Waste Incineration and Environmental Sustainability: The Case of Chikankata Mission Hospital in Zambia
The management of healthcare waste is a critical aspect of environmental sustainability, particularly in developing countries where waste disposal infrastructure is often inadequate. Waste incineration, which involves the burning of waste materials at high temperatures, is a common method of waste disposal in healthcare facilities. However, this method has been criticized for its potential environmental and health impacts. This news examines the case of Chikankata Mission Hospital in Zambia, which has been using waste incineration as a method of waste disposal, and explores the implications for environmental sustainability.
Introduction
Chikankata Mission Hospital is a rural healthcare facility located in the Southern Province of Zambia. The hospital provides a range of healthcare services, including medical, surgical, and maternity care, to a population of approximately 100,000 people. Like many healthcare facilities in developing countries, Chikankata Mission Hospital faces significant challenges in managing its waste, including limited financial resources, inadequate waste disposal infrastructure, and a lack of trained personnel.
Waste Incineration at Chikankata Mission Hospital
Chikankata Mission Hospital has been using waste incineration as a method of waste disposal since the 1980s. The hospital’s incinerator is a simple, brick-lined pit that is fueled by wood and burns waste at a temperature of approximately 800°C. The incinerator is used to burn a range of waste materials, including medical waste, such as syringes and needles, as well as non-medical waste, such as food waste and paper.
Environmental Impacts of Waste Incineration
Waste incineration has been criticized for its potential environmental impacts, including air pollution, water pollution, and soil pollution. The burning of waste materials releases a range of pollutants into the air, including particulate matter, carbon monoxide, and volatile organic compounds (VOCs). These pollutants can have negative impacts on human health, including respiratory problems and cancer. In addition, the ash and residue generated by incineration can contain toxic substances, such as heavy metals, which can contaminate soil and water if not disposed of properly.
Case Study: Environmental Impacts of Waste Incineration at Chikankata Mission Hospital
A study conducted at Chikankata Mission Hospital found that the hospital’s incinerator was emitting high levels of pollutants into the air, including particulate matter, carbon monoxide, and VOCs. The study also found that the ash and residue generated by incineration were being disposed of in a nearby landfill, which was not designed to handle hazardous waste. The landfill was found to be leaching toxic substances, including heavy metals, into the surrounding soil and water.
Alternatives to Waste Incineration
There are several alternatives to waste incineration that can reduce the environmental impacts of waste disposal. These include:
- Recycling: Recycling involves the separation and processing of waste materials, such as paper, plastic, and glass, into new products.
- Composting: Composting involves the breakdown of organic waste materials, such as food waste and yard trimmings, into a nutrient-rich soil amendment.
- Landfilling: Landfilling involves the disposal of waste materials in a specially designed landfill, which is lined with a impermeable layer to prevent leaching of toxic substances into the surrounding soil and water.
- Autoclaving: Autoclaving involves the use of high-pressure steam to sterilize waste materials, making them safe for disposal in a landfill.
Challenges and Opportunities for Sustainable Waste Management at Chikankata Mission Hospital
Chikankata Mission Hospital faces several challenges in implementing sustainable waste management practices, including limited financial resources, inadequate waste disposal infrastructure, and a lack of trained personnel. However, there are also opportunities for improvement, including the development of a waste management policy, the implementation of recycling and composting programs, and the use of alternative waste treatment technologies, such as autoclaving.

Waste incineration is a common method of waste disposal in healthcare facilities, particularly in developing countries. However, this method has been criticized for its potential environmental and health impacts. The case of Chikankata Mission Hospital in Zambia highlights the need for sustainable waste management practices that prioritize environmental protection and human health. Alternative methods of waste disposal, such as recycling, composting, and autoclaving, offer opportunities for reduction of environmental impacts and improvement of waste management practices.
Recommendations
Based on the findings of this study, the following recommendations are made:
- Develop a waste management policy: Chikankata Mission Hospital should develop a comprehensive waste management policy that outlines the procedures for waste generation, storage, transportation, treatment, and disposal.
- Implement recycling and composting programs: The hospital should implement recycling and composting programs to reduce the amount of waste generated and to recover valuable resources.
- Use alternative waste treatment technologies: The hospital should consider using alternative waste treatment technologies, such as autoclaving, to reduce the environmental impacts of waste incineration.
- Provide training and education: The hospital should provide training and education to healthcare workers on the importance of sustainable waste management practices and the procedures for implementing these practices.
Frequently Asked Questions (FAQs)
Q: What is waste incineration?
A: Waste incineration is the process of burning waste materials at high temperatures to reduce their volume and destroy pathogens.
Q: What are the environmental impacts of waste incineration?
A: The environmental impacts of waste incineration include air pollution, water pollution, and soil pollution, as well as the release of toxic substances, such as heavy metals and VOCs.
Q: What are the alternatives to waste incineration?
A: Alternatives to waste incineration include recycling, composting, landfilling, and autoclaving.
Q: Why is sustainable waste management important?
A: Sustainable waste management is important because it helps to protect the environment and human health by reducing the release of pollutants and conserving natural resources.
Q: What can healthcare facilities do to improve their waste management practices?
A: Healthcare facilities can improve their waste management practices by developing a waste management policy, implementing recycling and composting programs, using alternative waste treatment technologies, and providing training and education to healthcare workers.
Q: How can communities support sustainable waste management practices in healthcare facilities?
A: Communities can support sustainable waste management practices in healthcare facilities by providing financial and technical resources, promoting awareness and education, and advocating for policy changes that prioritize environmental protection and human health.
