BACKGROUND: Healthcare waste is any waste generated by healthcare facilities that is considered potentially hazardous to health. Solid healthcare waste is categorized into infectious and non-infectious wastes. Infectious waste is material suspected of containing pathogens and potentially causing disease. Non-infectious waste includes wastes that have not been in contact with infectious agents, hazardous chemicals, or radioactive substances, similar to household waste, i.e. plastic, papers and leftover foods. This study aimed to investigate solid healthcare waste management practices and develop guidelines to improve solid healthcare waste management practices in Ethiopia. The setting was all health facilities found in Hossaena town.
METHODS: A mixed-method study design was used. For the qualitative phase of this study, eight FGDs were conducted from 4 government health facilities, one FGD from each private health facility (which is 37 in number), and forty-five FGDs were conducted. Four FGDs were executed with cleaners; another four were only health care providers because using homogeneous groups promotes discussion. The remaining 37 FGDs in private health facilities were mixed from health professionals and cleaners because of the number of workers in the private facilities. For the quantitative phase, all health facilities and health facility workers who have direct contact with healthcare waste management practice participated in this study. Both qualitative and quantitative study participants were taken from the health facilities found in Hossaena town.
RESULTS: Seventeen (3.1%) health facility workers have hand washing facilities. Three hundred ninety-two (72.6%) of the participants agree on the availability of one or more personal protective equipment (PPE) in the facility \'\'the reason for the absence of some of the PPEs, like boots and goggles, and the shortage of disposable gloves owes to cost inflation from time to time and sometimes absent from the market\'\'. The observational finding shows that colour-coded waste bins are available in 23 (9.6%) rooms. 90% of the sharp containers were reusable, and 100% of the waste storage bins were plastic buckets that were easily cleanable. In 40 (97.56%) health facilities, infectious wastes were collected daily from the waste generation areas to the final disposal points. Two hundred seventy-one (50.2%) of the respondents were satisfied or agreed that satisfactory procedures are available in case of an accident. Only 220 (40.8%) respondents were vaccinated for the Hepatitis B virus.
CONCLUSIONS: Hand washing facilities, personal protective equipment and preventive vaccinations are not readily available for health workers. Solid waste segregation practices are poor and showed that solid waste management practices (SWMP) are below the acceptable level.

UNASSIGNED: Almost 70% of women residing in urban areas and 48% of women in rural areas use sanitary napkins in India. According to menstrual health alliance India (MHAI), single sanitary pad will take about 500-800 years to decompose as the plastic used in manufacturing is nonbiodegradable and causes severe noxious effects contributing to global warming through the production of planet warming fuels which eventually have severe impact on environment sustainability. Hence, the study was undertaken to contribute the evidence for the \"Clean and Green India\".
UNASSIGNED: To know the perception and practice of disposal of sanitary napkins among young college-going females in India.
UNASSIGNED: A cross-sectional study was conducted throughout the country employing a self-administered questionnaire using a survey link sent through social media. Data collected were analyzed and interpreted using SPSS version 20.0.
UNASSIGNED: The study population comprised 484 young college girls with a mean age of 20.92 ± 1.86 years and 96.9% of them are using sanitary napkins as menstrual absorbent aids. The most common method employed for the disposal of sanitary napkins was dumping them in the bin (87.4%). About 63.2% of them had no knowledge about sanitary napkin-burning machines. Around 92% think that improper disposal of sanitary napkins can cause health problems.
UNASSIGNED: The findings from the study revealed that a significant number of women were practicing noneco-friendly disposal methods and menstrual hygiene aids which are a bane to the ecosystem. Study warrants the education and training of females to achieve a green and clean sustainable India.

