Addressing accumulated waste and reducing pressure on the urban environment.

According to Decision No. 775/QD-UBND dated February 13, 2026, the project will be implemented in two phases. Phase 2 focuses on treating long-buried waste, which is a source of leachate and toxic emissions.

Processing the accumulated waste helps reduce the risk of soil, water, and air pollution. At the same time, the area of the landfill after processing can be repurposed for public infrastructure or urban development.

With Hanoi's rapid urbanization and the sharp increase in household waste, pressure on landfills is growing ever greater. Waste-to-energy incineration is seen as a viable alternative to help reduce reliance on landfills.

Efficiency from Phase 1 and the energy problem

According to city figures, phase 1 of the plant processed nearly 5 million tons of waste, generating nearly 2 billion kWh of power. Its receiving capacity reached approximately 5,000 tons per day, equivalent to nearly 70% of the city's total household waste.

Waste-to-energy is a technology that converts waste into electric energy through high-temperature incineration, then recovers the heat to generate electricity. This technology helps reduce waste volume while utilizing energy from waste materials.

The expansion of the plant will not only increase processing capacity but also add power to the urban energy system.

Circular economy and resource regeneration

The project is designed as an integrated initiative, simultaneously addressing multiple challenges related to the environment, land, and resources.

Waste, after being processed, can be transformed into power or construction materials. This aligns with the circular economy model, where waste becomes an input for a new production cycle.

From a resource perspective, reclaiming land from landfills provides clean land in the context of Hanoi's lack of development space.

The shift to waste-to-energy incineration reflects a general trend in many major cities around the world. This technology requires strict emission control systems to ensure environmental standards are met.

In terms of policy, Hanoi is gradually reducing the rate of landfilling and increasing the rate of treatment using modern technology. This is consistent with the orientation of sustainable development and energy transition.

The expansion project of the Soc Son waste-to-energy plant demonstrates Hanoi's new approach to waste management. Waste is no longer a burden but becomes a resource if processed properly.

The message "For a Green Capital, a Journey of Resource Regeneration" reflects the orientation of transforming waste into economic values, contributing to building a sustainable city in the long term.
