The Soc Son Waste-to-Energy (WTE) project is located in Nam Son Waste Treatment Complex and was approved by Hanoi’s administration in late 2017 with a total investment of VND7 trillion ($303 million). Once complete, it will be the largest in Vietnam and the second largest in the world with a capacity of handling 4,000 tons of dry solid waste per day. The project’s investor is Hanoi-based Thien Y Environmental Energy JSC and its contractor, Chinese Metallurgical Group Corporation General Contractor MCC (China). Currently, the biggest WTE project in the world is in Shenzhen, China with a capacity of 5,000 tons per day.

On May 28, the plant received its first garbage trucks passing through the weighing station, officially operating the first phase of receiving and treating garbage after 21 months of construction. For now, the project will continue to be adjusted in terms of technique. When in operation, it is expected to receive 450-500 garbage trucks daily.

An overhead crane operates along rails and has extended arms to mix trash and deliver waste from the storage tank into the incinerator. It is expected that with 4,000 tons of waste incinerated each day, 75 MW of power will be generated. Of that sum, the plant will consume 15-20 percent and sell the rest to Vietnam Electricity Corporation (EVN), the countrys sole power distributor.
The plant has five incinerators and three generator sets. Under favorable conditions, the plant will generate electricity after 15 days of burning waste.It is expected all three generators will operate at once in November this year, said Li Ai Jun, deputy general director of Thien Y Environmental Energy.

A garbage tank that can hold thousands of tons of trash at once. When put into operation, it will be completely closed. Garbage coming here will be kept for about ten days, then transferred to the incinerator. A ventilation fan circulates air in one direction so the odor does not leak.

Hanoi is currently using ten types of garbage trucks of different sizes and loading capacities but as regulated by the WTE plant, each truck must go in, drop the garbage and go out within three minutes.
Work to install the incinerator system and related equipment is underway. After entering the incinerator, garbage will be burned to generate waste heat and ash at the bottom of the furnace. The ash will be used as a raw material for the production of building materials, while the heat is transferred to the generator turbine to produce electricity.
