal behaviours during the COVID lockdowns.

Literature review suggests that studies on biomedical waste generation and disposal behaviors in North America are limited. Given the infectious nature of the materials, effective biomedical waste management is vital to the public health and safety of the residents. This study explicitly examines seasonal variations of treated biomedical waste (TBMW) disposal rates in the City of Regina, Canada, from 2013 to 2022. Immediately before the onset of COVID-19, the City exhibited a steady pattern of TBMW disposal rate at about 6.6 kg∙capita-1∙year-1. However, the COVID-19 pandemic and its associated lockdowns brought about an abrupt and persistent decline in TBMW disposal rates. Inconsistent fluctuations in both magnitude and variability of the monthly TBMW load weights were also observed. The TBMW load weight became particularly variable in 2020, with an interquartile range 4 times higher than 2019. The average TBMW load weight was also the lowest (5.1 tonnes∙month-1∙truckload-1) in 2020, possibly due to an overall decline in non-COVID-19 medical emergencies, cancellation of elective surgeries, and availability of telehealth options to residents. In general, the TBMW disposal rates peaked during the summer and fall seasons. The day-to-day TBMW disposal contribution patterns between the pre-pandemic and post-pandemic are similar, with 97.5% of total TBMW being disposed of on fixed days. Results from this Canadian case study indicate that there were observable temporal changes in TBMW disposal behaviors during and after the COVID-19 lockdowns.

Healing patient, harming planet? A drive towards sustainable surgery: review of waste production and recyclability of surgical instrument packaging.

INTRODUCTION: Healthcare contributes more than 1% of all domestic waste in the United Kingdom (UK), with operating theatre waste alone accounting for approximately 50% of all hospital waste. In November 2022, the UK Surgical Royal Colleges issued an Intercollegiate Climate Emergency Declaration and called for urgent action. We review waste production and the recyclability of surgical instrument packaging used in a common ear, nose and throat procedure (thyroidectomy) and suggest strategies to make this surgery more sustainable,. These strategies can be generalised to other surgeries. METHODS: We prospectively audited packaging waste from 20 thyroidectomies performed at the Royal Marsden Hospital in the UK between July and December 2022. All packaging was weighed, categorised and analysed after the operation. RESULTS: On average, each thyroidectomy produced packaging waste comprising 183g (34%) of plain paper/cardboard, 167g (31%) of soft plastic film, 142g (26%) of laminated paper, 37g (7%) of hard plastic and 11g (2%) of metal foil. Of all the packaging collected, only one item had a recycling label. When extrapolated to the 7,851 thyroidectomies performed in the National Health Service during the fiscal year 2021/2022, the estimated total weight of packaging waste would be 4.2 tonnes, of which only 31.4kg would be indicated as recyclable. When converted to an estimated carbon footprint, total carbon emissions would be 1,048kg CO2e, equivalent to three round trips from London to Edinburgh in a petrol car. CONCLUSION: This audit demonstrates the different categories and vast amount of packaging waste from a common operation. Manufacturers should place clear recyclability labels on packaging, and switch to recyclable materials and a digital information booklet where possible. Local waste audit and analysis can be simple first steps towards making surgery more sustainable.

Simulation clinic waste audit assessment and recommendations at the University of Washington School of Dentistry.

OBJECTIVE: Dentistry produces waste contributing to climate change and adverse health outcomes, thus reducing waste is essential; however, there has been minimal emphasis on sustainability or climate action in dentistry. Waste audits quantify the type and amount of waste produced and may inform waste reduction strategies. We conducted a waste audit to identify areas of potential waste reduction and recommend interventions to reduce waste. METHODS: In this cross-sectional study, we conducted a waste audit of garbage produced during a typical 4-hour pre-clinical restorative dentistry simulation exercise. The sample was composed of 72 second-year dental students. This exercise is part of a standard curriculum with a uniform format regarding supplies used and participants. Potentially infectious materials were not used during this exercise. RESULTS: In total, 26.6 kg of waste was discarded. Plastic was the largest contributor by mass (57.5%), followed by paper barriers (19.6%), then impression materials (6.5%). We found 894 gloves and 70 masks discarded. CONCLUSIONS: Based on these findings, we categorized waste reduction opportunities into policy changes, purchasing sustainable materials, and increasing awareness through education. Specific suggested actions include: relaxing glove and gown requirements during laboratory simulations; replacing single use items with more sustainable options; increasing use of intraoral scanners; and posting informational signage with examples of what can be recycled.

Potential of solid recovered fuel production from autoclave treated healthcare waste in Sultanate of Oman.

