“…Waste generated within healthcare facilities encompasses a wide range of materials, each carrying varying degrees of risk. Proper waste segregation is essential to categorize waste into distinct streams, such as infectious, hazardous, and general waste [ 36 ]. Trained personnel handled hazardous waste, including sharp objects and infectious materials, using appropriate personal protective equipment (PPE).…”

Biomedical waste management (BMWM) in India poses significant challenges that demand thorough examination and strategic interventions. As the country's healthcare sector expands rapidly, proper management of biomedical waste becomes increasingly critical to safeguarding public health and environmental integrity. Biomedical waste, encompassing industrial waste, hospital waste, and waste from other healthcare facilities, poses a heightened risk of infection and injury compared to any other form of waste. A lack of understanding regarding safe medical waste disposal practices can be hazardous to one's health as well as the environment. To improve waste management practices in the country, we can suggest effective strategies and recommendations by developing a deeper understanding of the current situation. To manage medical waste effectively, healthcare professionals must be knowledgeable about and have experience with this process. This evaluation study provides a comprehensive overview of current BMWM methods in India, shedding light on the benefits, drawbacks, challenges, and areas for improvement in the healthcare waste management system. Several important facets of BMWM were highlighted by the literature research, including waste segregation, treatment techniques, and disposal options, as well as compliance and regulatory frameworks.

“…Healthcare facilities, including hospitals, generate various types of medical waste, some of which can pose significant health and environmental risks if not managed properly [ 1 ]. Isolation waste, in particular, is a category of medical waste that requires special attention due to its potential to carry infectious agents [ 2 ]. These waste materials are generated from patients with contagious diseases or conditions, such as COVID-19, tuberculosis, or other communicable illnesses [ 3 ].…”

“…Proper management of isolation waste is crucial to prevent the transmission of infections among healthcare workers, patients, visitors, and waste handlers themselves [ 4 ]. Inadequate waste management practices can lead to the spread of infections both within the healthcare facility and in the broader community [ 2 ]. Particularly, improper disposal of isolation waste presents significant risks to both healthcare workers and the environment.…”

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.

Introduction: About 56% of total population of Nepal have been fully immunized against COVID. But still foreign nationals and Informal Waste Workers (IWWs) outside of Nepal are struggling to get COVID vaccines. This study was intended to study the COVID-19 symptoms among IWWs of Kathmandu and the usage of vaccines by them. Methods: A Cross-sectional study was conducted among 107 IWWs of Kathmandu Valley from Balku, Sanepa, Kalimati and Teku areas. A convenience sampling method was used to find the respondents based on their willingness to participate in the study. Face-to-face interview was conducted using structured questionnaire to collect data from IWWs. Results: A total of 53.3% males and 46.7% females participated in this study. Despite of majority of waste workers facing COVID related symptoms, only 19.6% of waste workers had done COVID test. Around 77.6% of waste workers hadn’t still taken COVID vaccine with majority (93.9 %) of them belonging to India. Conclusion: The majority of IWWs of Kathmandu are afraid to take COVID vaccine. Despite of having COVID related symptoms, IWWs haven’t gone for COVID test. Though interested, the IWWs needs identity cards for vaccination which counts less number of waste workers being vaccinated.