OBJECTIVE: Unsafe opioid-related practices can lead to abuse, diversion, and accidental overdoses. In this study, we aimed to describe the patterns and beliefs regarding the storage, disposal, and use of opioids among Chinese patients with cancer in their home settings, which remain unclear.
METHODS: A multicenter cross-sectional survey was conducted in Hubei Province from October 2022 to June 2023. We collected information on the storage, disposal, and use of opioids among cancer pain inpatients in the oncology department. Logistic regression was used to estimate the factors associated with unsafe disposal and use of opioids.
RESULTS: The survey included 221 patients with a median age of 62 years. Only 3.2% stored their opioids under lock and key, and 49.8% were unaware of proper disposal methods. Nearly one-fifth (19.5%) reported having received information on the safe storage (14.0%) and/or disposal (10.0%) of opioids. A total of 44.3% reported unsafe use by sharing (1.8%), losing (4.1%), or taking opioids at a higher dose than prescribed (42.5%). Patients who did not receive information on the safe disposal of opioids (OR = 4.57, P = .0423), had a history of alcohol use (OR = 1.91, P = .0399), and used opioids other than morphine (OR = 2.31, P = .0461) had higher odds of unsafe disposal practices. Individuals with an associate degree/bachelor\'s degree or above were less likely to dispose of (OR = 0.36, P = .0261) and use (OR = 0.31, P = .0127) opioids unsafely.
CONCLUSIONS: A significant proportion of Chinese patients with cancer exhibit unsafe practices in the storage, disposal, and use of opioids. The study highlights an urgent need for implementing routine education programs and drug \"take-back\" initiatives to improve opioid-related practices.

UNASSIGNED: The COVID-19 pandemic had an enormous impact on people\'s quality of life worldwide. Appropriate use of facemasks is an important checkpoint in containing the spread of infection, which was believed to provide the desired level of protection and preserve the community. Given the relative novelty of facemask use in the general population, it is imperative to prioritize the promotion of appropriate facemask utilization and identify factors that may contribute to poor adherence.
UNASSIGNED: This study assessed the factors that determined facemask use among the public.
UNASSIGNED: A cross-sectional questionnaire-based study was conducted among the residents of the Kingdom of Saudi Arabia between November 2020 and January 2021. The current study explored the factors such as demographic characteristics influencing the knowledge and practice of proper use of facemasks. The study included a total of 198 participants. The results were derived through binomial logistic regression analysis to determine the relationship between the demographic characteristics and responses.
UNASSIGNED: The key findings of the study which are crucial in developing targeted intervention strategies to enhance the responsible use and disposal of facemasks are gender, income and employment. A significant difference was found between male and female participants regarding a positive approach to using facemasks, such as washing their hands (P = 0.042). In addition, homemakers differed significantly from students, regarding the correct usage of facemasks (P = 0.026). The study participants were aware that hand hygiene is essential when putting on and removing facemasks. Despite wearing facemasks properly, adult participants possessed less knowledge about the hazards of reusing facemasks and appropriate disposal (OR = 0.202, 95% CI [0.032-1.298]).
UNASSIGNED: The present research identified gender, income, and employment as the primary attributes that play a pivotal role in the formulation of focused intervention tactics aimed at improving the cautious use and appropriate disposal of facemasks. It is essential to implement nationwide awareness activities, such as information campaigns, to enhance knowledge. Health authorities should establish a functional infrastructure for the collection and disposal of used facemasks by the general public, starting with the dissemination of knowledge. Moreover, the results of the present study have significant implications for health preventive programs aimed at preparing for future pandemics, since they highlight the specific demographic groups that should be prioritized in the development of such policies. Furthermore, it is advisable to integrate these interventional initiatives with national health polices to promote preparedness for handling future pandemics.

