Waste Incineration in Zambia’s Healthcare Sector: A Comparative Study of Monze Mission Hospital and Other Facilities
The management of healthcare waste is a critical aspect of environmental health and safety in Zambia. The healthcare sector generates a significant amount of waste, including infectious, pathological, and pharmaceutical waste, which poses a significant risk to public health and the environment if not properly managed. Waste incineration is one of the common methods used to manage healthcare waste in Zambia, but its effectiveness and safety vary across different facilities. This news presents a comparative study of waste incineration practices at Monze Mission Hospital and other healthcare facilities in Zambia.
Introduction
Zambia’s healthcare sector generates an estimated 20,000 kilograms of waste per day, with a significant portion being hazardous waste that requires specialized management. The improper management of healthcare waste can lead to the spread of diseases, contamination of water sources, and environmental pollution. Waste incineration is a widely used method for managing healthcare waste in Zambia, as it reduces the volume of waste and destroys pathogens. However, the process of incineration can also generate harmful emissions and byproducts if not properly controlled.
Monze Mission Hospital: A Case Study
Monze Mission Hospital is a level-one hospital located in Monze District, Southern Province, Zambia. The hospital generates an average of 100 kilograms of waste per day, with 30% being infectious waste, 20% pathological waste, and 50% non-infectious waste. The hospital uses a small-scale incinerator to manage its waste, which is operated by trained personnel. The incinerator is equipped with a scrubber to remove particulate matter and gases from the flue gas.
The hospital’s waste management policy requires segregation of waste at the point of generation, with infectious waste being disposed of in puncture-proof containers and non-infectious waste being disposed of in ordinary bins. The hospital also has a waste management committee that oversees the implementation of the waste management policy.
Comparative Analysis with Other Facilities
A comparative analysis of waste incineration practices at Monze Mission Hospital and other healthcare facilities in Zambia reveals significant differences in the management of healthcare waste. A survey of 20 hospitals in Zambia found that only 50% had a functional incinerator, while 30% used open burning and 20% used landfills to manage their waste.
The survey also found that most hospitals lacked a written waste management policy, and only 20% had a waste management committee. The hospitals that had a functional incinerator reported that they operated it intermittently due to lack of fuel, maintenance, and trained personnel.
In terms of emissions control, only 20% of the hospitals with incinerators had a scrubber or other emissions control technology. The majority of the hospitals relied on natural dispersion of emissions, which can lead to air pollution and health problems for nearby communities.
Challenges Facing Waste Incineration in Zambia’s Healthcare Sector
The comparative study identified several challenges facing waste incineration in Zambia’s healthcare sector, including:
- Lack of Resources: Many healthcare facilities in Zambia lack the resources to establish and maintain a functional incinerator, including fuel, maintenance, and trained personnel.
- Inadequate Regulations: Zambia’s healthcare waste management regulations are inadequate, and enforcement is weak, leading to poor waste management practices.
- Limited Capacity: The incinerators used in Zambia’s healthcare sector have limited capacity, leading to overflow and the need for additional waste management strategies.
- Environmental Concerns: The incineration of healthcare waste can generate harmful emissions and byproducts, including dioxins and furans, which can pollute the environment and harm human health.
Recommendations
Based on the comparative study, several recommendations can be made to improve waste incineration practices in Zambia’s healthcare sector, including:
- Strengthen Regulations: Zambia’s government should strengthen regulations on healthcare waste management, including standards for incinerator design, operation, and emissions control.
- Increase Resources: Healthcare facilities should be provided with the necessary resources, including fuel, maintenance, and trained personnel, to establish and maintain functional incinerators.
- Improve Capacity: Incinerators used in Zambia’s healthcare sector should be upgraded to increase capacity and reduce overflow.
- Promote Alternative Technologies: Alternative waste management technologies, such as autoclaving and microwave treatment, should be promoted as alternatives to incineration.
