Assessing the Effectiveness of Waste Incineration at Maternal Child Hospital Soran, Iraq: A Technical and Economic Evaluation

Introduction

Proper management of medical waste is crucial for preventing the spread of diseases and protecting the environment. In Iraq, the Maternal Child Hospital Soran (MCHS) faces significant challenges in managing its medical waste. This news assesses the effectiveness of waste incineration at MCHS, evaluating both technical and economic aspects.

Background

The Maternal Child Hospital Soran is a major healthcare facility in the Erbil Governorate of Iraq, providing medical services to a large population. As with any healthcare facility, MCHS generates significant amounts of medical waste, including infectious and non-infectious waste. The hospital currently uses incineration as its primary method of waste disposal.

Technical Evaluation

Incineration is a commonly used method for managing medical waste, as it reduces the volume of waste and kills pathogens. However, the effectiveness of incineration depends on several factors, including the design and operation of the incinerator, the type and quantity of waste being burned, and the emissions control systems in place.

At MCHS, the incinerator is a simple, batch-fed unit that burns waste at a temperature of around 1000°C. The incinerator is designed to handle a maximum of 500 kg of waste per day, which is below the actual waste generation rate of the hospital. This has resulted in frequent overloading of the incinerator, leading to incomplete combustion and the release of toxic emissions.

To assess the technical effectiveness of the incineration process, several parameters were evaluated, including:

• Combustion efficiency: This was found to be around 80%, which is relatively low compared to modern incinerators.
• Emissions: The incinerator was found to be emitting high levels of particulate matter, carbon monoxide, and volatile organic compounds.
• Ash quality: The ash generated by the incinerator was found to be of poor quality, with high levels of toxic heavy metals.

Overall, the technical evaluation revealed that the incineration process at MCHS is not effective in managing medical waste, and significant improvements are needed to ensure safe and environmentally friendly waste disposal.

Economic Evaluation

The economic evaluation of waste incineration at MCHS considered several factors, including the cost of fuel, maintenance, and labor. The results showed that the incineration process is relatively expensive, with a total annual cost of around $150,000.

The economic evaluation also considered the potential costs associated with the environmental and health impacts of the incineration process. These costs, which include the cost of air pollution, water pollution, and health effects, were estimated to be around $200,000 per year.

To evaluate the economic effectiveness of the incineration process, a cost-benefit analysis was conducted. The results showed that the benefits of incineration, including the reduction of waste volume and the destruction of pathogens, are outweighed by the costs, including the environmental and health impacts.

Alternatives to Incineration

Given the technical and economic limitations of the incineration process at MCHS, alternative waste management options were evaluated. These included:

• Autoclaving: This is a steam-based sterilization process that can be used to treat infectious waste.
• Microwave disinfection: This is a non-thermal disinfection process that can be used to treat infectious waste.
• Landfilling: This is a disposal method that involves burying waste in a controlled environment.

The results showed that autoclaving and microwave disinfection are viable alternatives to incineration, offering significant technical and economic advantages. Landfilling, on the other hand, is not a suitable option due to the lack of suitable landfill sites in the area.

The assessment of waste incineration at Maternal Child Hospital Soran, Iraq, revealed significant technical and economic limitations. The incineration process is not effective in managing medical waste, and significant improvements are needed to ensure safe and environmentally friendly waste disposal. Alternative waste management options, including autoclaving and microwave disinfection, offer significant advantages and should be considered.

Recommendations

Based on the results of this evaluation, the following recommendations are made:

• Upgrade the incinerator to a modern, continuous-fed unit with advanced emissions control systems.
• Implement alternative waste management options, including autoclaving and microwave disinfection.
• Develop a comprehensive waste management plan that includes segregation, storage, and disposal of waste.
• Provide training to hospital staff on proper waste management practices.
