T·PARK is a state-of-the-art sludge treatment facility specifically design to provide an innovative and eco-friendly solution for the problem of sewage sludge disposal in Hong Kong.
The facility integrates a power station, a spa resort and a sludge treatment facility. With its architecturally distinctive wave-like façade, it is the first facility of its kind in Hong Kong, and one of the largest sludge incinerators in the world.
It utilises fluidised bed incineration technology, capable of burning 2,000 tonnes of sludge every day and uses the excess heat energy to generate electricity. At full operational capacity, an excess of 2MW of power is available daily. The building was completed in late 2014 and operation commenced in early 2015.

Waste to energy
T·PARK incinerates the sludge produced at Hong Kong’s 11 sewage treatment works and the foul wet sludge that would otherwise be dumped in landfill, will be reduced to ash, representing a reduction of about 90% by mass.
As the sludge burns, energy is conducted in the form of steam, which is then transformed into electricity to power the entire plant’s operation. When running at full capacity, it can produce up to 2MW of surplus electricity for the public power grid. This means that not only is the T·PARK entirely self-sufficient, it also supplies its surplus electricity back into the electricity grid. Through the sophisticated flue gas treatment methods, any remaining air output is clean for environmental emission.
Waste to energy solutionsBIM
The entire design process followed a Building Information Modelling (BIM) process that established complex three dimensional models for coordination, drawings production, operational and maintenance simulation, as well as material take-off for the design and construction of the facility. It has facilitated the design, analysis and coordination throughout the project - from delivery routes for major equipment, pipe layout and routing through to the positioning of the plant during construction on site.
Building information modelling (BIM)Delivering an efficient structural solution
The building’s flowing roofline reflects and integrates the seaview in front and ridge lines at the back, blending with the surrounding scenery. Achieving this dramatic architectural roof structure posed considerable design challenges. The 400m-long roof spans over, and unites, the two incinerator plants and the centrally located administration tower. Our structural designers adopted a modular design, which improved the ‘buildability’ of the roof and was key to achieving the overall construction programme for the building.
Holistic approach for sustainability
T·PARK is highly sustainable. Almost 70% of the site is landscaped or has green roof coverage. Potable and processed water is supplied by processing sea water through a desalination plant that is capable of producing up to 600m³/day. Rainwater is collected for non-potable use, while waste water is treated and re-used on site, including for the irrigation of the soft landscaping. The use of advanced recycling processes means there will be zero discharge of wastewater from the facility, thus protecting the environment.
