Ulaanbaatar, October 14, 2025 /MONTSAME/. Construction of a new facility to process, dry, and incinerate sludge from the Central Wastewater Treatment is scheduled to begin next year, according to the Office of the Mayor of the Capital.
The project is part of the 24 mega initiatives aimed at advancing the development of Ulaanbaatar. A feasibility study has been completed and approved by the Construction Development Center, and preparations are currently underway to announce a construction tender.
The plant will be built through a public-private partnership in the 20th khoroo of Songinokhairkhan District, occupying a 40,000-square-meter site located in front of the Ulaanbaatar city wastewater treatment facility. Designed to meet international standards and environmental regulations, the plant will be capable of processing an average of 250 cubic meters of sludge per day and incinerating up to 238 tonnes per day. Additionally, 843,200 cubic meters of sludge will be recycled annually. Emissions from the incineration process will be treated using a high-tech air purification system to minimize environmental impact.
Officials emphasized the importance of properly processing and disposing of sludge from the Central Treatment Plant to reduce soil, water, and air pollution. The project also aims to promote waste reuse, generate energy, and create new employment opportunities.
