“…Maternities were also identified as major waste generator in Ribeiro et al ( 2020 ) study (Table 3 ). This may be attributed to maternities’ wards, since they are identified as major sources of infectious waste, although it be noted that the majority of HCW, in this location, can be classified as general waste with the implementation of proper segregation strategies (Abanyie et al 2021 ; Sawyerr et al 2017 ; Nemathaga et al 2008 ; Alani et al 2019 ).…”

Healthcare waste (HCW) management is a challenge for establishments that generate this type of waste, especially hospitals, as they are one of the largest generators. A determining factor in waste management is the amount of waste generation, which must be used for management planning. This study aims to compile and evaluate information on the management of HCW generated in Belo Horizonte’s (located in Brazil) hospitals declared in their respective Healthcare Waste Management Plans (HCWMP) sent for approval by the municipality’s Superintendency of Urban Cleaning. Therefore, a comparative analysis of the hospitals’ generations in relation to their characteristics (nature, specialty, and size) was carried out, using the Kruskal–Wallis statistical test with post hoc in Nemenyi. For the study hospitals, a generation rate of 7.18 (6.17–8.23) kg·bed −1 ·day −1 was estimated, a generation rate close to that of developed countries. When comparing the generation according to the specialty of the hospitals, it was identified that the maternity hospitals (9.00 (7.05–10.90)) kg·bed −1 ·day −1 had a significantly higher generation rate than the low-complexity hospitals (4.75 (3.28–6.18)) kg·bed −1 ·day −1 . It was also possible to demonstrate that the specialty and size of hospitals influence the structure available for waste storage. Finally, it can be observed that there are few treatment alternatives, with incineration and autoclaving being the technologies most commonly used by hospitals. It is expected that the results presented can serve as a reference for waste managers, in a context where there is little shared information on the subject.

Background.Scavengers, due to the nature of their work, are at risk of various occupational hazards while sorting for materials for recycling and sale. They are exposed to blood borne infections such as hepatitis B virus (HBV) infection from injuries from sharps and contact with discarded materials due to non-compliance with standard precautions.Objective.The present study assessed the prevalence of HBV and compliance with safety precautions among scavengers in Ilorin Metropolis, Kwara State, Nigeria.Methods.A cross-sectional study was conducted among 236 scavengers (comprised of scavengers dealing with biomedical wastes and those that were not) using structured questionnaires during the first stage of the study and a second testing stage. Data were analyzed using the Statistical Package for the Social Sciences (SPSS) software version 20.0 for descriptive and inferential statistics at a 5% level of significance.Results.The prevalence of HBV infection among the scavengers was found to be 17.4%, indicating that scavengers are at high risk of HBV infection. There was a significant difference in the prevalence of HBV among scavengers that handled biomedical wastes and those that did not. The majority of the scavengers (74.2%) did not have knowledge of or use standard precautions such as personal protective equipment (PPE). The level of injuries was considerably high and the treatment of injuries among scavengers illustrated their lack of awareness of the hazards involved in their occupations, as the majority of respondents (51.3%) engaged in self-treatment of occupational injuries.Conclusions.The probable pathway for virus transmission was waste handling, especially biomedical waste, which is mostly handled with bare hands without standard safety precautions. Vaccination against HBV, proper personal hygiene practices, regular training in occupational safety, monitoring by regulatory agencies and inclusion of scavengers in a mandatory health insurance scheme are recommended to control the risk of HBV infection among scavengers.Informed Consent. ObtainedEthical Approval:This study was approved by the Kwara State Ministry of Health Ethical Review Committee. Permission was also granted by the scrap dealers association through the Kwara State Environmental Protection Agency that oversees issues relating to the environment and public health in the state.Competing Interests.The authors declare no competing financial interests.

Healthcare waste management has become an important aspect of medical care delivery globally. This is simply because of its hazardous and infectious components that have greater potential for adverse health and environmental impacts. As such, certain guidelines and procedures have been developed by international aid agencies and conventions to guide national governments and local administrations in formulating policies and practices for effective healthcare waste management. In this work, we reviewed the existing literature to appraise the status of healthcare waste management practices in Nigeria. This included generation, segregation, collection, storage, transportation, treatment, and disposal. The current work further reviewed the other essential elements of healthcare waste management, such as policy landscapes, training, awareness, and waste characterization, and discusses challenges and opportunities for effective healthcare waste management in Nigeria. Among the challenges are poor funding, inadequate training, ineffective legislature, and absence of data. However, there are available low-cost technologies that are suitable for the treatment of waste in a developing country like Nigeria. This technology variant offers an opportunity for a circular economy as it can simultaneously achieve energy production, waste management, and other socioeconomic advantages.
