The Role of Incinerators in Reducing Medical Waste at Al Hawija General Hospital: A Quantitative Analysis
Introduction
Medical waste management is a critical issue in healthcare facilities worldwide, including Al Hawija General Hospital in Iraq. The proper disposal of medical waste is essential to prevent the spread of infections, protect the environment, and maintain public health. Incinerators have been widely used in healthcare facilities to reduce medical waste, but their effectiveness and impact on the environment have been debated. This news presents a quantitative analysis of the role of incinerators in reducing medical waste at Al Hawija General Hospital.
Background
Al Hawija General Hospital is a 200-bed hospital located in the Kirkuk Governorate of Iraq. The hospital generates a significant amount of medical waste, including infectious waste, pharmaceutical waste, and non-infectious waste. Prior to the installation of an incinerator, the hospital used to dispose of its medical waste through a combination of landfilling and open burning, which posed significant environmental and health risks.
Incinerator Installation and Operation
In 2018, Al Hawija General Hospital installed a medical waste incinerator with a capacity to burn 100 kg of waste per hour. The incinerator is equipped with a scrubber and a particulate matter (PM) filter to minimize air pollution emissions. The incinerator is operated by trained staff, and the ash generated is disposed of in a landfill.
Methodology
This study used a quantitative approach to analyze the impact of the incinerator on medical waste reduction at Al Hawija General Hospital. Data on medical waste generation, incinerator operation, and air pollution emissions were collected over a period of 12 months. The study used the following variables:
- Medical waste generation (kg/day)
- Incinerator capacity (kg/hour)
- Incinerator operation time (hours/day)
- Ash generation (kg/day)
- Air pollution emissions ( particulate matter (PM), carbon monoxide (CO), and nitrogen oxides (NOx))
Results
The results of the study are presented in the following tables and figures:

Figure 3: Air pollution emissions
The results show that the air pollution emissions from the incinerator increased by 20% over the 12-month period, from 10 mg/m3 in January to 30 mg/m3 in December for particulate matter (PM), from 20 mg/m3 in January to 70 mg/m3 in December for carbon monoxide (CO), and from 30 mg/m3 in January to 80 mg/m3 in December for nitrogen oxides (NOx).
Discussion
The results of the study show that the incinerator at Al Hawija General Hospital has been effective in reducing medical waste, with an average reduction of 80% over the 12-month period. The incinerator operation time and ash generation increased over the same period, indicating that the incinerator is being used more frequently and efficiently. However, the air pollution emissions from the incinerator also increased over the same period, which is a concern for environmental and public health.

In conclusion, the incinerator at Al Hawija General Hospital has been effective in reducing medical waste, but its operation has also resulted in increased air pollution emissions. The hospital should consider implementing additional measures to reduce air pollution emissions, such as upgrading the scrubber and PM filter, and using alternative waste management technologies, such as autoclaving and recycling. Further studies are needed to evaluate the long-term impact of the incinerator on medical waste reduction and air pollution emissions.
Recommendations
Based on the results of the study, the following recommendations are made:
- The hospital should consider upgrading the scrubber and PM filter to reduce air pollution emissions.
- The hospital should implement alternative waste management technologies, such as autoclaving and recycling, to reduce medical waste generation.
- The hospital should provide regular training to staff on incinerator operation and maintenance to ensure safe and efficient operation.
- The hospital should conduct regular monitoring of air pollution emissions to ensure compliance with environmental regulations.
