On October 13, at the Nam Son Waste Treatment Complex (Soc Son District, Hanoi), the Hanoi People's Committee coordinated with Thien Y Environmental Energy Joint Stock Company to organize the inauguration ceremony of the Soc Son Waste-to-Energy Plant.
This is the second largest waste-to-energy plant in the world, after Shenzhen (China), with the capacity to process 4,000-5,000 tons of waste per day, equivalent to about 70% of Hanoi's waste. He said that Hanoi currently has two waste-to-energy plants that meet international standards, but the total capacity can only process about 6,000 tons out of more than 7,600 tons of waste generated daily. The rest still has to be buried, putting great pressure on treatment areas such as Nam Son and Xuan Son.
The Soc Son Waste-to-Energy Plant has a total investment capital of more than VND7,000 billion (equivalent to USD320 million), invested by Thien Y Hanoi Environmental Energy Joint Stock Company, with an area of nearly 17.5 hectares. The project started construction in 2019, during the COVID-19 pandemic, and officially connected to the national grid in July 2022.
The inauguration of Soc Son waste-to-energy plant.The plant is designed with 5 incinerators and 3 generators, operating in 3 phases. The first phase includes one incinerator and one generator, with a processing capacity of 1,000 tons/day and night. The next two phases increase the capacity to 4,000-5,000 tons/day, equivalent to nearly 5,500 tons of wet waste, with a maximum power output of 90 MW.
The technology used here allows for the burning of unsorted household waste. The system for treating exhaust gas, leachate and ash is automatically monitored and meets Vietnamese and European standards. Since its trial operation, the plant has treated more than 1.2 million tons of household waste and about 245,000 m³ of leachate, significantly reducing pressure on Hanoi's two major landfills.
