Construction on the VND 5,000 billion (approximately USD 196 million) Seraphin Plant began in March 2022. It started receiving waste in May and entered commercial power generation in July this year. The facility can process 2,250 tonnes of waste per day and generate 37 MW of electricity using Martin incineration technology from Germany. It currently handles about one-third of Hanoi’s daily household waste, reducing landfill disposal by up to 98 per cent.
By-products from the treatment process are recycled for economic and social development, including electricity fed into the national grid, ash used in precast concrete and non-fired bricks. From 2026, the plant plans to open free tours for residents and students to learn about modern waste treatment and environmental protection in the capital.
In addition to Seraphin, the Soc Son Waste-to-Energy Plant processes 4,000 to 5,000 tonnes daily, producing 90 MW of electricity. The city also plans to excavate old buried waste for treatment, converting landfill sites into public parks.
In June, the municipal people’s council approved a plan to build another waste-to-energy plant in Nam Son, Soc Son District, to handle daily waste, legacy waste and sludge, while improving the local environment.
