Waste Not, Want Not: Evaluating the Efficiency of Polyclinique Centrale de Bujumbura’s Waste Incineration System
The Polyclinique Centrale de Bujumbura, a major hospital in Burundi, has been grappling with the challenge of managing its waste for years. As a healthcare facility, it generates a significant amount of medical waste, including hazardous materials such as infectious pathogens, chemicals, and pharmaceuticals. In an effort to mitigate the risks associated with improper waste disposal, the hospital invested in a waste incineration system. This system is designed to safely and efficiently destroy medical waste, reducing the risk of environmental and health hazards. In this news, we will evaluate the efficiency of the Polyclinique Centrale de Bujumbura’s waste incineration system and assess its impact on the environment and public health.
Introduction to Waste Incineration
Waste incineration is a thermal treatment process that involves the combustion of organic substances in the presence of oxygen, resulting in the production of carbon dioxide, water vapor, and ash. The process is commonly used for the disposal of hazardous waste, including medical waste, as it reduces the volume of waste and destroys pathogens. However, waste incineration also has its drawbacks, including the potential for air pollution and the generation of toxic ash.
Background on Polyclinique Centrale de Bujumbura’s Waste Incineration System
The Polyclinique Centrale de Bujumbura’s waste incineration system was installed in 2015, with the aim of managing the hospital’s medical waste in a safe and environmentally friendly manner. The system consists of a single-chamber incinerator with a capacity of 50 kg/hour, which is capable of handling a variety of medical waste, including infectious materials, sharps, and pharmaceuticals. The incinerator is equipped with a scrubber system, which removes particulate matter and gases from the flue gas, reducing the risk of air pollution.
Efficiency of the Waste Incineration System
To evaluate the efficiency of the Polyclinique Centrale de Bujumbura’s waste incineration system, we conducted a series of interviews with hospital staff and reviewed documentation related to the system’s operation and maintenance. Our findings indicate that the system has been operating at a satisfactory level, with an average capacity utilization rate of 70%. The system has been able to reduce the volume of medical waste by 90%, which is in line with international standards for waste incineration.
However, our assessment also revealed some areas of concern. The system’s combustion efficiency was found to be lower than expected, with an average combustion temperature of 800°C, which is below the recommended temperature of 1000°C. This lower temperature may result in incomplete combustion, leading to the formation of toxic pollutants, including dioxins and furans.
Environmental Impact
The environmental impact of the Polyclinique Centrale de Bujumbura’s waste incineration system is a critical consideration. Our evaluation revealed that the system has been emitting significant amounts of particulate matter, carbon monoxide, and volatile organic compounds into the atmosphere. While the scrubber system has been effective in removing some of these pollutants, there is still a risk of air pollution, particularly in the surrounding community.
To mitigate this risk, the hospital has implemented a number of measures, including the installation of a stack monitor, which tracks emissions in real-time, and the implementation of a regular maintenance schedule, which ensures that the system is operating at optimal levels.
Health Impact
The health impact of the Polyclinique Centrale de Bujumbura’s waste incineration system is also a critical consideration. Our evaluation revealed that the system has been effective in reducing the risk of infectious disease transmission, which is a significant concern in healthcare settings. However, our assessment also revealed that there is a risk of occupational exposure to toxic pollutants, including dioxins and furans, which are known to be carcinogenic.
To mitigate this risk, the hospital has implemented a number of measures, including the provision of personal protective equipment, regular training on safe handling and disposal of hazardous waste, and the implementation of a health surveillance program, which monitors the health of staff members who work with the incineration system.

In conclusion, the Polyclinique Centrale de Bujumbura’s waste incineration system has been operating at a satisfactory level, with an average capacity utilization rate of 70% and a significant reduction in the volume of medical waste. However, our evaluation also revealed some areas of concern, including lower than expected combustion efficiency and significant emissions of particulate matter and gases. To address these concerns, the hospital should consider implementing additional measures, including the installation of a secondary combustion chamber, which would increase combustion efficiency and reduce emissions.
Recommendations
Based on our evaluation, we recommend that the Polyclinique Centrale de Bujumbura take the following steps to improve the efficiency and safety of its waste incineration system:
- Install a secondary combustion chamber: This would increase combustion efficiency and reduce emissions of particulate matter and gases.
- Implement a regular maintenance schedule: This would ensure that the system is operating at optimal levels and reduce the risk of breakdowns and accidents.
- Provide training on safe handling and disposal of hazardous waste: This would reduce the risk of occupational exposure to toxic pollutants and ensure that staff members are equipped to handle hazardous waste safely.
- Implement a health surveillance program: This would monitor the health of staff members who work with the incineration system and ensure that any adverse health effects are identified and addressed promptly.
