UNASSIGNED: Global evidence has linked unused medications and their inappropriate disposal to adverse health, economic, environmental, and ethical impacts. However, such evidence is scarce in Qatar. This study explored patients\' knowledge and attitude toward unused medications and their practices toward medication supply and disposal (KAP) in Qatar.Materials and methods.
UNASSIGNED: A cross-sectional survey using a pretested questionnaire was performed between February 2020 and October 2020. Descriptive statistics, Man Whitney U, and Kruskal-Wallis Rank-Sum tests were applied. The Chi square test assessed the association between socio-demographic characteristics and KAP scores. Characteristics that were found significantly associated with KAP (i.e., p-values <0.05) were further included as predictor variables in the multiple linear regression model.
UNASSIGNED: All items pertaining to patients\' knowledge were found to be good (mean score > 3), except for \"awareness of unwanted medication return policy\" (mean score < 3), i.e., the lowest level of patient agreement (31 %) (median (M) = 3, Interquartile Range (IQR) = 3). Their attitude was generally good (mean score > 3). Conversely, their practice toward medication supply was poor (mean score < 3). Possible future use was the most reported reason (79 %) for keeping medications at home, and home trash was the most widely disposing place of unused ones (76 %). Knowledge was significantly higher among non-laborers and other occupations than among patients with no work (p < 0.001) and (p = 0.005), respectively. The attitude was significantly lower among patients with healthcare providers (HCPs) in their household than among those without (p = 0.001). Practices were also significantly lower among those aged 40-49 years and those with HCPs in their household than those aged 18-29 years (p = 0.012) and those without HCPs, (p < 0.001), respectively.
UNASSIGNED: Overall, patients\' knowledge and attitude toward unused medications seem good, while their practices toward medication supply and disposal are bad. To mitigate the health, economic, and environmental impacts of unused medications, interventions including rationalizing drug supply, use, disposal, prescribing, manufacturing, and promotion are recommended.

1. The production of chicken meat has resulted in high volumes of byproducts, such as feathers, bones, skin, viscera, and feet. The structure of feathers is one of the most complex among vertebrates, with a central axis and lateral filamentary structures, providing rigidity, lightness, and flexibility. Chicken feathers are composed of proteins, lipids, and water, with the highest protein content, especially keratin, which is responsible for the material\'s rigidity.2. Industries still make little use of feathers, which are generally intended for the production of flour or organic fertilisers. These are low added value products, and discarded feathers can harm the environment.3. Keratin extraction techniques and resulting protein hydrolysates have been studied in chicken feathers. Acid, alkaline or enzymatic hydrolysis is the most commonly used method for obtaining molecules with functional properties such as antioxidant, antimicrobial, antihypertensive and antidiabetic activity.4. The development of keratin-based biodegradable films represents an area of interest for reducing the economic and environmental impacts caused by inappropriate disposal of feathers.

Characterization and evaluation of hazardous spent V2O5-WO3/TiO2 catalysts are critical to determining their treatment or final disposal. This study employs a thermal approach to simulate the preparation of spent catalysts derived from commercial V2O5-WO3/TiO2 catalysts and investigate the structure-activity relationship of the carrier changes during the deactivation process. The results indicate that the catalyst carrier undergoes two processes: an increase in grain size and a transformation in crystal structure. Both structural and catalytic investigations demonstrate that the grain size for catalyst deactivation is 24.62 nm, and the formation of CaWO4 occurs before the crystalline transformation. The specific surface area is susceptible to an increase in grain size. The reactions of selective catalytic reduction involve the participation of both Brønsted acid and Lewis acid sites. The deactivation process of the carrier initially affects Brønsted acid sites, followed by a reduction in Lewis acid sites, resulting in a decline in NH3 adsorption capacity and oxidation. Correlation analysis reveals that changes in the physicochemical properties of the catalyst reduce the NO conversion, with the order being The grain size > Total acid amount > The surface area. It is recommended to recycle the spent catalyst if the carrier grain size is less than 25 nm. The findings of this investigation contribute to expanding the database for evaluating and understanding the physicochemical properties of spent catalysts for disposal.

Introduction The environment, healthcare services, and public safety can all be directly impacted by improper drug storage and disposal practices. It is unknown whether parents store drugs at home in accordance with recommended storage guidelines, despite the fact that storage conditions are strictly regulated and monitored at every stage of the drug supply chain prior to drug dispensing. Therefore, it is crucial to dispose of medications properly and store them at home to avoid the consequences. Aim The purpose of this study was to evaluate the drug storage safety measures used by parents to prevent unintentional drug poisoning in children. Methodology A structured questionnaire was used to conduct a cross-sectional, interview-based study on home medication storage, attitudes, and disposal practices between October 2023 and January 2024. We recruited parents who visited primary healthcare centers or pediatric clinics using a convenience sampling technique. Results All of the 353 returned questionnaires were valid for data entry and analysis. The mean age of the parents was 35.1 ± 11.9 years old and more than half of them 229 (64.9%) have bachelor\'s degrees. The majority of drugs (271, 88.6%) were stored in the fridge, followed by bedrooms (26.8%). The medication classes that were stored the most frequently were analgesics (92.2%) and antihistamines (62.1%). The majority of parents (214, 69.9%) kept medications above adult eye level, even though only 28% did not keep them in safe and secure locations like locked drawers or boxes. Eighty percent (80%) disposed of unwanted medicines by throwing them in the trash, and only 10 (2.8%) returned them to the pharmacy.  Conclusions Drug storage at home encourages self-medication, which has a number of negative effects. Over time, there has been an increase in the use of medications due to a rise in people\'s health-seeking awareness and behavior on a global scale. Therefore, this study may be used as a guide by national policy-makers for pharmaceutical disposal and storage management. Moreover, it might help in raising public awareness of the importance of pharmacists in the society and the safe handling and storage of medications at home.

