Introduction
Chikankata Mission Hospital, located in the Southern Province of Zambia, has been providing quality healthcare services to the local community for over 60 years. As a reputable healthcare institution, the hospital has always strived to maintain high standards of patient care, hygiene, and environmental sustainability. However, the increasing volume of medical waste generated by the hospital posed a significant challenge to its sustainability goals. In response, the hospital embarked on a quest for sustainable waste management, with a focus on the effective use of incinerators. This news presents a case study on Chikankata Mission Hospital’s experiences with incinerators in Zambia, highlighting the benefits, challenges, and lessons learned in the pursuit of sustainable waste management.
Medical waste, including hazardous and non-hazardous materials, is a significant concern for healthcare facilities worldwide. In Zambia, the lack of adequate waste management infrastructure and regulatory frameworks exacerbates the problem. Medical waste can contaminate soil, water, and air, posing serious health risks to patients, staff, and the surrounding community. The World Health Organization (WHO) estimates that approximately 15% of medical waste is hazardous, requiring specialized handling and disposal.
Chikankata Mission Hospital, with its 200-bed capacity and outpatient departments, generates a substantial amount of medical waste daily. The hospital’s waste stream includes infectious materials, sharps, pharmaceuticals, and non-hazardous waste such as paper, cardboard, and food waste. Prior to the introduction of incinerators, the hospital relied on makeshift disposal methods, including open burning and burying, which posed significant environmental and health risks.
The Introduction of Incinerators
In 2012, Chikankata Mission Hospital introduced its first incinerator, a diesel-fired unit with a capacity to handle 50 kg of waste per hour. The incinerator was designed to burn hazardous and non-hazardous waste, reducing the volume of waste by up to 90%. The hospital’s management recognized the potential benefits of incineration, including:
- Reduced waste volume: Incineration reduces the volume of waste, making it easier to manage and dispose of.
- Pathogen destruction: Incineration destroys pathogens, reducing the risk of infection transmission.
- Environmental protection: Incineration reduces the risk of environmental contamination, protecting soil, water, and air quality.
The hospital’s experience with the first incinerator was positive, with significant reductions in waste volume and improved compliance with regulatory requirements. Encouraged by these results, the hospital upgraded to a more efficient and environmentally friendly incinerator in 2018, a dual-chamber unit with a capacity to handle 100 kg of waste per hour.
Benefits of Incinerators
The introduction of incinerators at Chikankata Mission Hospital has yielded several benefits, including:
- Improved waste management: Incineration has reduced the hospital’s reliance on makeshift disposal methods, minimizing environmental and health risks.
- Increased regulatory compliance: The hospital is now better equipped to comply with national and international regulations governing medical waste management.
- Reduced waste disposal costs: Incineration has reduced the hospital’s waste disposal costs, as the volume of waste sent to landfills has decreased significantly.
- Enhanced patient and staff safety: Incineration has minimized the risk of infection transmission and environmental contamination, creating a safer working environment for staff and patients.
Challenges and Lessons Learned
While the introduction of incinerators has been beneficial, the hospital has faced several challenges, including:
- High operational costs: Incinerators require significant amounts of fuel and maintenance, increasing operational costs.
- Air pollution concerns: Incineration can generate air pollutants, including particulate matter, carbon monoxide, and dioxins, which can have adverse effects on human health and the environment.
- Limited capacity: The hospital’s incinerators have limited capacity, requiring careful waste management planning to ensure efficient operation.
To address these challenges, the hospital has implemented several strategies, including:
- Waste segregation and reduction: The hospital has introduced waste segregation and reduction programs, minimizing the amount of waste generated and ensuring that only necessary waste is incinerated.
- Incinerator maintenance and monitoring: Regular maintenance and monitoring of the incinerators have ensured optimal performance and minimized the risk of air pollution.
- Staff training and awareness: The hospital has provided staff training and awareness programs, emphasizing the importance of proper waste management and incinerator operation.

Chikankata Mission Hospital’s experience with incinerators in Zambia demonstrates the potential benefits and challenges of sustainable waste management in healthcare settings. The use of incinerators has improved waste management practices, reduced waste disposal costs, and enhanced patient and staff safety. However, the hospital has also faced challenges related to operational costs, air pollution concerns, and limited capacity. By implementing strategies to address these challenges, the hospital has optimized the use of incinerators, minimizing environmental and health risks.
As Zambia and other developing countries strive to improve healthcare services and environmental sustainability, the experience of Chikankata Mission Hospital offers valuable lessons. The adoption of incinerators and other sustainable waste management technologies can significantly improve waste management practices, reducing the risk of environmental contamination and infection transmission. Nevertheless, careful planning, maintenance, and monitoring are essential to ensure the effective and safe operation of these technologies.
