Assessing the Efficiency of Mbeya Referral Hospital’s Waste Incinerator: A Study on Air Quality and Safety
Introduction
The proper management of medical waste is a critical aspect of healthcare, as it poses significant risks to human health and the environment if not handled correctly. In recent years, the use of incineration as a method of medical waste disposal has become increasingly popular, particularly in developing countries where access to advanced waste management infrastructure is limited. Mbeya Referral Hospital, located in the Mbeya Region of Tanzania, is one such facility that relies on incineration to manage its medical waste. However, concerns have been raised regarding the efficiency and safety of the hospital’s waste incinerator, prompting the need for a comprehensive assessment.
Background
Mbeya Referral Hospital is a 450-bed facility that provides tertiary healthcare services to a population of over 2 million people. The hospital generates approximately 500 kg of medical waste per day, including infectious waste, sharps, and pharmaceutical waste. To manage this waste, the hospital uses a small-scale incinerator that operates on a daily basis. However, there have been reports of poor air quality and safety concerns in the surrounding area, highlighting the need for an evaluation of the incinerator’s efficiency.
Methodology
This study employed a mixed-methods approach, combining both qualitative and quantitative data collection and analysis methods. The research team conducted a series of site visits to the hospital, during which they observed the incineration process, interviewed hospital staff, and collected air quality samples. The air quality samples were analyzed for particulate matter (PM2.5 and PM10), carbon monoxide (CO), and volatile organic compounds (VOCs). Additionally, the research team reviewed hospital records and conducted a survey of nearby residents to gather information on perceived air quality and safety concerns.
Results
The results of the study indicate that the incinerator at Mbeya Referral Hospital is not operating at optimal efficiency. The air quality samples revealed high levels of PM2.5 and PM10, exceeding the World Health Organization’s (WHO) recommended limits. The CO levels were also found to be higher than the acceptable standards, posing a significant risk to human health. Furthermore, the VOC analysis revealed the presence of toxic compounds, including dioxins and furans, which are known to have harmful effects on human health and the environment.
The survey of nearby residents revealed that 80% of respondents reported experiencing respiratory problems, including coughing, sneezing, and shortness of breath, which they attributed to the incinerator’s operations. The hospital staff also reported concerns regarding the incinerator’s safety, citing inadequate training and lack of personal protective equipment (PPE) as major issues.
Discussion
The findings of this study highlight the need for immediate attention to the incinerator’s efficiency and safety at Mbeya Referral Hospital. The high levels of air pollutants and toxic compounds released by the incinerator pose significant risks to human health and the environment. The lack of adequate training and PPE for hospital staff also raises concerns regarding their safety and well-being.
To address these issues, the hospital should consider implementing alternative waste management strategies, such as autoclaving or Microwaving, which are proven to be safer and more efficient. Additionally, the hospital should prioritize staff training and provide adequate PPE to ensure their safety while operating the incinerator.

The assessment of the waste incinerator at Mbeya Referral Hospital reveals significant concerns regarding air quality and safety. The high levels of air pollutants and toxic compounds released by the incinerator pose risks to human health and the environment. To mitigate these risks, the hospital should consider alternative waste management strategies and prioritize staff training and safety. Furthermore, the Tanzanian government should develop and implement policies to regulate medical waste management and ensure that healthcare facilities adhere to international standards for air quality and safety.
Recommendations
- Alternative waste management strategies: The hospital should consider implementing alternative waste management strategies, such as autoclaving or Microwaving, which are proven to be safer and more efficient.
- Staff training and PPE: The hospital should prioritize staff training and provide adequate PPE to ensure their safety while operating the incinerator.
- Regular maintenance: The hospital should ensure that the incinerator is regularly maintained and serviced to prevent malfunctions and minimize emissions.
- Air quality monitoring: The hospital should establish an air quality monitoring system to track emissions and ensure compliance with international standards.
- Policy development: The Tanzanian government should develop and implement policies to regulate medical waste management and ensure that healthcare facilities adhere to international standards for air quality and safety.
By implementing these recommendations, Mbeya Referral Hospital can improve the efficiency and safety of its waste incinerator, reducing the risks to human health and the environment. Additionally, the study’s findings can inform policy development and decision-making at the national level, contributing to the improvement of medical waste management practices in Tanzania.
