RESUMO
BACKGROUND: Inefficient supply chain management within the US healthcare industry results in significant financial and environmental impact. Unopened medical supplies may routinely be discarded in the Emergency Department (ED), contributing as a source of unnecessary medical waste. OBJECTIVES: Quantify the financial and environmental impact of unopened medical supplies that are routinely discarded in two EDs. METHODS: The study utilized a waste audit of collection bins targeting unopened medical supplies that would have otherwise been discarded. Associated financial cost was calculated using data from the purchasing department and from an online search. End-of-life (EOL) environmental impact was calculated using the M+ Wastecare calculator. A lifecycle analysis was performed on a supplier-packaged intubation kit, which the study identified as a significant source of waste. RESULTS: High volumes of unused, unopened supplies (143.48 kg) were collected during the study period with a yearly extrapolated value of 1337 kg. Purchasing costs over 44 days at Hospital A and 37 days at Hospital B for these items amounted to $16,159.71 across both sites with a yearly extrapolated value of $150,631.73. Yearly extrapolated EOL impact yielded 5.79 tons per year of CO2eq. Components from supplier-packaged intubation kits were found to contribute to 45.2% of collected items at one site which purchased them. Lifecycle analysis of an intubation kit yields 23.6 kg of CO2eq. CONCLUSION: This study demonstrates that the disposal of unopened medical supplies contributes a significant source of financial and environmental waste in the ED setting. The results continue to support the trend of procedure kits generating significant environmental and financial waste.

INTRODUCTION: Poor clinical waste management and its effect on the environment is an increasingly recognised concern for global healthcare systems. Approximately two thirds of waste produced in healthcare is from the operating theatre. In the Republic of Ireland, an estimated 580,977 tonnes of hazardous waste was produced in 2019. The cost of incineration of this hazardous waste is approximately 2,125 per tonne and 935 per tonne for sterilisation. Pollution from incineration is substantial and harmful. METHODS: A literature review was performed on the topic of hospital waste management, specifically looking at the Republic of Ireland. A comparison could then be drawn between Ireland, Europe and the United States of America. Observation of our current operating theatre environment and practices were carried out. DISCUSSION: An increased focus towards sustainability and reusable equipment means that there is potentially a decreased amount of waste for disposal, but an increase in the process of sterilisation. Approximately 66% of healthcare related waste is inappropriately contaminated, meaning that significant savings are possible if correct segregation and recycling were to occur. An increase in the amount of bins, identification labels above bins and education of staff results in an increased likelihood of successful segregation of waste. Clear and concise hospital guidelines of what is considered hazardous versus non-hazardous waste will decrease the amount of inappropriately disposed items.

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.

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.

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.

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.

Medical waste incineration fly ash (MWI FA) is classified as a hazardous solid waste. Therefore, the development of recycling technologies to convert MWI FA into useful products is necessary and challenging. In this study, we developed a sustainable approach for preparing a catalyst through the pyrolysis of water-washed MWI FA (WW FA-x, where x corresponds to the pyrolysis temperature). Subsequently, it was applied as a potent peroxydisulfate (PDS) activator to remove tetracycline (TC) from water. The results showed that the WW FA-800 exhibited remarkable adsorption performance as well as highly efficient catalytic activation of PDS, with a 115 mg/g maximum TC adsorption capacity and 93.5% (reaction kinetic rate = 315 µmol/g/h) TC removal within 60 min. A synergistic effect was achieved by adsorption and PDS activation. TC degradation was primarily driven by non-radical (1O2 and electron transfer) processes. WW FA-800 possesses multiple active sites, including defects, π-π*, O-CO groups, Fe0, and Cu(I). Three possible pathways for TC decomposition have been proposed, with the majority of intermediates exhibiting less toxicity than TC. Furthermore, the WW FA/PDS system exhibited an excellent anti-interference ability, and universality in the degradation of various organic contaminants. Notably, energy consumption was minimal, approximately 2.80 kWh/(g·TC), and the leachability of heavy metals in the WW FA-800 was within acceptable limits. This study provides a MWI FA recycling route for the development of highly active catalysts.

PURPOSE OF THE REVIEW: Wastewater is a term used to describe water that has undergone degradation in quality owing to anthropogenic activities or natural processes. Wastewater encompasses liquid waste originating from academic institutions, households, agricultural sector, industries, mines and hospitals. Hospital wastewater contains potentially hazardous substances including residues of pharmaceuticals, radioisotopes, detergents and pathogens, with detrimental impacts to the environment and human health. Nevertheless, studies related to hospital waste management are limited in Africa, particularly in Southern Africa. This research offers an overview of aspects surrounding hospital wastewater in Southern Africa, focusing on Zimbabwe. Already published and grey literature was reviewed to compile the paper. RECENT FINDINGS: Number of patients, nature of medical services offered and hospital size influences generation of hospital wastewater. Partially and non-treated hospital wastewater is managed together with municipal wastewater. Management of hospital wastewater is impeded by shortage of resources, lack of co-ordination among responsible authorities and ineffective legal framework enforcement, among other challenges. Inappropriate hospital wastewater management results in environmental contamination, causing human ailments. Attainment of sustainable hospital wastewater management requires clearly defined and enforced legislation, collaboration of accountable stakeholders, sufficient resources and enhanced awareness of involved stakeholders. Application of technologies that uphold recycling and reuse of wastewater is essential to reach Sustainable Development Goals, Zimbabwe Vision 2030 and National Development Strategy 1 targets, particularly those dealing with environmental protection while upholding human health.