Municipal solid waste (MSW) management systems play a crucial role in greenhouse gas (GHG) emissions in China. Although the government has implemented many policies to improve the MSW management system, the impact of these improvements on city-level GHG emission reduction remains largely unexplored. This study conducted a comprehensive analysis of both direct and downstream GHG emissions from the MSW sector, encompassing sanitary landfill, dump, incineration, and biological treatment, across 352 Chinese cities from 2001 to 2021 by adopting inventory methods recommended by the Intergovernmental Panel on Climate Change (IPCC). The results reveal that (1) GHG emissions from the MSW sector in China peaked at 70.6 Tg of CO2 equiv in 2018, followed by a significant decline to 47.6 Tg of CO2 equiv in 2021, (2) cities with the highest GHG emission reduction benefits in the MSW sector were historical emission hotspots over the past 2 decades, and (3) with the potential achievement of zero-landfilling policy by 2030, an additional reduction of 203.7 Tg of CO2 equiv is projected, with the emission reduction focus toward cities in South China (21.9%), Northeast China (17.8%), and Southwest China (17.3%). This study highlights that, even without explicit emission reduction targets for the MSW sector, the improvements of this sector have significantly reduced GHG emissions in China.

UNASSIGNED: Diabetes Mellitus is a long duration disease, and if a person with diabetes is infected with a blood-borne infectious disease and proper syringe disposal practices are not followed, they run the danger of transmitting the infection to others for a very long period. Whereas fewer research has been done in China on the handing of sharp objects at home. Therefore, there is a need to translate and localize the Knowledge-Attitude-Practice Questionnaire regarding sharp disposal for diabetic patients to assess the current level of patient knowledge, attitudes, and practices and to improve the basis for promoting safe sharps handling practices.
UNASSIGNED: This investigation was a cross-sectional study. The Knowledge-Attitude-Practice Questionnaire regarding sharp disposal was localized and debugged and tested for reliability and validity, and then 334 patients were investigated by General Characteristics Questionnaire, Knowledge- Attitude-Practice Questionnaire regarding sharp disposal, and the influencing factors of practice level regarding sharp disposal of patients were analyzed.
UNASSIGNED: The Cronbach\'s α value of the attitude section was 0.864 and the content validity index was 0.923. The knowledge and practice sections are in line with continental language conventions and are easy to understand without any ambiguity. The majority (52%) of the participants had poor knowledge and a neutral attitude toward disposing of sharp objects. Sharps disposal practices among diabetes mellitus patients were poor since about 90% of patients dispose of their used sharps directly into the household waste. Furthermore, we found that level of education, knowledge and attitude were the major predictors of practices regarding sharps disposal among diabetic patients (R 2 = 0.573, p < 0.001).
UNASSIGNED: The Chinese version of the Knowledge-Attitude-Practice Questionnaire regarding sharp disposal has applicability in China. In China, current practice of disposing used sharps is improper. Additionally, the majority of the subjects had low levels of knowledge and attitudes. To raise awareness and encourage diabetic patients to follow appropriate sharps disposal practices, there needs to be ongoing education and a locally tailored safe sharp disposal alternative accessible.

With ever-improving social and medical awareness about menstrual hygiene in India, the demand for sanitary napkins has increased significantly. The utilization of high-quality and environment-friendly raw materials to produce these pads is further supporting the growth of the market. However, with improving demand and usage, the need for proper disposal techniques becomes more relevant, since all of these pads get contaminated with human blood which makes them a biohazard and can cause significant damage to human health and the environment. One sanitary pad takes around 800 years to degrade naturally and the plastic and super absorbent polymers (SAPs) in sanitary pads are non-biodegradable and can take multiple decades to degrade. Waste management technologies such as pyrolysis, gasification, and resource recovery can be adopted to manage tons of sanitary waste. Currently, sanitary waste treatment mainly focuses on landfilling, incineration, and composting, where biohazard wastes are mixed with tons of solid waste. Disposable sanitary pads have a high carbon footprint of about 5.3 kg CO2 equivalent every year. Innovative solutions for sanitary pad disposal are discussed in the manuscript which includes repurposing of derived waste cellulose and plastic fraction into value-added products. Future aspects of disinfection strategies and value addition to waste cellulose recovered from napkins were systematically discussed to promote a circular economy.

Used face masks are hazardous waste and must be discarded immediately upon removal. Instead of throwing used masks into the disposal bin, disinfecting the masks is essential to break the chain of infection spread. The development of this device was attempted for COVID-19 management, with the following focus: (1) solution which have sufficient science background established so that extensive experimental validation need not be attempted during the lockdown period in India. (2) Provide solution which could be replicated with local resources and minimum material movement. Therefore, in response to the pressing societal demand we designed, prototyped, verified and validated an UV-C-based multipurpose disinfection device. The device after safety and efficacy evaluation as per the Indian Council of Medical Research (ICMR) guidelines for novel COVID-19 solutions, received Central Drugs Control Standard Organization (CDSCO) registration as non-notified medical device for commercialization.

The origin of the novel human coronavirus (SARS-CoV-2) and its potential for harm increased face mask and medical waste in the environment, thereby necessitating the urgent prevention and control of the pandemic. The article estimates the face mask and medical waste generation in Asia during the pandemic to convince the waste management and scientific communities to find ways to address the negative impact that the waste disposal has on the environment. Standardisation, procedures, guidelines and strict implementation of medical waste management related to COVID-19, community habitats and public areas should be carefully considered to reduce pandemic risks in hospitals, as proper medical waste disposal effectively controls infection sources.

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.
