Reviewing the Sustainability of Waste Incineration at UNZA Clinic, Zambia: An Environmental Perspective
The University of Zambia (UNZA) Clinic, located in the heart of Lusaka, Zambia, is a major healthcare facility that provides medical services to the university community, as well as the general public. Like any other healthcare facility, the UNZA Clinic generates a significant amount of waste, including hazardous waste, which poses environmental and health risks if not managed properly. Waste incineration has been the primary method of waste disposal at the clinic, but its sustainability and environmental implications have raised concerns. This news reviews the sustainability of waste incineration at UNZA Clinic from an environmental perspective.
Introduction to Waste Incineration at UNZA Clinic
Waste incineration at UNZA Clinic involves the combustion of waste materials at high temperatures, typically between 800°C to 1300°C, to reduce the volume of waste and destroy pathogens. The clinic uses a small-scale incinerator, which is designed to handle the daily waste generated by the facility. The incinerator is operated by trained personnel, and the ash residue is disposed of in a designated landfill.
Environmental Concerns Associated with Waste Incineration
While waste incineration may seem like an efficient method of waste disposal, it has several environmental concerns. The combustion process releases pollutants, such as particulate matter, carbon monoxide, volatile organic compounds (VOCs), and heavy metals, into the atmosphere. These pollutants can have adverse effects on human health and the environment. For example, particulate matter can cause respiratory problems, while VOCs and heavy metals can contaminate soil and water.
Air Pollution
The incineration process at UNZA Clinic releases a significant amount of air pollutants, including particulate matter, carbon monoxide, and VOCs. These pollutants can contribute to poor air quality, which is a major environmental concern in urban areas like Lusaka. The World Health Organization (WHO) recommends that particulate matter (PM2.5) concentrations should not exceed 10 μg/m³, but the levels in Lusaka are often higher than this threshold. The incinerator at UNZA Clinic may be contributing to this problem, posing health risks to the surrounding community.
Water Pollution
The ash residue from the incinerator is disposed of in a landfill, but there is a risk of leachate Contamination of groundwater. Leachate is a toxic liquid that forms when rainwater passes through the ash residue, carrying heavy metals and other pollutants into the soil and groundwater. This can contaminate the water supply, posing health risks to the community. Furthermore, the incinerator’s scrubber system, which is used to remove pollutants from the flue gas, generates wastewater that requires proper treatment and disposal.
Soil Pollution
The ash residue from the incinerator can also contaminate soil, posing environmental and health risks. Heavy metals, such as lead and mercury, can persist in the soil for long periods, potentially entering the food chain and affecting human health. The ash residue may also be used as a construction material or disposed of in a landfill, but improper disposal can lead to soil pollution.
Sustainability of Waste Incineration at UNZA Clinic
The sustainability of waste incineration at UNZA Clinic is questionable, given the environmental concerns associated with the process. The clinic’s incinerator is a small-scale facility, but it still generates significant amounts of air pollutants and ash residue. The clinic’s waste management strategy should prioritize environmentally friendly methods, such as recycling, composting, and proper disposal of hazardous waste.
Alternative Waste Management Options
There are alternative waste management options that UNZA Clinic can consider to reduce its environmental footprint. These include:
- Recycling: Implementing a recycling program for paper, plastic, and glass waste can significantly reduce the amount of waste sent to the incinerator.
- Composting: Composting organic waste, such as food waste and yard trimmings, can reduce the amount of waste sent to the landfill and produce a valuable nutrient-rich soil amendment.
- Proper Disposal of Hazardous Waste: Improper disposal of hazardous waste, such as chemicals and pharmaceuticals, can contaminate soil and water. UNZA Clinic should ensure that hazardous waste is disposed of in accordance with national regulations and guidelines.
- Waste Reduction: Implementing waste reduction strategies, such as reducing paper use and encouraging staff and patients to reduce their waste, can minimize the amount of waste generated.

The sustainability of waste incineration at UNZA Clinic is a concern, given the environmental implications of the process. The clinic’s incinerator generates significant amounts of air pollutants and ash residue, posing health and environmental risks. Alternative waste management options, such as recycling, composting, and proper disposal of hazardous waste, should be considered to reduce the clinic’s environmental footprint. The clinic should prioritize environmentally friendly methods and ensure that waste management practices are aligned with national regulations and guidelines.
Recommendations
Based on this review, the following recommendations are made:
- Conduct an Environmental Impact Assessment: UNZA Clinic should conduct an environmental impact assessment to determine the extent of pollution caused by the incinerator and identify areas for improvement.
- Implement Alternative Waste Management Options: The clinic should implement alternative waste management options, such as recycling, composting, and proper disposal of hazardous waste, to reduce its environmental footprint.
- Upgrade the Incinerator: If the incinerator is to remain in operation, it should be upgraded to meet international standards and reduce emissions.
- Develop a Waste Management Policy: UNZA Clinic should develop a waste management policy that prioritizes environmentally friendly methods and ensures compliance with national regulations and guidelines.