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.

OBJECTIVE: To unveil the meanings that nursing professionals attribute to practices related to waste management in health services, within the hospital context. 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.

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.

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.

PURPOSE OF REVIEW: The healthcare sector has a substantial environmental footprint, and the delivery of anesthesia contributes significantly. Inhaled anesthetics themselves are potent greenhouse gases, unused intravenous medication exert toxic effects on the environment, and the increasing reliance on single-use devices has led to an ever-growing amount of solid waste produced in operating rooms. This review discusses many of these environmental impacts and suggests practices to mitigate the environmental footprint of anesthetic practice. RECENT FINDINGS: The choice of anesthesia maintenance has significant environmental implications, with nitrous oxide and desflurane having the highest carbon footprint of all anesthetic agents. Using low fresh gas flows and supplementing or replacing inhalational agents with propofol leads to a significant reduction in emissions. Many intravenous anesthetic agents pose a risk of environmental toxicity, and efforts should be made to decrease medication waste and ensure appropriate disposal of unused medications to minimize their environmental impacts. Additionally, consideration should be given to replacing single-use devices in the operating rooms with reusable alternatives that are often both environmentally and economically superior. And solid waste generated in the operating room should be segregated thoughtfully, as processing regulated medical waste is a highly energy-intensive process. SUMMARY: Significant opportunities exist to improve the environmental footprint of anesthesia practice, and with the rapidly worsening climate crisis, the importance of implementing changes is greater than ever.

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.

BACKGROUND AND PURPOSE: The rise in hip and knee arthroplasty for osteoarthritis requires addressing healthcare system pollution to support Ireland's climate change goals. This research aimed to quantify waste generated and determine environmental and economic impacts to promote sustainable strategies in joint arthroplasty and shed light on the suboptimal waste management practices. METHODS: The study was conducted at National Orthopaedic Hospital Cappagh (NOHC), measuring waste generated during hip and knee arthroplasty. Clinical, domestic, and recycled waste weights were recorded, including the segregation of Central Sterile Supply Department (CSSD) Blue Wrap waste in ten operations. Kilograms of carbon dioxide emissions (kgCO2e) and disposal costs were calculated. RESULTS: In a sample of 100 joint arthroplasty operations, the study found that revision knees produced 23.58 âkgCO2e per case, revision hips 23.50 âkgCO2e, primary knees 15.82 âkgCO2e, and primary hips 14.64 âkgCO2e. CSSD Blue Wrap contributed on average 13.5% of OT waste. Extrapolating these findings to the estimated number of joint arthroplasties performed in 2022 âat NOHC (1556 hip and knee joint arthroplasties), the emissions were estimated to be 24,576 kgCO2e, with the cost of disposal up to 29,228. Strategies to mitigate this waste have been identified and proposed. CONCLUSION: The research aimed to address the environmental impact of orthopaedic joint arthroplasties, offering strategies to reduce waste generation, carbon emissions, and cost. Utilising our methodology to calculate greenhouse gas emissions will empower sustainability offices to conduct their own waste audits and implementing our strategies for waste management practices can help minimise environmental waste.

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.

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.

PURPOSE OF REVIEW: This review aims to provide an update on the results of studies published in the last two years involving the development of sustainable practices in hospital and operating theaters (OT). RECENT FINDINGS: Recently, many studies evaluated various initiatives to better understand the environmental impact of the OT but also to minimize its environmental impact. Many trials evidenced the positive impact of the instrument's reuse using an appropriate reprocessing procedure. Better waste segregation is associated with a reduction of produced waste and contributes to a significant reduction in CO 2 equivalent emissions. Regarding anaesthetic gas, Desflurane is known to have the worst environmental impact and the majority of the study evidenced that its reduction permits to drastically reduce greenhouse gas emission of the OT. SUMMARY: Greening the OT necessitates climate-smart actions such as waste reduction, the improvement of reusable instruments, recycling of our waste and better anaesthetic gas management. Within the last two years, many efforts have been made to reduce and better segregate waste produced in the OT and also to better understand the environmental impact of disposable and reusable devices.

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.

INTRODUCTION: Hospitals and the healthcare system contribute significantly to global warming, due to the energy use, water use and waste produce going directly to landfill. The operating theatre environment contributes to 70% of all hospital waste, and a proportion of this is due to unused surgical supplies, such as those stocked but never used as they go past their use-by date. AIM: To evaluate how use-by dates are identified and assigned to surgical equipment, and if there are opportunities to re-use, or re-sterilise this equipment in order to reduce waste from the operating theatre environment. RESULTS: Use-by dates are assigned to ensure sterility and longevity of the device, and are assigned based on risk analysis, retrospective and prospective assessment. Incineration is the mainstay of disposal of unused medical devices, but there are alternative options such as re-processing in specific circumstances. CONCLUSION: A large volume of hospital waste is due to operating theatres, and there is movement towards developing more sustainable methods of dealing with expired surgical equipment. This is however in the early stages, with further research required to confirm if these methods will be safe for patients, and beneficial to the environment.
