Evaluating the Effectiveness of Incinerators in Managing Medical Waste at Chikankata Mission Hospital, Zambia: A Study
Introduction
Medical waste management is a critical aspect of healthcare that requires attention to prevent environmental pollution and minimize health risks. In Zambia, the management of medical waste has become a pressing issue, particularly in hospitals where large amounts of waste are generated daily. Chikankata Mission Hospital, a major healthcare facility in the Southern Province of Zambia, has been using incinerators to manage its medical waste. This study aims to evaluate the effectiveness of incinerators in managing medical waste at Chikankata Mission Hospital.
Background
Medical waste includes all types of waste generated from healthcare facilities, such as hospitals, clinics, and laboratories. This waste can be categorized into different types, including infectious waste, non-infectious waste, sharps waste, and pharmaceutical waste. Improper management of medical waste can pose significant health risks to healthcare workers, patients, and the community at large. In Zambia, the management of medical waste is regulated by the Ministry of Health, which provides guidelines for the segregation, storage, transportation, and disposal of medical waste.
Incineration is one of the common methods used to manage medical waste. Incinerators are designed to burn waste at high temperatures, reducing the volume of waste and minimizing the risk of infection. However, the effectiveness of incinerators in managing medical waste depends on various factors, including the type of waste being incinerated, the design and maintenance of the incinerator, and the operating conditions.
Methodology
This study was conducted at Chikankata Mission Hospital, which is located in the Southern Province of Zambia. The hospital generates approximately 100 kg of medical waste per day, which is incinerated using a locally manufactured incinerator. The study involved a review of existing literature on medical waste management and incineration, as well as a field survey to collect data on the effectiveness of the incinerator at Chikankata Mission Hospital.
Data collection involved observing the incineration process, interviewing healthcare workers and waste management staff, and reviewing hospital records on waste generation and disposal. The study also involved analyzing samples of ash and emissions from the incinerator to determine the levels of pollutants and toxic substances.
Results
The study found that the incinerator at Chikankata Mission Hospital was effective in reducing the volume of medical waste generated by the hospital. The incinerator was able to burn approximately 90% of the waste generated by the hospital, leaving behind a small amount of ash and residue. However, the study also found that the incinerator was not properly maintained, which resulted in frequent breakdowns and the release of toxic emissions into the environment.
The analysis of ash and emissions samples revealed high levels of pollutants and toxic substances, including particulate matter, carbon monoxide, and dioxins. These substances can have serious health and environmental impacts, including respiratory problems, cancer, and environmental pollution.
The study also found that healthcare workers and waste management staff at the hospital were not adequately trained on the proper use and maintenance of the incinerator. This lack of training and awareness resulted in poor operating conditions, including inadequate temperature control and insufficient ash handling.
Discussion
The study demonstrated that while incineration can be an effective method for managing medical waste, it requires proper design, maintenance, and operation to minimize health and environmental risks. The findings of this study highlight the need for regular maintenance and training of healthcare workers and waste management staff to ensure that incinerators are operated safely and efficiently.
The study also highlights the importance of enforcing regulations and guidelines for medical waste management in Zambia. The Ministry of Health should provide clear guidelines and standards for the design, construction, and operation of incinerators, as well as training and capacity-building programs for healthcare workers and waste management staff.

In conclusion, the study found that the incinerator at Chikankata Mission Hospital was effective in reducing the volume of medical waste generated by the hospital. However, the study also found that the incinerator was not properly maintained, resulting in frequent breakdowns and the release of toxic emissions into the environment. The study recommends regular maintenance and training of healthcare workers and waste management staff, as well as enforcing regulations and guidelines for medical waste management in Zambia.
Recommendations
Based on the findings of this study, the following recommendations are made:
- Regular maintenance: The incinerator at Chikankata Mission Hospital should be regularly maintained to prevent breakdowns and ensure safe and efficient operation.
- Training and capacity-building: Healthcare workers and waste management staff should receive regular training and capacity-building programs to ensure that they are aware of the proper use and maintenance of the incinerator.
- Enforcement of regulations: The Ministry of Health should enforce regulations and guidelines for medical waste management in Zambia, including standards for the design, construction, and operation of incinerators.
- Alternative methods: The hospital should consider alternative methods for managing medical waste, such as autoclaving and recycling, to reduce the reliance on incineration.
- Community awareness: The hospital should raise awareness among the community on the importance of proper medical waste management and the risks associated with improper disposal.