Economic growth has a potential impact on waste generation worldwide. Growing recognition for resources recovery from waste including production of a clean energy has led to the development of standards for, and the generation of, Solid Recovered Fuel (SRF). SRF, according to BS EN ISO 21640 is a fuel prepared from nonhazardous/treated waste to be utilized for energy recovery in incineration or co-incineration plants which meets the classification and specification. The amount of combustible fractions (i.e., plastic, textile and paper) that are present in Healthcare Waste (HCW) and Municipal Solid Waste (MSW) provides an opportunity for SRF production. HCW is defined as clinical waste generated from healthcare facilities. Limited efforts in utilizing treated HCW in production of SRF were noted, despite the fact that high content of combustible fractions, hence the novelty of this research. This research addresses the opportunities of utilizing autoclaved HCW as an alternate fuel; through a detailed chemical and physical analysis of autoclaved HCW collected from the Sultanate of Oman hospital and healthcare facilities. Furthermore, this study examines the possible uses of such materials instead of landfilling. The utilization of treated HCW as an alternative fuel is not only saving the land space, but also reduces the carbon emissions originating from landfilling. This in fact would also support the government in achieving its aspiring goal of the net zero carbon emissions by 2050 through better utilization of these materials in production of SRF as an alternative to fossil fuel combustion. The study revealed that autoclaved HCW appears to have a high quality SRF and is classified as (NCV 4, Cl 3); which complies with the potential end users' specifications. It is estimated that the combined energy output from MSW and HCW combustible fractions could cover about 12.75% of the energy requirements for Oman cement factories.Implications: The results confirm the viability of using autoclave (HCW) as an alternative fuel due to its high thermal energy content. Based on mean Net Calorific Value (NCV) of analyzed HCW that is found around 14 (MJ/Kg (ar)), and the mean Cl level (i.e., 0.814 ± 0.213% (d)); the SRF is classified as (NCV4, Cl 3). This grade is found to be well within the end users accepted range. This opens up the opportunity for creating a market demand for HCW that not only it could boost its recovery, but it could also unlock the value that can generates.

Healthcare waste generation and quantification in public health centres in Addis Ababa, Ethiopia.

BACKGROUND: Healthcare waste produced in healthcare activities entails higher risk of infection and injuries than municipal waste. In developing countries healthcare waste has not received much attention and has been disposed of together with municipal wastes. Modern method of disposal of healthcare waste have been introduced to most healthcare institutions mismanagement and increased in production in public health centres in Ethiopia is important issues. The aim of the study was to assess the type of healthcare waste generation and quantification in selected public health centres in Addis Ababa, Ethiopia. METHODS: An institution based cross-sectional study were conducted from January to February 2018. Fifteen health centres in Addis Ababa City Administration were selected for this study. Data were collected by using by different color plastic bags (Black plastic bags for non-hazardous wastes, Yellow plastic bags for hazardous wastes and Yellow safety box for needles and Red bags for pharmaceutical wastes and toxic wastes). The collected wastes were measured by weighing scale and were written to data entry sheet. To assure the data quality calibration of weighing scale was made by the standard weight every morning. EPI INFO TM7 and IBM SPSS were used for data entry, cleaning and analysis. RESULTS: The mean healthcare waste generation was 10.64+5.79Kg/day of which 37.26% (3.96+2.20Kg/day) was general waste and 62.74% (6.68+4.29) was hazardous waste from the studies health centres. Total hazardous waste; sharps, infectious, pathological and pharmaceutical wastes constitutes mean (±SD) 0.97 ±1.03, 3.23 ± 2.60, 2.17±1.92 and 0.25 ±0.34 kg/day respectively. Healthcare waste 29.93% and 0.32% were generated from delivery and post-natal case team and nutrition and growth monitoring case team respectively. The annual mean+ SD of healthcare waste generation rate per health centres were 3807.53+ 2109.84 Kg/year. CONCLUSION: The finding in this study showed there was an increased in hazardous healthcare waste in amount as compared to the WHO standard 85% non-hazardous waste and 10% hazardous waste and 5% toxic wastes. The healthcare waste management practices about segregation, collection, transportation and disposal at the source is crucial to decrease in quantity. Generally unselective handling and disposal of healthcare wastes is a concern.

Anti-cancer drug waste disposal practices and wastewater management in hospitals: A Lebanese survey.

INTRODUCTION: To achieve continuous environmental sustainability and protect the population's health, healthcare waste (in liquid or solid form) needs appropriate management and suitable treatment strategies before its final disposal in the environment in order to reduce its adverse impacts. This study aims to identify disparities in the waste management of anti-cancer drugs and the wastewater generated in Lebanese hospitals. METHODS: Three questionnaires were designed to evaluate the level of knowledge, awareness and experience of hospital personnel regardless of their job levels. Data was collected in December 2019 from three departments of each participating hospital: pharmacy, oncology and maintenance departments. A descriptive analysis was conducted to summarise the survey results. RESULTS: The results revealed a lack of transparency and awareness of the participants, with a high frequency of 'prefer not to say' responses when asked about the disposal methods of anti-cancer drugs and with only 5.7% of the participants in the pharmacy department sharing their disposal procedures. The same perception was deduced regarding hospitals' wastewater treatment, where responses were often contradicting, preventing making assumptions about the fate of hospital wastewater. CONCLUSION: The results of this survey support the need to establish a more comprehensive waste management programme in Lebanon that would be maintained through regular training and supervision.
