1.1 Background to the Study

Effective management of healthcare waste is a critical component of public health systems, particularly in low-resource settings where inadequate disposal practices pose significant risks to communities and ecosystems. Medical waste, including infectious materials, sharps, and chemical byproducts, requires systematic handling to mitigate environmental contamination and disease transmission (World Health Organization [WHO], 2020). In Nigeria, primary health centers (PHCs), serve as frontline healthcare providers, especially in rural and semi-urban areas like Obingwa Local Government Area (LGA). However, many PHCs in Nigeria struggle with insufficient infrastructure and limited adherence to standardized waste disposal protocols (Federal Ministry of Health [FMOH], 2021). For instance, improper incineration, open dumping, and lack of segregation are common, exacerbating risks of needle-stick injuries, air pollution, and groundwater contamination (Nwachukwu et al., 2021).

In Obingwa LGA, PHCs are pivotal in delivering maternal, child health, and immunization services, yet their waste management practices remain understudied. A 2022 survey of Nigerian PHCs revealed that only 35% complied with national guidelines for medical waste disposal, highlighting systemic gaps in training, funding, and regulatory enforcement (Okafor & Eze, 2022). These challenges are compounded in Obingwa, where rapid population growth and limited waste management infrastructure strain existing systems. Proper healthcare waste disposal is not only a regulatory obligation but also a moral imperative to safeguard community health. For example, improperly treated infectious waste can propagate pathogens like hepatitis B and HIV, disproportionately affecting vulnerable populations (Abdullahi et al., 2023). Furthermore, environmental degradation from toxic waste undermines agricultural livelihoods, which are central to Obingwa’s economy (Emenike et al., 2023). Addressing these issues requires context-specific strategies aligned with global best practices, emphasizing the urgency of evaluating and reforming waste disposal methods in Obingwa’s PHCs.

The global burden of healthcare waste has escalated in recent years, particularly with the surge in medical waste generated during the COVID-19 pandemic. According to the World Health Organization (WHO, 2021), healthcare facilities in low- and middle-income countries (LMICs), produce approximately 0.5 kg of hazardous waste per hospital bed daily, with a significant portion mismanaged due to inadequate infrastructure and poor regulatory oversight. In Nigeria, the situation is particularly dire, as many PHCs lack access to basic waste management tools such as incinerators, personal protective equipment (PPE), and color-coded waste bins (Adeyemi et al., 2022). This deficiency not only endangers healthcare workers but also exposes the broader community to preventable health risks. For instance, a study by Okeke et al. (2023), found that 60% of healthcare-associated infections in Nigerian PHCs were linked to improper waste disposal practices, underscoring the need for urgent intervention. Obingwa LGA, located in Abia State, Nigeria, is a microcosm of these challenges. With a population of over 300,000 residents, the LGA relies heavily on its network of PHCs to provide essential healthcare services. However, many of these facilities operate with limited resources, making it difficult to implement effective waste management systems. A 2023 assessment by Nwankwo et al. revealed that only 20% of PHCs in Obingwa had functional incinerators, while the majority relied on open burning or pit burial methods, which are neither safe nor sustainable. These practices release toxic pollutants into the air and soil, posing long-term environmental and public health risks (Eze et al., 2023).

 Furthermore, the lack of training among healthcare workers on proper waste segregation and disposal exacerbates the problem, as many are unaware of the potential hazards associated with mishandling medical waste (Uche et al., 2022). The importance of proper healthcare waste disposal cannot be overstated. Beyond preventing disease transmission, effective waste management contributes to environmental sustainability and aligns with the United Nations Sustainable Development Goals (SDGs), particularly Goal 3 (Good Health and Well-being), and Goal 6 (Clean Water and Sanitation), (United Nations, 2020). In Obingwa LGA, improving waste disposal practices in PHCs could significantly reduce the incidence of healthcare-associated infections, protect the environment, and enhance the overall quality of care. Moreover, it would serve as a model for other LGAs facing similar challenges, demonstrating the feasibility of implementing cost-effective and sustainable waste management solutions in resource-limited settings.

1.2 Statement of Problem

The improper disposal of healthcare waste in primary health centers (PHCs), poses a significant public health and environmental challenge, particularly in low-resource settings like Obingwa Local Government Area (LGA). Despite the existence of national and international guidelines for healthcare waste management, many PHCs in Nigeria, including those in Obingwa, continue to employ unsafe disposal methods such as open burning, pit burial, and indiscriminate dumping (Federal Ministry of Health [FMOH], 2021). These practices not only violate regulatory standards but also expose healthcare workers, patients, and the broader community to preventable health risks. For instance, a study by Nwachukwu et al. (2021), found that improper disposal of sharps and infectious waste in Nigerian PHCs contributed to a 40% increase in needle-stick injuries among healthcare workers, heightening the risk of bloodborne infections such as HIV and hepatitis B. In Obingwa LGA, the problem is exacerbated by inadequate infrastructure, limited funding, and a lack of training among healthcare workers. A 2023 assessment by Nwankwo et al. revealed that only 20% of PHCs in the LGA had functional incinerators, while the majority relied on outdated and hazardous methods like open burning. This not only releases toxic pollutants into the environment but also undermines efforts to achieve sustainable development goals related to health and environmental protection (United Nations, 2020). Furthermore, the absence of proper waste segregation practices in many PHCs increases the volume of hazardous waste, making disposal more complex and costly (Okafor & Eze, 2022).

The consequences of these poor waste management practices are far-reaching. Improperly disposed medical waste can contaminate water sources, soil, and air, leading to long-term environmental degradation and public health crises. For example, Emenike et al. (2023), documented cases of groundwater contamination in agrarian communities near PHCs in southeastern Nigeria, where leachate from medical waste had seeped into drinking water sources. Additionally, the lack of awareness and training among healthcare workers on proper waste disposal protocols further compounds the problem, as many are unaware of the risks associated with mishandling medical waste (Uche et al., 2022). Addressing these challenges requires a comprehensive understanding of the current waste disposal methods employed by PHCs in Obingwa LGA, as well as the barriers to implementing safer and more sustainable practices. Without urgent intervention, the continued mismanagement of healthcare waste will perpetuate environmental pollution, increase the burden of preventable diseases, and hinder progress toward achieving universal health coverage in the region. This study seeks to fill this gap by assessing the waste disposal methods practiced by PHCs in Obingwa LGA, identifying the underlying challenges, and proposing evidence-based solutions to improve waste management practices.
