T.PARK is the world’s largest wastewater sludge incineration plant, self-sufficient and designed to convert all of Hong Kong’s sludge into space-saving ash and renewable energy.
As the first large-scale waste-to-energy facility in Hong Kong, T.PARK is a key environmental infrastructure project in the city’s “Climate Action Plan 2030+.” The plant uses fluidized bed incineration to process wastewater sludge from the large sewage treatment works in the city. With a total capacity of 2,000 tons of sludge per day, it will meet the needs of the city beyond 2030. Previously, the wet and energy-rich sludge was dumped in landfills. With incineration at T.PARK, the residual ash uses 90% less landfill volume, and CO2 emissions from landfilling are significantly reduced. The process also generates renewable energy to power the plant and export to the city’s grid.
The entire facility has been built as a model for sustainability. Drinking water is provided by a desalination plant and rainwater is collected for non-potable uses. All wastewater generated within the facility is treated on site for reuse, resulting in zero effluent discharge to the sea. There is also an Environmental Education Centre equipped with leisure, educational, and landscaped facilities, including a spa, exhibition halls, upcycling showrooms, wetland garden, and bird sanctuary.
237,000 tons of CO2 emissions will be reduced every year when the plant reaches full capacity
The challenge
Hong Kong’s sewage production is expected to grow significantly due to a growing population. A further challenge is that the city’s buildings account for 90% of electricity consumption and 60% of the carbon emissions.
Co-benefits
Economic The plant will generate 80 million kWh of electricity annually to power the plant and for export to the grid, generating cost savings and powering 4,000 households.
Environmental The facility has been designed to the highest green building standards as a model for other buildings in the city.
Social The Environmental Education Centre at T.PARK aims to encourage sustainable living via educational and recreational initiatives. There is also an eco-cafe that employs socially disadvantaged members of the Tuen Mun District.
Health At the facility, double-door design and negative air pressure inside the sludge delivery bays help to prevent bad odors and dust pollution.
About Hong Kong
Hong Kong is an autonomous territory on China’s south coast. It has an area of 1,104 km2, and with a population of around 7.2 million, Hong Kong is the world’s fourth most densely populated country or territory. Hong Kong is one of the world’s most significant financial centres, with the highest Financial Development Index score and consistently ranks as the world’s most competitive and freest economic entity. Nicknamed “Pearl of the Orient”, Hong Kong is renowned for its deep natural harbour, which boosts the world’s 5th busiest port and its impressive skyline, with the most skyscrapers in the world.
