Sustainable Waste Disposal through Incineration: The Case of Chisekesi Rural Health Centre in Zambia

The management of waste, particularly in healthcare settings, is a critical issue that requires attention to prevent environmental pollution and the spread of diseases. In developing countries like Zambia, the lack of proper waste disposal facilities and infrastructure poses significant challenges to healthcare providers. One of the effective methods of waste disposal is incineration, which involves the burning of waste materials at high temperatures to reduce their volume and destroy pathogens. This news explores the case of Chisekesi Rural Health Centre in Zambia, which has adopted incineration as a sustainable waste disposal method.

Introduction to Chisekesi Rural Health Centre

Chisekesi Rural Health Centre is a healthcare facility located in the Monze District of Southern Province, Zambia. The health centre provides primary healthcare services to the local community, including outpatient and inpatient services, maternity care, and laboratory testing. With a population of over 10,000 people in the surrounding area, the health centre generates a significant amount of waste, including medical waste, sharps, and non-medical waste.

The Need for Sustainable Waste Disposal

The improper disposal of waste at Chisekesi Rural Health Centre posed significant environmental and health risks to the community. The health centre’s waste was previously disposed of in a dumpsite near the facility, which was not only an eyesore but also a breeding ground for pests and a source of air pollution. The lack of proper waste disposal facilities also led to the burning of waste in open pits, which released toxic fumes into the atmosphere. The health centre recognized the need for a sustainable waste disposal method that would minimize environmental pollution and protect public health.

Incineration as a Sustainable Waste Disposal Method

Incineration is a waste disposal method that involves the burning of waste materials at high temperatures, typically between 800°C to 1300°C. The process reduces the volume of waste by up to 90% and destroys pathogens, making it an effective method for managing infectious waste. Incineration also produces energy in the form of heat, which can be used to generate electricity or provide hot water.

At Chisekesi Rural Health Centre, an incinerator was installed to manage the facility’s waste. The incinerator is a simple, locally manufactured unit that burns waste at a temperature of 1000°C. The incinerator is fueled by diesel, which is readily available in the area. The health centre’s waste is sorted and segregated into different categories, including medical waste, sharps, and non-medical waste, before being fed into the incinerator.

Benefits of Incineration at Chisekesi Rural Health Centre

The adoption of incineration as a waste disposal method at Chisekesi Rural Health Centre has brought numerous benefits to the facility and the surrounding community. Some of the benefits include:

1. Reduced environmental pollution: The incinerator has significantly reduced the amount of waste disposed of in the dumpsite, minimizing the risk of environmental pollution and protecting public health.
2. Destruction of pathogens: The high temperatures achieved in the incinerator destroy pathogens, reducing the risk of disease transmission and protecting the community from infectious diseases.
3. Energy generation: The incinerator produces energy in the form of heat, which is used to generate hot water for the health centre’s laundry and kitchen facilities.
4. Improved waste management: The incinerator has improved waste management practices at the health centre, with waste being sorted and segregated before being fed into the incinerator.
5. Cost savings: The incinerator has reduced the health centre’s waste disposal costs, as the facility no longer needs to transport waste to the dumpsite or pay for waste disposal services.

Challenges and Limitations

While incineration has proven to be an effective waste disposal method at Chisekesi Rural Health Centre, there are several challenges and limitations that need to be addressed. Some of the challenges include:

1. Fuel costs: The incinerator is fueled by diesel, which can be expensive, particularly in rural areas where fuel distribution networks are limited.
2. Maintenance costs: The incinerator requires regular maintenance to ensure optimal performance, which can be costly, particularly for a rural health centre with limited resources.
3. Air pollution: Incineration can produce air pollutants, including particulate matter, carbon monoxide, and volatile organic compounds, which can have negative impacts on public health and the environment.
4. Community acceptance: Incineration can be a controversial waste disposal method, particularly in rural areas where communities may be concerned about the environmental and health impacts of the technology.

The adoption of incineration as a waste disposal method at Chisekesi Rural Health Centre in Zambia has proven to be an effective and sustainable solution for managing the facility’s waste. The incinerator has reduced environmental pollution, destroyed pathogens, and generated energy, while also improving waste management practices and reducing costs. However, there are several challenges and limitations that need to be addressed, including fuel costs, maintenance costs, air pollution, and community acceptance. With proper planning, management, and maintenance, incineration can be a valuable tool for healthcare facilities in developing countries, particularly in rural areas where waste disposal infrastructure is limited.
