How Mongolia’s Incinerator is Turning Trash into Energy

Mongolia is a country with a rapidly growing population and economy, leading to an increase in waste generation. In 2017, the World Bank estimated that Mongolia’s capital city, Ulaanbaatar, produced around 1,240 tons of waste per day. With this increase in waste generation, there has been growing concern about the impact of waste on the environment and public health. In response to this challenge, Mongolia has been developing innovative solutions to manage its waste, including the construction of the first waste-to-energy facility in the country. This incinerator project is not only turning trash into energy but also contributing to a cleaner and more sustainable environment for Mongolia.
The waste-to-energy facility, known as the Ulaanbaatar Solid Waste Incineration Plant, was completed in 2018 with the support of the Japan International Cooperation Agency (JICA). The plant uses advanced incineration technology to convert municipal solid waste into electricity, reducing the volume of waste and generating clean energy. The facility has a capacity to process 800 tons of waste per day, which accounts for a significant portion of Ulaanbaatar’s daily waste production.
The incineration process starts with the collection and transportation of the waste to the facility. The waste is then sorted to remove any recyclable materials, such as plastics, metals, and paper, which are sent for recycling. The remaining non-recyclable waste is then incinerated at high temperatures, typically between 850 and 1100 degrees Celsius. This process generates heat, which is used to produce steam and drive a turbine to generate electricity. The plant has the capacity to produce 140,000 megawatt-hours of electricity per year, which can power approximately 164,000 households in Ulaanbaatar.
One of the key benefits of the waste-to-energy facility is the reduction of landfill waste. Prior to the facility’s operation, Ulaanbaatar was heavily reliant on landfills to dispose of its waste, which resulted in environmental pollution and health risks for nearby communities. Landfilling also contributes to the production of methane, a potent greenhouse gas that contributes to climate change. The incineration of waste diverts a significant portion of Ulaanbaatar’s waste from landfills, reducing the environmental impacts associated with landfilling.
Furthermore, the generation of electricity from waste also contributes to a more sustainable energy mix for Mongolia. By utilizing waste as a fuel source, the country reduces its dependence on traditional fossil fuels, contributing to lower greenhouse gas emissions and improving air quality in Ulaanbaatar. The electricity generated from the incineration process is also more reliable and stable compared to intermittent renewable energy sources, providing a consistent source of power for the city.
In addition to producing electricity, the waste-to-energy facility also generates other valuable by-products from the incineration process. The ash generated from the incineration of waste can be used as a construction material, such as in road construction and landfill cover. This reduces the need for virgin materials and supports sustainable construction practices. Furthermore, the heat generated from the incineration process can be used for district heating, providing a reliable and efficient source of heat for Ulaanbaatar’s residents during the cold winter months.
The construction and operation of the Ulaanbaatar Solid Waste Incineration Plant have been a significant step forward for Mongolia in improving its waste management practices and moving towards a more sustainable and circular economy. The facility is a testament to the country’s commitment to addressing the challenges of waste management while harnessing the potential of waste as a valuable resource for energy and materials.
FAQs
Q: Is incineration a safe process for managing waste?
A: Modern waste-to-energy facilities use advanced incineration technology, which is designed to operate at high temperatures to ensure complete combustion of waste and minimize emissions of harmful pollutants. The facilities are equipped with emission control systems, such as scrubbers and filters, to remove pollutants from the exhaust gases before they are released into the atmosphere. Furthermore, the ash produced from the incineration process is carefully managed to ensure it does not contribute to environmental contamination.
Q: What are the environmental benefits of waste-to-energy facilities?
A: Waste-to-energy facilities help to reduce the volume of waste sent to landfills, which minimizes the environmental impacts associated with landfilling, such as methane emissions and leachate contamination. Additionally, the generation of electricity from waste contributes to a more sustainable energy mix, reducing the reliance on traditional fossil fuels and lowering greenhouse gas emissions. The facilities also support the recycling of materials and the recovery of valuable resources from waste.
Q: How does the incineration process contribute to air quality?
A: The incineration process is designed to operate at high temperatures, which ensures complete combustion of waste and reduces the emissions of harmful pollutants. The facilities are equipped with advanced emission control systems to remove pollutants from the exhaust gases before they are released into the atmosphere. As a result, waste-to-energy facilities can contribute to improved air quality compared to traditional waste management practices, such as open burning and landfilling.
Q: What can be done to ensure the sustainable operation of waste-to-energy facilities?
A: To ensure the sustainable operation of waste-to-energy facilities, it is essential to prioritize waste reduction, recycling, and other waste management practices before considering incineration. Additionally, it is important to implement proper environmental and social impact assessments, engage with local communities, and adhere to strict environmental and safety regulations. Continuous monitoring and maintenance of the facilities are also crucial to ensure that they operate in an environmentally responsible manner.
