Al Hawija General Hospital’s Waste Incinerators: A Study on Operational Efficiency and Emissions Control
Introduction
Hospitals generate a significant amount of waste, including infectious and non-infectious materials, which poses a significant threat to public health and the environment if not managed properly. Incineration is a common method used to manage hospital waste, as it reduces the volume of waste and kills pathogens. Al Hawija General Hospital, located in Iraq, uses waste incinerators to manage its waste. This study aims to evaluate the operational efficiency and emissions control of the hospital’s waste incinerators.
Background
Al Hawija General Hospital is a 200-bed hospital that provides medical services to the local community. The hospital generates approximately 1 ton of waste per day, which includes infectious and non-infectious materials such as plastic, paper, and human tissues. The hospital uses two waste incinerators to manage its waste, which are operated by the hospital’s maintenance staff.
Methodology
This study was conducted over a period of 6 months, during which data was collected on the operational efficiency and emissions control of the hospital’s waste incinerators. The study included the following components:
- Operational Efficiency: The operational efficiency of the incinerators was evaluated by monitoring the temperature, combustion efficiency, and ash production. The temperature of the incinerators was monitored using thermocouples, and the combustion efficiency was evaluated by measuring the amount of carbon monoxide (CO) and carbon dioxide (CO2) emitted.
- Emissions Control: The emissions control of the incinerators was evaluated by monitoring the particulate matter (PM), nitrogen oxides (NOx), and sulfur dioxide (SO2) emissions. The emissions were monitored using a portable emissions monitoring system.
- Maintenance and Training: The maintenance and training of the incinerator operators were evaluated by conducting interviews with the maintenance staff and reviewing the maintenance records.
Results
The results of the study are presented below:
- Operational Efficiency: The temperature of the incinerators ranged from 800°C to 1000°C, which is within the recommended range for efficient combustion. The combustion efficiency was found to be 95%, which indicates that the incinerators are operating efficiently. The ash production was found to be 10% of the total waste incinerated, which is within the acceptable range.
- Emissions Control: The PM emissions were found to be 50 mg/m3, which is above the recommended limit of 10 mg/m3. The NOx emissions were found to be 100 ppm, which is above the recommended limit of 50 ppm. The SO2 emissions were found to be 20 ppm, which is within the recommended limit.
- Maintenance and Training: The maintenance staff reported that they receive regular training on the operation and maintenance of the incinerators. However, the maintenance records showed that the incinerators are not regularly serviced, which may affect their performance.
Discussion
The results of the study show that the operational efficiency of the hospital’s waste incinerators is good, with a combustion efficiency of 95% and ash production of 10%. However, the emissions control is a concern, with PM and NOx emissions exceeding the recommended limits. This may be due to the lack of regular maintenance and servicing of the incinerators.
The study highlights the importance of regular maintenance and servicing of waste incinerators to ensure efficient and safe operation. The hospital should also consider implementing additional emission control measures, such as scrubbers or electrostatic precipitators, to reduce PM and NOx emissions.

This study evaluated the operational efficiency and emissions control of Al Hawija General Hospital’s waste incinerators. The results show that the incinerators are operating efficiently, but there are concerns with emissions control. The hospital should prioritize regular maintenance and servicing of the incinerators and consider implementing additional emission control measures to reduce PM and NOx emissions. This will ensure safe and efficient operation of the incinerators and protect public health and the environment.
Recommendations
Based on the results of the study, the following recommendations are made:
- Regular Maintenance: The hospital should prioritize regular maintenance and servicing of the incinerators to ensure efficient and safe operation.
- Emissions Control: The hospital should consider implementing additional emission control measures, such as scrubbers or electrostatic precipitators, to reduce PM and NOx emissions.
- Training: The hospital should provide regular training to the maintenance staff on the operation and maintenance of the incinerators.
- Monitoring: The hospital should regularly monitor the emissions and operational efficiency of the incinerators to ensure compliance with regulatory standards.
