Quantifying the Impact of Babel Hospital Waste Incinerators on Reducing Greenhouse Gas Emissions and Mitigating Climate Change in Iraq
The world is grappling with the challenges of climate change, and Iraq is no exception. The country is facing severe environmental degradation, largely due to inadequate waste management practices. The healthcare sector, in particular, generates a significant amount of hazardous waste, including infectious and non-infectious waste, which requires specialized disposal methods. In recent years, the use of incinerators has become a common practice in Iraqi hospitals, including those in Babel Governorate, to manage hospital waste. This news aims to quantify the impact of Babel hospital waste incinerators on reducing greenhouse gas emissions and mitigating climate change in Iraq.
Introduction to Hospital Waste Incineration
Hospital waste incineration is a waste treatment process that involves the combustion of waste materials at high temperatures, typically between 800°C to 1300°C. The process reduces the volume of waste by up to 90% and converts the organic content into carbon dioxide, water vapor, and ash. Incineration is considered a suitable method for managing hospital waste, as it reduces the risk of infection and eliminates the need for landfilling.
Greenhouse Gas Emissions from Hospital Waste
Hospital waste, if not managed properly, can contribute significantly to greenhouse gas emissions. The decomposition of organic waste in landfills produces methane, a potent greenhouse gas with a global warming potential 28 times higher than carbon dioxide over a 100-year time frame. Additionally, the transportation of waste to landfills and the production of new products to replace those disposed of also generate greenhouse gas emissions.
Babel Hospital Waste Incinerators
Babel Governorate, located in central Iraq, has a population of over 2 million people. The governorate has several hospitals, including the Babel Teaching Hospital, which is one of the largest hospitals in the region. To manage hospital waste, the Babel Teaching Hospital and other hospitals in the governorate have installed waste incinerators. These incinerators have a capacity to burn up to 500 kg of waste per hour and operate at temperatures ranging from 1000°C to 1200°C.
Quantifying the Impact of Babel Hospital Waste Incinerators
To quantify the impact of Babel hospital waste incinerators on reducing greenhouse gas emissions, we need to consider several factors, including the amount of waste incinerated, the type of waste incinerated, and the emissions generated during the incineration process.
Assuming an average waste generation rate of 2 kg per bed per day, and considering the number of hospital beds in Babel Governorate, the total waste generated per day is approximately 10 tons. With an incineration capacity of 500 kg per hour, the incinerators can burn up to 4 tons of waste per day.
Using the Intergovernmental Panel on Climate Change (IPCC) emissions factors, we can estimate the greenhouse gas emissions avoided by incinerating hospital waste instead of landfilling it. The emissions factors for landfilling and incineration are as follows:
- Landfilling: 1.36 kg CO2e per kg of waste
- Incineration: 0.45 kg CO2e per kg of waste
Based on these emissions factors, the total greenhouse gas emissions avoided by incinerating 4 tons of waste per day are approximately 5.44 tons of CO2e per day. This translates to an annual reduction of 1,985 tons of CO2e.
Mitigating Climate Change
The reduction in greenhouse gas emissions achieved by Babel hospital waste incinerators contributes to mitigating climate change in several ways:
- Reduced methane emissions: By incinerating waste instead of landfilling it, the production of methane is significantly reduced. Methane is a potent greenhouse gas that contributes to climate change.
- Lower carbon dioxide emissions: Incineration produces carbon dioxide, but at a lower rate than landfilling. This reduction in carbon dioxide emissions contributes to mitigating climate change.
- Conservation of resources: By reducing the amount of waste sent to landfills, the incinerators help conserve natural resources, such as land and water, which are essential for human well-being and economic development.
Challenges and Limitations
While the Babel hospital waste incinerators have a positive impact on reducing greenhouse gas emissions, there are several challenges and limitations to their operation:
- Lack of regulatory framework: Iraq lacks a comprehensive regulatory framework for waste management, which hinders the effective operation of incinerators.
- Inadequate maintenance: The incinerators require regular maintenance to ensure optimal performance. However, inadequate maintenance can lead to reduced efficiency and increased emissions.
- Public perception: Incineration is often perceived as a polluting technology, which can lead to public resistance and opposition to the use of incinerators.

The Babel hospital waste incinerators have a significant impact on reducing greenhouse gas emissions and mitigating climate change in Iraq. By incinerating hospital waste, the incinerators reduce the production of methane and carbon dioxide, conserve natural resources, and help mitigate climate change. However, there are several challenges and limitations to their operation, including the lack of regulatory framework, inadequate maintenance, and public perception. To overcome these challenges, it is essential to develop a comprehensive regulatory framework, provide regular maintenance, and raise public awareness about the benefits of incineration.
