The Thien Y waste incineration plant for electricity generation has basically completed the construction work. Until now, there are only few items that are not yet completed but do not affect the operation of the plant such as painting, equipment installation, etc. At the moment, Phase 1 and phase 2 of the project are operating safely and stably, and expectedly, from May 22 to July 7, the unit will operate the start-up and load operation phase of the plant according to the guideline process of Hitachi Zosen (equipment manufacturing unit). The current waste incineration capacity is 2400 tons/day, as the factory receives garbage of 3,000 tons/day, generating capacity of 2 units is 60MW. The amount of domestic solid waste received by the factory from the beginning of 2023 to May 10, 2023 is about 320,000 tons. The volume of fly ash generated from domestic waste treatment is about 90 tons/day. For a sustainable operation of the business, Thien Y recommends that Hanoi soon pays for the treatment of domestic waste from 2022 to May 10, 2023, at the same time, adjusts the management unit to perform the solid waste treatment service contract, sets a designated landfill for fly ash, and analyse and approve the official waste treatment unit prices.

At 8am, July 25 2023, Vietnam's largest waste incineration plant in Soc Son district (Hanoi) officially connected to the national power grid and operated phase 1. It was expected that about 20 MW of electricity generated from the incineration process would serve the operation of the plant and about 50 MW would be fed into the national grid. The plant operation is divided into 3 phases with a total of 5 incinerators and 3 generating sets. Phase 1 will have 1 incinerator and 1 operating unit, about 1,000 tons of fresh waste would be received by the factory every day. Phase 2 includes 2 incinerators and phase 3 includes 2 more incinerators, which operated in 2022.

Non-stop efforts from the government

In recent years, Hanoi has made tremendous efforts in improving the local environment and standard of livings. In the period 2017-2022, the city treated water pollution in 90 inner city lakes, built 6 domestic wastewater treatment plants with a total capacity of about 276,300m3/day - night, which has treated about 28.8% of the total generated wastewater. The wastewater treatment in industrial zones and clusters is also performing effectively, as 100% of industrial parks and 60.5% of industrial clusters are operating with centralised wastewater treatment stations. Additionally, regarding waste collection, up to now, the suburban area has collected 95-100% of domestic waste, the inner city area has a collection rate of 100%, and hazardous waste treatment reaches 99%.

From now until 2025, Hanoi city will invest in building 8 wastewater treatment plants and craft village waste in districts: Quoc Oai, Me Linh, Hoai Duc, Thuong Tin with a total capital of about 570 billion VND (~$24 millions). There will also be 48 craft village industrial clusters in the districts of: Phuc Tho, Thach That, Quoc Oai, Hoai Duc, Thanh Oai, Thuong Tin, Ung Hoa, Phu Xuyen, Chuong My, Thanh Tri and Ha Dong district with capital amount about 8,900 billion VND (~$380 millions).

In 2023, the city will complete the adjustment of the solid waste treatment planning, ensuring that 100% of domestic waste in the city is collected and treated. Thien Y waste power plant is also expected to operate 100% capacity (4,000m3/day - night). The government will also speed up the construction of Xuan Son incineration plants (Son Tay town) and Dong Ke (Chuong My district) to reduce the pressure of waste treatment by burying.
