Hong Kong T▪Park

STF, Sludge Treatment, T-Park, Hong Kong

Urban, prosperous and diverse, Hong Kong embodies the quintessential modern city in every aspect, including its large volumes of sewage sludge. With a vision to promote circular economy, Veolia offers an effective solution for Hong Kong’s sludge problem and a truly unique, next-generation sludge treatment concept.

As a model city, Hong Kong is under the spotlight to lead the way in sustainable practices that balance urban ecology and lifestyle.

Traditionally, all sewage sludge in Hong Kong goes to the landfills, putting pressure on the waste handling capacity of a city where three landfills serve the needs of more than 7 million inhabitants. Hong Kong needs transformative solutions not only to optimise its waste reduction and management, but to propel the city towards greater sustainability and resilience.

The Veolia Solution

In Hong Kong, Veolia built a world-class wastewater sludge incineration unit, providing energy efficient treatment of sludge from the city’s wastewater treatment plants. But the cutting-edge facility goes far beyond just that. It is a truly innovative complex that combines a variety of advanced technologies, and is fully autonomous and self-sufficient in energy and water.

T-Park, one of the world’s largest and most technologically advanced sludge treatment facilities, treats up to 2,000 tons of sludge per day. The facility is fully energy and water self-sufficient: the thermal energy from incineration generates enough electricity to power the entire Plant and be allocated for public use, and a seawater desalination plant on site produces 600m3 of drinking water per day, fulfilling all of the plant’s water usage needs. The treatment process reduces 90% of the sludge volume, easing the pressure on Hong Kong’s landfills.

Complete with a visitor gallery, lecture theatre, sea view cafeteria, spa pools, observation platform and vast green areas, the facility adds a public engagement and education component to the city’s sustainability efforts.

Veolia’s world-leading design and technologies combine to create the sludge treatment plant of the future, shaping Hong Kong’s waste-to-energy journey.
