The expansion of the Soc Son Waste-to-Energy Plant at the Nam Son Integrated Waste Treatment Complex in Hanoi is expected to process approximately 10 million tons of previously landfilled waste, while restoring the site for future public developments, including parks, a golf course, and ecological green spaces.

Expansion Project to Address Legacy Waste and Increase Power Generation Capacity

Under Decision No. 775/QD-UBND issued by the Hanoi People’s Committee, the Soc Son Waste-to-Energy Plant has been approved for development in two phases. Phase 2 focuses on treating millions of tons of waste that have accumulated at the Nam Son landfill over many years, one of Hanoi’s largest waste disposal sites. The expansion project officially broke ground in April 2026 and is being developed by Thien Y Hanoi Environmental Energy Joint Stock Company at the Nam Son Integrated Waste Treatment Complex.

Currently, Phase 1 of the plant processes approximately 5,000 tons of waste per day, generating 90 MW of electricity. Once the expansion is completed, the facility is expected to treat an additional 1,600 tons of landfilled waste daily, increasing its total power generation capacity to 135 MW. The project has a total investment of approximately VND 12.999 trillion, of which VND 5.830 trillion is allocated to the expansion phase. Commercial operation is targeted for Q4 2027.

Processing 10 Million Tons of Legacy Waste Over the Next Decade

According to local authorities, approximately 10 million tons of waste remain buried at the Nam Son landfill.

Under the proposed plan, the existing waste will be excavated, sorted, and processed alongside newly collected municipal waste using waste-to-energy technology. Materials unsuitable for incineration will be evaluated for recycling into fertilizers or construction materials.

The project aims to eliminate the entire stockpile of legacy waste over the next 10 years, reducing reliance on landfill disposal, minimizing environmental risks associated with landfill leachate, and gradually restoring the surrounding environment.

Before the Soc Son Waste-to-Energy Plant began operations, approximately 5,500 tons of waste were landfilled at Nam Son every day. Today, that figure has fallen dramatically to around 100–500 tons per day, significantly easing pressure on Hanoi’s waste management system.

Transforming the Former Landfill into Parks and a Golf Course

Following the completion of waste treatment and environmental restoration, the Nam Son landfill is planned to be repurposed for public and recreational use.

According to the proposed development plan, the reclaimed land could be transformed into public parks, a golf course, ecological areas, and other community facilities. This vision is intended not only to improve the urban landscape but also to create long-term value from land that has served as a waste disposal site for decades.

However, before this transformation can take place, the project must complete the remediation of old landfill areas and leachate reservoirs. These efforts are considered essential for restoring the site’s environmental quality and preparing the land for future development.
