Waste Incineration and Environmental Sustainability at Lewanika General Hospital, Mongu: A Review of Best Practices

Waste Incineration and Environmental Sustainability at Lewanika General Hospital, Mongu: A Review of Best Practices

Lewanika General Hospital, located in Mongu, Zambia, is one of the largest healthcare facilities in the Western Province. The hospital provides essential medical services to the local community, including emergency care, surgery, and outpatient services. However, the generation of medical waste is an inherent consequence of healthcare activities, and Lewanika General Hospital is no exception. The hospital produces a significant amount of waste, including hazardous materials such as sharps, pharmaceuticals, and infectious waste. The management of this waste is crucial not only for the protection of public health but also for environmental sustainability.

Waste incineration is a common method used for managing medical waste in many healthcare facilities, including Lewanika General Hospital. Incineration involves the combustion of waste at high temperatures, resulting in the reduction of waste volume and the destruction of pathogens. However, incineration also has environmental implications, including the release of air pollutants and the potential for soil and water contamination.

Environmental Sustainability and Waste Incineration

Environmental sustainability is a critical consideration in the management of medical waste. The World Health Organization (WHO) defines environmental sustainability as “the ability of a system to maintain its functions and services over time, while minimizing its impact on the environment.” In the context of waste incineration, environmental sustainability involves minimizing the negative environmental impacts associated with incineration, such as air pollution and waste disposal.

At Lewanika General Hospital, waste incineration is carried out using a simple incinerator that burns waste at high temperatures. However, the incinerator is not equipped with pollution control devices, such as scrubbers or electrostatic precipitators, which can reduce the release of air pollutants. As a result, the incineration process at Lewanika General Hospital may be contributing to environmental pollution, including the release of particulate matter, carbon monoxide, and volatile organic compounds.

Best Practices for Waste Incineration and Environmental Sustainability

To minimize the environmental impacts associated with waste incineration, several best practices can be implemented at Lewanika General Hospital. These include:

1. Waste segregation and sorting: Separating non-hazardous from hazardous waste can reduce the volume of waste that requires incineration. Non-hazardous waste can be disposed of through safer methods, such as landfilling or recycling.
2. Use of pollution control devices: Installing pollution control devices, such as scrubbers or electrostatic precipitators, can reduce the release of air pollutants from the incinerator.
3. Monitoring of incinerator emissions: Regular monitoring of incinerator emissions can help identify areas for improvement and ensure compliance with environmental regulations.
4. Training and capacity building: Providing training and capacity building for healthcare workers on waste management and incineration can ensure that waste is handled and disposed of safely and sustainably.
5. Alternative waste management methods: Exploring alternative waste management methods, such as autoclaving or microwave disinfection, can reduce the reliance on incineration and minimize environmental impacts.

Challenges and Opportunities for Waste Incineration and Environmental Sustainability

Despite the importance of environmental sustainability in waste incineration, several challenges exist at Lewanika General Hospital. These include:

1. Limited resources: The hospital faces financial and personnel constraints, which can limit the implementation of best practices for waste incineration and environmental sustainability.
2. Lack of infrastructure: The hospital’s waste management infrastructure is inadequate, with limited storage and disposal facilities for hazardous waste.
3. Regulatory framework: The regulatory framework for waste management in Zambia is weak, which can make it difficult to ensure compliance with environmental regulations.

However, opportunities also exist for improving waste incineration and environmental sustainability at Lewanika General Hospital. These include:

1. Partnerships and collaborations: Partnering with international organizations, non-governmental organizations, and private sector companies can provide access to technical assistance, funding, and expertise.
2. Training and capacity building: Providing training and capacity building for healthcare workers can improve waste management practices and reduce environmental impacts.
3. Community engagement: Engaging with the local community can raise awareness about the importance of environmental sustainability and promote behavior change.
