Factors Influencing the Performance of Chilenje First Level Hospital Waste Incinerators: A Study of Operational, Technical, and Socio-Economic Aspects
The management of healthcare waste is a critical issue worldwide, particularly in developing countries where resources are limited. In Zambia, the Chilenje First Level Hospital is one of the major healthcare facilities in the country, generating a significant amount of waste that requires proper disposal. Incineration is one of the most common methods used to dispose of healthcare waste, but its performance is influenced by various factors. This study aims to investigate the operational, technical, and socio-economic aspects that affect the performance of incinerators at Chilenje First Level Hospital.
Introduction
Healthcare waste management is a significant concern in Zambia, as it poses a risk to public health and the environment. The Chilenje First Level Hospital, located in Lusaka, is one of the busiest healthcare facilities in the country, providing medical services to a large population. The hospital generates a substantial amount of waste, including infectious and non-infectious waste, sharps, and pharmaceutical waste. Incineration is the primary method used to dispose of healthcare waste at the hospital, but its performance is affected by various factors.
Literature Review
Previous studies have highlighted the importance of proper healthcare waste management in preventing the spread of infectious diseases and protecting the environment. Incineration is a widely used method for disposing of healthcare waste, but its performance is influenced by operational, technical, and socio-economic factors. Operational factors include the type and quantity of waste, incinerator design, and maintenance. Technical factors include the temperature and residence time of the incinerator, as well as the type of fuel used. Socio-economic factors include the availability of resources, training, and awareness among healthcare workers.
Methodology
This study used a mixed-methods approach, combining both qualitative and quantitative data collection and analysis methods. The study was conducted at Chilenje First Level Hospital, where data was collected through observations, interviews, and questionnaires. The sample size consisted of 30 healthcare workers, including nurses, doctors, and waste management staff. The data was analyzed using descriptive statistics and thematic analysis.
Operational Factors
The study found that the type and quantity of waste generated at the hospital affected the performance of the incinerators. The hospital generated a significant amount of infectious waste, including sharps and pharmaceutical waste, which required special handling and disposal. The incinerators were designed to handle a specific type and quantity of waste, but the hospital’s waste generation exceeded the incinerator’s capacity. This led to frequent breakdowns and reduced the incinerator’s efficiency.
Technical Factors
The study revealed that the technical aspects of the incinerators, including the temperature and residence time, were critical in determining their performance. The incinerators were designed to operate at a temperature of 1000°C, but the study found that the actual temperature was often lower, ranging from 800-900°C. This reduced the incinerator’s ability to completely burn the waste, resulting in incomplete combustion and the release of toxic pollutants. The residence time, which is the time the waste spends in the incinerator, was also found to be inadequate, leading to incomplete combustion.
Socio-Economic Factors
The study found that socio-economic factors, including the availability of resources, training, and awareness among healthcare workers, played a significant role in the performance of the incinerators. The hospital faced challenges in maintaining the incinerators due to limited resources, including funding and personnel. The healthcare workers also lacked training and awareness on proper waste management and incinerator operation, leading to incorrect usage and maintenance.
Discussion
The study’s findings highlight the importance of considering operational, technical, and socio-economic factors in the performance of incinerators at Chilenje First Level Hospital. The hospital’s waste generation exceeded the incinerator’s capacity, leading to frequent breakdowns and reduced efficiency. The technical aspects of the incinerators, including temperature and residence time, were critical in determining their performance. The socio-economic factors, including resource availability, training, and awareness, also played a significant role in the incinerators’ performance.

The performance of incinerators at Chilenje First Level Hospital is influenced by a range of operational, technical, and socio-economic factors. The hospital’s waste generation, incinerator design, and maintenance, as well as the technical aspects of the incinerators, including temperature and residence time, are critical in determining their performance. The socio-economic factors, including resource availability, training, and awareness, also play a significant role. To improve the performance of the incinerators, the hospital needs to address these factors, including increasing the incinerator’s capacity, improving maintenance, and providing training and awareness to healthcare workers.
Recommendations
- Increase incinerator capacity: The hospital should consider increasing the incinerator’s capacity to handle the large amount of waste generated.
- Improve maintenance: The hospital should improve maintenance of the incinerators, including regular cleaning and repairs.
- Provide training and awareness: The hospital should provide training and awareness to healthcare workers on proper waste management and incinerator operation.
- Improve resource availability: The hospital should improve resource availability, including funding and personnel, to ensure proper maintenance and operation of the incinerators.
