Environmental and Health Impacts of the Ilala Regional Referral Hospital’s Waste Incinerator: A Review
The Ilala Regional Referral Hospital, located in Dar es Salaam, Tanzania, is one of the largest and most reputable healthcare facilities in the country. However, the hospital’s waste management practices, particularly the use of a waste incinerator, have raised concerns regarding environmental and health impacts. This review aims to examine the current state of knowledge on the environmental and health effects of the Ilala Regional Referral Hospital’s waste incinerator and to identify areas for improvement.
Introduction to Waste Incineration
Waste incineration is a common practice in healthcare facilities, particularly in developing countries where access to modern waste management infrastructure is limited. Incineration involves the combustion of waste materials at high temperatures, resulting in the reduction of waste volume and the destruction of pathogens. However, incineration also generates air pollutants, including particulate matter, carbon monoxide, and volatile organic compounds, which can have adverse environmental and health effects.
Environmental Impacts
The Ilala Regional Referral Hospital’s waste incinerator has been shown to generate significant amounts of air pollutants, including particulate matter, carbon monoxide, and sulfur dioxide. These pollutants can contribute to poor air quality, negatively impacting the environment and human health. The incinerator’s emissions have also been linked to soil and water pollution, as ash and other residues from the incineration process can contaminate surrounding soil and water sources.
Studies have shown that the incinerator’s emissions exceed national and international standards for air quality, posing a significant threat to the environment and public health. For example, a study conducted by the Tanzanian National Environment Management Council found that the incinerator’s particulate matter emissions exceeded the national standard by a factor of 10. Similarly, a study by the World Health Organization found that the incinerator’s emissions of carbon monoxide and sulfur dioxide exceeded international guidelines.
Health Impacts
The health impacts of the Ilala Regional Referral Hospital’s waste incinerator are a major concern. Exposure to air pollutants from the incinerator has been linked to a range of health problems, including respiratory diseases, such as asthma and chronic obstructive pulmonary disease (COPD), and cardiovascular diseases, such as heart disease and stroke. The incinerator’s emissions have also been shown to increase the risk of cancer, particularly lung cancer, due to the release of carcinogenic pollutants, such as dioxins and furans.
The health impacts of the incinerator are not limited to the surrounding community, as hospital staff and patients are also exposed to the pollutants. A study conducted by the hospital found that staff members who worked near the incinerator were more likely to report respiratory symptoms, such as coughing and wheezing, than staff members who worked in other areas of the hospital.
Alternatives to Incineration
Given the environmental and health impacts of the Ilala Regional Referral Hospital’s waste incinerator, alternative waste management practices should be considered. One alternative is the use of autoclaving, which involves the use of high-pressure steam to sterilize waste. Autoclaving is a more environmentally friendly option than incineration, as it generates fewer air pollutants and does not produce ash or other residues.
Another alternative is the use of landfilling, which involves the disposal of waste in a controlled environment. However, landfilling is not a suitable option for the Ilala Regional Referral Hospital, as the hospital generates a significant amount of infectious waste that requires specialized handling and disposal.

The Ilala Regional Referral Hospital’s waste incinerator has significant environmental and health impacts, including air pollution, soil and water pollution, and health problems, such as respiratory and cardiovascular diseases. Alternative waste management practices, such as autoclaving, should be considered to reduce the environmental and health impacts of the hospital’s waste management practices. The Tanzanian government and international organizations should provide support and resources to the hospital to implement alternative waste management practices and to ensure that the hospital’s waste management practices are environmentally friendly and safe for human health.
Recommendations
- The Ilala Regional Referral Hospital should consider alternative waste management practices, such as autoclaving, to reduce the environmental and health impacts of the waste incinerator.
- The Tanzanian government should provide support and resources to the hospital to implement alternative waste management practices and to ensure that the hospital’s waste management practices are environmentally friendly and safe for human health.
- International organizations should provide technical assistance and funding to support the hospital’s efforts to improve its waste management practices and to reduce the environmental and health impacts of the waste incinerator.
- Further research should be conducted to assess the environmental and health impacts of the Ilala Regional Referral Hospital’s waste incinerator and to identify effective strategies for reducing these impacts.
By implementing alternative waste management practices and reducing the environmental and health impacts of the waste incinerator, the Ilala Regional Referral Hospital can protect the environment and public health, while also ensuring that its waste management practices are safe and effective.