BACKGROUND: The improper disposal of pharmaceutical preparations substantially threatens human health and environmental safety. Pharmacists are responsible for properly disposing of unwanted medications and educating patients about how to do so themselves. This study aimed to assess community pharmacists\' knowledge, determine their views on how to dispose of unwanted pharmaceuticals, and assess the extent to which they realize that it is their responsibility to guide patients toward the safe disposal of expired medications.
METHODS: A descriptive cross-sectional study was conducted between December 2021 and April 2022 among 400 practicing pharmacists who were chosen to participate by random cluster sampling. Community pharmacists\' practices, awareness, and beliefs about disposing of unused drugs were evaluated. The Statistical Package for Social Sciences (IBM-SPSS) version 21 was used for data entry and analysis.
RESULTS: Of 400 pharmacists, 348 stated that they did not participate in courses on the safe disposal of unwanted medications. Disposal of drugs in the garbage, an unsafe method, was very frequently recommended by pharmacists to patients, especially regarding inhalers, antibiotics, hormonal drugs, and solid and semisolid drugs. However, many pharmacists advised patients to return their hormonal, category B, and category C drugs to the pharmacy. A total of 61.3% of pharmacists agreed and 26% strongly agreed that unsafe disposal of drugs negatively affects the environment. A total of 54.3% of the participants agreed that improper disposal of antibiotics might be a reason for increased antimicrobial resistance, and 54.5% of them agreed that improper disposal of hormonal drugs might contribute to the development of certain cancers. A total of 80.3% of the participants perceived that most unwanted drugs in pharmacies were those returned from patients. A total of 97.3% of the participants supported establishing a drug disposal system, with 77.5% choosing to have the district health board responsible for funding this system. A total of 48.5% of the participants indicated that a lack of education and awareness on the issue of getting rid of unused drugs constitutes a challenge to the safe disposal of medicines, and 66% of them said that a lack of law enforcement constitutes another challenge. A total of 95.5% of the participants agreed or strongly agreed that good training for health sector workers and organizing workshops to develop knowledge on this subject would improve practices. A total of 93.3% supported distributing educational brochures, and 92.8% supported placing special containers in every pharmacy to collect unwanted drugs.
CONCLUSIONS: Most pharmacists in our study returned drugs to manufacturing companies and stores, and few followed the correct methods of incineration and return of drugs to the Ministry of Health. Current data emphasize the issue of improper disposal of medicine in Palestine and the need for improved education among healthcare workers.

Dredging is one of the most effective methods for inhibiting the endogenous contamination of natural lakes. However, both the amount and the scope of dredging will be restricted if the disposal of the dredged sediment incurs considerable environmental and economic costs. The use of dredged sediments as a post-mining soil amendment for mine reclamation benefits both sustainable dredging and ecological restoration. This study incorporates a field planting experiment with a life cycle assessment to confirm the practical effectiveness of sediment disposal via mine reclamation, as well as its environmental and economic superiority over other alternative scenarios. The results show that the sediment offered plentiful organic matter and nitrogen for mine substrate, stimulating plant growth and increasing photosynthetic carbon fixation density, followed by enhanced plant root absorption and an improved soil immobilization effect on heavy metals. A 2:1 ratio of mine substrate to sediment is recommended to significantly promote the yield of ryegrass while reducing levels of groundwater pollution and soil contaminant accumulation. Due to the significant reduction in electricity and fuel, mine reclamation had minimal environmental impacts on global warming (2.63 × 10-2 kg CO2 eq./kg DS), fossil depletion (6.81 × 10-3 kg oil eq./DS), human toxicity (2.29 × 10-5 kg 1,4-DB eq/kg DS), photochemical oxidant formation (7.62 × 10-5 kg NOx eq./kg DS), and terrestrial acidification (6.69 × 10-5 kg SO2 eq./kg DS). Mine reclamation also had a lower cost (CNY 0.260/ kg DS) than cement production (CNY 0.965/kg DS) and unfired brick production (CNY 0.268/kg DS). The use of freshwater for irrigation and electricity for dehydration were the key factors in mine reclamation. Through this comprehensive evaluation, the disposal of dredged sediment for mine reclamation was verified to be both environmentally and economically feasible.

Plastics and microplastics have been quantified and characterised at disposal sites of abandoned fishing boats and along the high-water line (HWL) of a fish landing centre in Chellanam, India. Fibreglass-reinforced plastic (FRP) made a greater contribution to the plastic pool at the disposal sites (~ 4.5 n m-2 and 18 g m-2) than the HWL (~ 0.25 n m-2 and < 1 g m-2) and was an abundant component of the microplastic pool at the former. Infrared analysis of micro-sized FRPs revealed various resins (e.g., alkyd, polyester, epoxy), while X-ray fluorescence analysis of the painted surfaces of meso-sized FRPs returned variable concentrations of copper and lead. Concentrations of Pb were high enough to contaminate sand up to ~400 mg kg-1. The relatively high density of FRP and its association with glass fibres and metal-bearing paints results in particles with potentially very different fates and toxicities to more \"conventional\" (non-composite) thermoplastics.

