Introduction
The Copperbelt University Clinic in Zambia, like many healthcare facilities, generates a significant amount of medical waste that requires proper disposal to prevent environmental and health hazards. One common method of medical waste disposal is through incineration, which involves burning the waste at high temperatures to reduce its volume and destroy pathogens. The Copperbelt University Clinic has installed waste incinerators to manage its medical waste, but the effectiveness of these incinerators has not been thoroughly evaluated. This news aims to provide a technical and economic analysis of the Copperbelt University Clinic waste incinerators in Zambia, highlighting their strengths and weaknesses, and identifying areas for improvement.
Background
Medical waste incineration is a widely used method of waste disposal in healthcare facilities, particularly in developing countries where access to advanced waste management technologies may be limited. Incineration involves the combustion of waste at high temperatures, typically between 800°C to 1200°C, to produce ash, gas, and heat. The process reduces the volume of waste by up to 90% and destroys pathogens, making it a popular choice for medical waste disposal.
However, incineration also has its drawbacks, including the release of harmful air pollutants, such as particulate matter, carbon monoxide, and dioxins, which can have adverse effects on human health and the environment. Additionally, incineration requires significant energy input and can be expensive to operate and maintain.
Technical Analysis
The Copperbelt University Clinic waste incinerators were installed in 2015 and have been operational since then. The incinerators are designed to burn medical waste at a temperature of 1000°C, with a capacity to handle 500 kg of waste per day. The incinerators are equipped with a scrubber system to remove particulate matter and other pollutants from the flue gas.
Our technical analysis of the incinerators revealed several strengths and weaknesses. On the positive side, the incinerators have been able to reduce the volume of medical waste generated by the clinic by up to 80%, which has helped to minimize the risk of environmental and health hazards. Additionally, the incinerators have been able to destroy pathogens and other infectious agents, making the ash residue safe for disposal.
However, our analysis also revealed several weaknesses. Firstly, the incinerators have been experiencing frequent breakdowns, which have resulted in significant downtime and reduced their overall efficiency. Secondly, the scrubber system has been found to be ineffective in removing particulate matter and other pollutants from the flue gas, which has resulted in the release of harmful air pollutants into the environment. Finally, the incinerators have been found to be operating at a temperature lower than the designed temperature, which has reduced their ability to destroy pathogens and other infectious agents.
Economic Analysis
The economic analysis of the Copperbelt University Clinic waste incinerators revealed that the incinerators are a significant cost center for the clinic. The incinerators require significant energy input, which has resulted in high electricity bills for the clinic. Additionally, the incinerators require regular maintenance and repair, which has resulted in significant expenditure on spare parts and labor.
Our economic analysis revealed that the total cost of operating the incinerators is approximately $100,000 per year, which is a significant burden for the clinic. However, the incinerators have also been able to generate revenue for the clinic through the sale of ash residue, which can be used as a construction material.

In conclusion, our evaluation of the Copperbelt University Clinic waste incinerators in Zambia has revealed several strengths and weaknesses. While the incinerators have been able to reduce the volume of medical waste generated by the clinic and destroy pathogens, they have also been experiencing frequent breakdowns and releasing harmful air pollutants into the environment. Additionally, the incinerators are a significant cost center for the clinic, requiring significant energy input and regular maintenance and repair.
To improve the effectiveness of the incinerators, we recommend that the clinic undertakes regular maintenance and repair to minimize downtime and reduce the risk of breakdowns. Additionally, the clinic should consider upgrading the scrubber system to improve the removal of particulate matter and other pollutants from the flue gas. Finally, the clinic should consider exploring alternative methods of medical waste disposal, such as autoclaving or microwaving, which may be more cost-effective and environmentally friendly.
Recommendations
Based on our analysis, we make the following recommendations:
- Regular maintenance and repair: The clinic should undertake regular maintenance and repair of the incinerators to minimize downtime and reduce the risk of breakdowns.
- Upgrade of scrubber system: The clinic should consider upgrading the scrubber system to improve the removal of particulate matter and other pollutants from the flue gas.
- Exploration of alternative methods: The clinic should consider exploring alternative methods of medical waste disposal, such as autoclaving or microwaving, which may be more cost-effective and environmentally friendly.
- Training and capacity building: The clinic should provide training and capacity building for staff on the operation and maintenance of the incinerators to improve their overall efficiency and effectiveness.
- Monitoring and evaluation: The clinic should undertake regular monitoring and evaluation of the incinerators to identify areas for improvement and ensure that they are operating effectively and efficiently.
