Waste Incineration at Chilenje Hospital: A Review of the Environmental and Health Impacts in Zambia
Waste incineration is a common practice in many healthcare facilities, including hospitals, in Zambia. Chilenje Hospital, a major healthcare facility in Lusaka, Zambia, has been using incineration as a method of waste disposal for many years. However, the environmental and health impacts of waste incineration at Chilenje Hospital have raised concerns among local communities, environmentalists, and health professionals. This news reviews the environmental and health impacts of waste incineration at Chilenje Hospital and discusses the potential risks and consequences of this practice.
Introduction to Waste Incineration
Waste incineration is the process of burning waste materials at high temperatures, typically between 800°C to 1300°C, to reduce the volume of waste and destroy pathogens and other hazardous materials. Incineration is often used in healthcare facilities to dispose of infectious waste, such as surgical waste, anatomical waste, and pharmaceutical waste. However, incineration can also release toxic pollutants, such as dioxins, furans, and particulate matter, into the atmosphere, posing environmental and health risks.
Environmental Impacts of Waste Incineration
The environmental impacts of waste incineration at Chilenje Hospital are a major concern. The incineration process releases toxic pollutants, such as dioxins and furans, into the atmosphere, which can have severe environmental and health consequences. Dioxins and furans are known to be carcinogenic and can cause a range of health problems, including cancer, reproductive and developmental problems, and immunological disorders.
The incineration process also releases particulate matter, including fine pnewss (PM2.5) and coarse pnewss (PM10), into the atmosphere. Particulate matter can cause respiratory problems, such as asthma and chronic obstructive pulmonary disease (COPD), and can also exacerbate existing cardiovascular and respiratory conditions.
Additionally, the incineration process can also release heavy metals, such as lead, mercury, and cadmium, into the atmosphere. Heavy metals can contaminate soil and water, posing environmental and health risks to local communities.
Health Impacts of Waste Incineration
The health impacts of waste incineration at Chilenje Hospital are also a major concern. Exposure to toxic pollutants, such as dioxins and furans, can cause a range of health problems, including cancer, reproductive and developmental problems, and immunological disorders. The World Health Organization (WHO) has classified dioxins as a known human carcinogen, and exposure to dioxins has been linked to an increased risk of cancer, particularly lung cancer and non-Hodgkin lymphoma.
Exposure to particulate matter, including fine pnewss (PM2.5) and coarse pnewss (PM10), can also cause respiratory problems, such as asthma and COPD, and can exacerbate existing cardiovascular and respiratory conditions. The WHO has estimated that exposure to particulate matter is responsible for approximately 800,000 premature deaths worldwide each year.
Case Study: Chilenje Hospital
Chilenje Hospital is a major healthcare facility in Lusaka, Zambia, and has been using incineration as a method of waste disposal for many years. The hospital’s incinerator is located in a densely populated area, and local communities have raised concerns about the environmental and health impacts of the incineration process.
A study conducted in 2020 found that the incinerator at Chilenje Hospital was releasing high levels of particulate matter, including fine pnewss (PM2.5) and coarse pnewss (PM10), into the atmosphere. The study also found that the incinerator was releasing high levels of dioxins and furans, which are known to be carcinogenic.
Alternatives to Waste Incineration
There are several alternatives to waste incineration that can be used to dispose of healthcare waste, including:
- Autoclaving: Autoclaving is a process that uses steam to sterilize waste, making it safe for disposal. Autoclaving is a cost-effective and environmentally friendly alternative to incineration.
- Microwaving: Microwaving is a process that uses microwave energy to sterilize waste, making it safe for disposal. Microwaving is a cost-effective and environmentally friendly alternative to incineration.
- Landfilling: Landfilling is a process that involves burying waste in a landfill. Landfilling is a cost-effective alternative to incineration, but it can have environmental and health impacts if not managed properly.
- Recycling: Recycling is a process that involves converting waste into new products. Recycling is a cost-effective and environmentally friendly alternative to incineration.

Waste incineration at Chilenje Hospital poses significant environmental and health risks to local communities. The incineration process releases toxic pollutants, such as dioxins and furans, into the atmosphere, which can cause a range of health problems, including cancer, reproductive and developmental problems, and immunological disorders. Alternative methods of waste disposal, such as autoclaving, microwaving, landfilling, and recycling, should be considered to reduce the environmental and health impacts of waste incineration.
Recommendations
Based on the findings of this review, the following recommendations are made:
- Conduct a comprehensive environmental and health impact assessment: A comprehensive environmental and health impact assessment should be conducted to determine the extent of the environmental and health impacts of waste incineration at Chilenje Hospital.
- Implement alternative methods of waste disposal: Alternative methods of waste disposal, such as autoclaving, microwaving, landfilling, and recycling, should be implemented to reduce the environmental and health impacts of waste incineration.
- Provide training and education: Training and education should be provided to healthcare workers on the safe handling and disposal of healthcare waste.
- Engage with local communities: Local communities should be engaged and informed about the environmental and health impacts of waste incineration and alternative methods of waste disposal.
