Energy Recovery from Waste Incineration at Ibn Al Baitar Private Hospital in Iraq: A Feasibility Study
The increasing amount of waste generated by healthcare facilities, such as hospitals, has become a significant concern in Iraq and worldwide. Ibn Al Baitar Private Hospital, located in Iraq, is no exception to this issue. With a growing population and an ever-increasing demand for medical services, the hospital faces the challenge of managing its waste effectively. One potential solution to this problem is energy recovery from waste incineration. This news aims to investigate the feasibility of implementing an energy recovery system from waste incineration at Ibn Al Baitar Private Hospital in Iraq.
Introduction
Waste management is a critical issue in the healthcare sector, particularly in developing countries like Iraq. The lack of proper waste management practices can lead to environmental and health hazards. Incineration is a common method of waste disposal in healthcare facilities, as it reduces the volume of waste and sterilizes it, making it safer for the environment. However, incineration also produces energy, which can be recovered and utilized to reduce the hospital’s dependence on non-renewable energy sources.
Background
Ibn Al Baitar Private Hospital is a leading healthcare facility in Iraq, providing medical services to a large number of patients. The hospital generates a significant amount of waste, including hazardous and non-hazardous materials. The current waste management practice at the hospital involves incineration, which is carried out in a dedicated incinerator on site. However, the energy generated from the incineration process is not recovered, and the hospital relies on traditional energy sources, such as diesel generators, to meet its energy demands.
Energy Recovery from Waste Incineration
Energy recovery from waste incineration involves the use of heat generated from the incineration process to produce steam, which can then be used to generate electricity or provide heating and cooling to the hospital. This process can be achieved through the use of a heat recovery steam generator (HRSG) or an organic rankine cycle (ORC) system. The HRSG system uses the heat from the incineration process to produce steam, which is then used to drive a turbine and generate electricity. The ORC system, on the other hand, uses a working fluid to convert the heat from the incineration process into electricity.
Feasibility Study
To determine the feasibility of implementing an energy recovery system from waste incineration at Ibn Al Baitar Private Hospital, several factors need to be considered, including:
- Waste Quantity and Quality: The amount and type of waste generated by the hospital need to be determined to assess the potential energy generation. The hospital generates approximately 500 kg of waste per day, consisting of 70% non-hazardous and 30% hazardous materials.
- Incineration Capacity: The capacity of the existing incinerator needs to be assessed to determine its potential to generate energy. The incinerator has a capacity of 200 kg/h and operates for 8 hours a day.
- Energy Demand: The hospital’s energy demand needs to be determined to assess the potential energy savings. The hospital consumes approximately 1000 kWh of electricity per day.
- Technological Options: The technological options available for energy recovery from waste incineration need to be evaluated, including HRSG and ORC systems.
- Economic Feasibility: The economic feasibility of the project needs to be assessed, including the initial investment, operating costs, and potential revenue from energy sales.
Results
Based on the feasibility study, the following results were obtained:
- Potential Energy Generation: The potential energy generation from the waste incineration process was estimated to be approximately 120 kWh/h, based on the incinerator’s capacity and operating hours.
- Energy Savings: The potential energy savings from implementing an energy recovery system were estimated to be approximately 20% of the hospital’s total energy consumption.
- Technological Options: Both HRSG and ORC systems were found to be suitable for energy recovery from waste incineration at the hospital, with the HRSG system being more cost-effective.
- Economic Feasibility: The initial investment for the project was estimated to be approximately $200,000, with a payback period of 5 years, based on the potential energy savings and revenue from energy sales.

The feasibility study has shown that energy recovery from waste incineration at Ibn Al Baitar Private Hospital in Iraq is technically and economically feasible. The implementation of an energy recovery system can help reduce the hospital’s dependence on non-renewable energy sources, decrease its energy costs, and contribute to a more sustainable waste management practice. However, further studies are needed to assess the environmental impact and social acceptance of the project.
Recommendations
Based on the results of the feasibility study, the following recommendations are made:
- Implementation of an Energy Recovery System: The hospital should consider implementing an energy recovery system from waste incineration, using a HRSG or ORC system.
- Waste Management Practice: The hospital should review its waste management practice to ensure that it is optimized for energy recovery.
- Energy Efficiency Measures: The hospital should consider implementing energy efficiency measures to reduce its energy consumption and maximize the potential energy savings from the energy recovery system.
- Monitoring and Evaluation: The hospital should establish a monitoring and evaluation system to track the performance of the energy recovery system and assess its impact on the environment and the hospital’s energy consumption.
