Waste Incineration and Environmental Governance in Zambia: The Case of Livingstone General Hospital
Introduction
Waste management is a critical aspect of environmental governance in any country. The rapid growth of urban populations and the increasing generation of waste have put pressure on governments to develop effective waste management strategies. In Zambia, the management of waste, particularly in healthcare facilities, has been a challenge due to inadequate infrastructure, lack of resources, and limited enforcement of environmental regulations. This news examines the issue of waste incineration and environmental governance in Zambia, with a focus on Livingstone General Hospital.
Background
Zambia, like many other developing countries, faces significant challenges in managing its waste. The country’s population is growing rapidly, and this has resulted in an increase in waste generation. The healthcare sector is a significant contributor to waste generation, with hospitals producing large quantities of medical waste, including infectious and non-infectious waste. Livingstone General Hospital, located in the tourist town of Livingstone, is one of the largest hospitals in Zambia and generates a significant amount of medical waste.
Waste Incineration in Zambia
Waste incineration is a common method of waste disposal in Zambia, particularly in healthcare facilities. Incineration involves the burning of waste at high temperatures, reducing the volume of waste and killing pathogens. However, incineration has been criticized for its potential environmental and health impacts. The incineration process releases toxic pollutants, including dioxins, furans, and particulate matter, into the atmosphere, which can have serious health effects. Additionally, incineration does not address the root cause of waste generation and can create a culture of disposal rather than reduction and recycling.
Livingstone General Hospital’s Waste Management Practices
Livingstone General Hospital generates approximately 2-3 tons of medical waste per day. The hospital uses a combination of incineration and disposal methods to manage its waste. The hospital has an on-site incinerator, which burns a significant portion of the medical waste. However, the incinerator is old and poorly maintained, leading to frequent breakdowns and releases of toxic pollutants into the atmosphere. The hospital also disposes of some of its waste in a nearby landfill, which is not designed to handle medical waste.
Environmental Governance in Zambia
Zambia has a number of environmental laws and regulations that govern waste management, including the Environmental Management Act of 2011. The Act establishes the Environmental Management Authority, which is responsible for enforcing environmental regulations and ensuring compliance with environmental laws. However, the Authority has limited resources and capacity to enforce regulations, particularly in rural areas.
The Ministry of Health is responsible for developing and implementing policies and guidelines for waste management in healthcare facilities. The Ministry has developed a number of guidelines and protocols for waste management, including the use of personal protective equipment and the segregation of medical waste. However, these guidelines are not always followed, and there is a lack of monitoring and enforcement.
Challenges Facing Waste Incineration in Zambia
There are several challenges facing waste incineration in Zambia, including:
- Lack of infrastructure: Many healthcare facilities in Zambia lack adequate infrastructure for waste management, including incinerators, autoclaves, and landfills.
- Limited resources: The government and healthcare facilities have limited resources to invest in waste management, including funding, personnel, and equipment.
- Limited enforcement: There is limited enforcement of environmental regulations, particularly in rural areas, which can lead to non-compliance and environmental degradation.
- Lack of public awareness: There is a lack of public awareness about the importance of proper waste management and the potential health and environmental impacts of poor waste management practices.
Alternatives to Incineration
There are several alternatives to incineration that can be used to manage medical waste, including:
- Autoclaving: Autoclaving involves the use of high-pressure steam to sterilize medical waste. This method is effective and can be used to treat a wide range of medical waste.
- Microwaving: Microwaving involves the use of microwave energy to sterilize medical waste. This method is effective and can be used to treat a wide range of medical waste.
- Recycling: Recycling involves the separation and processing of recyclable materials, such as paper, plastic, and glass. This method can be used to reduce the amount of waste generated and conserve natural resources.
- Landfilling: Landfilling involves the disposal of waste in a landfill. This method should only be used as a last resort, as it can lead to environmental degradation and public health risks.

Waste incineration is a common method of waste disposal in Zambia, particularly in healthcare facilities. However, incineration has potential environmental and health impacts, including the release of toxic pollutants and the creation of a culture of disposal rather than reduction and recycling. Livingstone General Hospital’s waste management practices are inadequate, with an old and poorly maintained incinerator and a lack of adherence to environmental regulations.
To address these challenges, the government and healthcare facilities must invest in alternative methods of waste management, including autoclaving, microwaving, recycling, and landfilling. Additionally, there must be increased public awareness about the importance of proper waste management and the potential health and environmental impacts of poor waste management practices. The government must also strengthen its environmental governance framework, including increasing resources and capacity for the Environmental Management Authority and the Ministry of Health.