The oil and gas industries are the largest producers of NORM wastes that are continuously generated during production and extraction activities. In addition, an increasing trend is observed in waste production worldwide due to the decommissioning of oil platforms. The problem is that most of these wastes are in activity concentration levels above the exemption and the clearance limits and are being accumulated in storage sites because no repositories exist in Brazil for NORM wastes generated by oil industries. There are regulations for radioactive wastes and for the licensing of repositories for managing wastes with low and intermediate levels of radiation but the current regulations apply only to packaged wastes. Therefore an initial radiological assessment was carried out with the RESRAD-OFFSITE code to show that bulk NORM wastes (not packaged wastes) could be disposed of in repositories near the surface without causing additional risk to the public above the criteria used. The results can also support decision-making by the Regulatory Authority to change the current regulations and allow for the disposal of wastes in bulk form.

Background: Patients with life-limiting cancers are commonly prescribed opioids to manage pain, dyspnea, and cough. Proper prescription opioid disposal is essential to prevent poisonings and deaths. Objective: We examined opioid disposal practices of patients referred to a Canadian outpatient palliative care clinic (OPCC). The primary objective was to determine the prevalence of OPCC patients who did not routinely dispose their opioids. The secondary objectives were to examine their methods of opioid disposal and to identify patient characteristics associated with routine disposal of opioids. Design and Setting: This cross-sectional study involved a retrospective chart review of new, adult patients who were seen in a Canadian OPCC (September 2018-August 2019) and completed a survey about opioid-related constructs: source of prescriptions, use, storage, disposal, and knowledge about associated harms. Results: Among the 122 study participants, half (58/111, 52.3%) reported that they did not routinely dispose their opioids. The most common method of disposal was by giving them to pharmacists (69/88, 78.4%). Cannabis use (odds ratio [OR]: 3.7, 95% confidence interval [CI]: 1.1-11.8) and neuropathic medication use (OR: 3.0, 95% CI: 1.2-7.2) were positively associated with routine disposal of opioids. Conversely, reports of an increased amount of opioid use in the past six months were negatively associated with routine disposal of opioids (OR: 0.38, 95% CI: 0.16-0.88). Conclusion: The high prevalence of people with life-limiting illnesses who do not routinely dispose their opioids requires increased attention. Interventions, such as education, are needed to reduce medication waste and opioid-related harms.

Most insulin injections for people with diabetes are administered at home, thus generating many used needles. Unsafe disposal of these at-home needles can lead to needle stick injuries, blood-borne disease transmission, and environmental contamination. Previous studies have shown varying results on the prevalence of and factors associated with safe sharps disposal practices of people with diabetes.
To assess the prevalence of and the factors associated with the safe disposal of used insulin needles among patients with diabetes.
We collected data from 271 insulin-using patients at a tertiary care hospital in China. A self-designed instrument was used to assess sociodemographic data, disease- and treatment-related characteristics, sharps disposal practices, education on diabetes self-management and sharps disposal, and awareness of the potential risks associated with unsafe sharps disposal. Multivariate logistic regression analysis was used to explore factors associated with safe sharps disposal practices.
Only 10.3% (28/271) of participants disposed of used at-home insulin needles in a safe manner, and 14.8% (45/271) of participants had received previous instruction on sharps disposal. Previous sharps disposal instruction (AOR = 4.143, 95% CI = 1.642-10.450) and awareness of the risk of blood-borne pathogen transmission (AOR = 3.064, 95% CI = 1.332-7.046) were associated with safe disposal of used insulin needles.
In our study, the prevalence of safe sharps disposal practices was low, and a minority of respondents had received previous instruction on sharps disposal. Participants who had previously received instruction and were aware of the risk of blood-borne pathogen transmission were more likely to handle sharps safely. Our study findings suggest that health care professionals should pay attention to sharps disposal practices of patients with diabetes and conduct diabetes education programs that include information on safe sharps disposal methods and potential hazards of unsafe sharps disposal.
