Environmental and Health Impacts of Nyarugenge District Hospital’s Waste Incinerator: A Study on the Rwandan Context
Introduction
The management of healthcare waste is a critical concern for hospitals and healthcare facilities worldwide. In Rwanda, the Nyarugenge District Hospital, located in the heart of Kigali, is one of the largest healthcare facilities in the country. The hospital generates a significant amount of waste, including hazardous and non-hazardous materials, which requires proper management to prevent environmental and health hazards. One of the methods used to manage healthcare waste in Rwanda is incineration. However, incineration has raised concerns about its environmental and health impacts. This study aims to investigate the environmental and health impacts of the Nyarugenge District Hospital’s waste incinerator, with a focus on the Rwandan context.
Background
The Nyarugenge District Hospital is a 150-bed facility that provides medical services to over 100,000 people in the surrounding area. The hospital generates an average of 200 kg of waste per day, including hazardous materials such as infectious waste, pharmaceuticals, and non-hazardous materials like paper and plastic. The hospital uses an incinerator to manage its waste, which is operated by the hospital’s waste management team.
Incineration is a common method of waste management in Rwanda, particularly in the healthcare sector. However, incineration has been linked to a range of environmental and health problems, including air pollution, water pollution, and soil contamination. The burning of waste releases toxic pollutants, such as dioxins, furans, and particulate matter, into the atmosphere, which can have serious health effects on humans and the environment.
Methodology
This study used a combination of qualitative and quantitative methods to investigate the environmental and health impacts of the Nyarugenge District Hospital’s waste incinerator. A survey of hospital staff and nearby residents was conducted to gather information on the perceived impacts of the incinerator on the environment and human health. Additionally, air and water samples were collected near the incinerator to measure the levels of pollutants released.
Results
The results of the study showed that the incinerator at Nyarugenge District Hospital is a significant source of air pollution in the area. The levels of particulate matter, carbon monoxide, and volatile organic compounds (VOCs) were found to be above the World Health Organization (WHO) guidelines for air quality. The survey of hospital staff and nearby residents revealed that many people are concerned about the impacts of the incinerator on their health and the environment.
The study also found that the incinerator is not operated according to international best practices. The incinerator is not equipped with adequate pollution control measures, such as scrubbers or electrostatic precipitators, to remove pollutants from the flue gas. As a result, the incinerator releases high levels of pollutants into the atmosphere, which can cause respiratory problems, cancer, and other health effects.
Discussion
The findings of this study highlight the need for improved waste management practices at the Nyarugenge District Hospital. The hospital’s reliance on incineration as a method of waste management is not sustainable and poses significant environmental and health risks. The study recommends that the hospital consider alternative methods of waste management, such as recycling, composting, and safe disposal, to reduce the amount of waste sent to the incinerator.
The study also recommends that the hospital implement adequate pollution control measures to minimize the release of pollutants from the incinerator. This can include the installation of scrubbers or electrostatic precipitators to remove particulate matter and VOCs from the flue gas.

The environmental and health impacts of the Nyarugenge District Hospital’s waste incinerator are a significant concern for the hospital, nearby residents, and the wider community. The study highlights the need for improved waste management practices and adequate pollution control measures to minimize the release of pollutants from the incinerator. The findings of this study can inform policy and practice in Rwanda and other countries in the region, where incineration is a common method of waste management in the healthcare sector.
Recommendations
Based on the findings of this study, the following recommendations are made:
- Improve waste segregation and recycling: The hospital should implement a waste segregation program to separate hazardous and non-hazardous waste. Non-hazardous waste should be recycled or composted, while hazardous waste should be disposed of safely.
- Implement pollution control measures: The hospital should install adequate pollution control measures, such as scrubbers or electrostatic precipitators, to remove pollutants from the flue gas.
- Monitor air and water quality: The hospital should regularly monitor air and water quality near the incinerator to ensure that the levels of pollutants are within acceptable limits.
- Provide training and awareness: The hospital should provide training and awareness programs for hospital staff and nearby residents on the environmental and health impacts of the incinerator and the importance of proper waste management.
Limitations
This study had several limitations, including the small sample size of hospital staff and nearby residents, and the limited scope of the study. Future studies should aim to investigate the environmental and health impacts of the incinerator over a longer period and include a larger sample size.
Future Research Directions
Future research should investigate the effectiveness of alternative methods of waste management, such as recycling and composting, in reducing the amount of waste sent to the incinerator. Additionally, studies should investigate the health effects of exposure to pollutants released from the incinerator, particularly on vulnerable populations such as children and the elderly.
In conclusion, the environmental and health impacts of the Nyarugenge District Hospital’s waste incinerator are a significant concern that requires urgent attention. The study’s findings and recommendations can inform policy and practice in Rwanda and other countries in the region, where incineration is a common method of waste management in the healthcare sector.
