The Soc Son Waste-to-Energy Plant, located in the Nam Son Waste Treatment Complex in Trung Gia Commune, was officially inaugurated on October 13, 2025.
It stands as the largest waste-to-energy facility in Southeast Asia and the second-largest globally, surpassed only by the plant in Shenzhen, China.
With an investment exceeding 7.5 trillion VND, the project is spearheaded by Thien Y Hanoi Environmental Energy JSC. Constructed on nearly 17.5 hectares, the plant broke ground in 2019 amidst the COVID-19 pandemic and rapidly connected to the national grid by July 2022.
The facility’s phases 1 and 2 are operational, featuring 5 incinerators with a daily capacity of 4,000 tons of waste, a reception capacity of 5,000 tons/day, and 2 turbines generating approximately 60 MW. It adheres to Vietnam’s highest standards and the EU 2010 norms for wastewater, emissions, and ash treatment.
Phase 3 has completed trials, poised to boost total power output to 90 MW upon approval of Power Plan VIII.
Following this success, Thien Y Hanoi Environmental Energy JSC has proposed adding 2 incinerators matching the existing 5 (800 tons/day each), increasing the total to 7 to address previously landfilled waste at Nam Son.
Established on March 15, 2018, Thien Y Hanoi Environmental Energy JSC was founded to develop and operate the Soc Son project in former Soc Son District, with an initial charter capital of 64 million USD.
Shareholders include Soc Son Renewable Energy JSC (6%), Europe Tianying BVBA (Belgium, 66%), and Perfect Ware Holdings Limited (UK, 28%).
As of recent updates, Mr. Li Ai Jun, a Chinese national, serves as the legal representative. The charter capital has risen to 108 million USD, with Mr. Li contributing through Europe Tianying G and Firion Investments SL.
The company’s portfolio includes the Soc Son plant and two additional facilities in Phu Tho, each processing 1,000 tons/day.
