Hong Kong Sludge Treatment Plant
Veolia has constructed the largest sludge treatment plant in the world in Hong Kong.Matthias Fekl, Secretary of State for Foreign Trade, and Antoine Frérot, Veolia CEO, opened the largest sewage sludge treatment plant in the world at Hong Kong today. This plant has its own independent water and energy supplies, and treats sludge from eleven sewage stations in the region, covering 7.2 million inhabitants. The plant combines urban ecology and lifestyle, not to mention exceptional architecture.
This new plant is the largest treatment sludge incineration unit in the world, thanks to its installed capacity, with 2,000 tons treated each day by 110 members of personnel. The treatment and incineration technology used reduces waste by 90%, while protecting the natural environment and eliminating sea discharges. Heat and power are generated in sludge treatment, and used for the three spa pools located right next to the plant, and supply 4,000 households. A seawater desalination unit is used to cover site water requirements and 1,000 trees have been planted as part of a carbon compensation programme.Exceptional architecture
Veolia and the French architect, Claude Vasconi, have constructed an innovative building “between waves and hills” entirely built into the Hong King bay environment. This 7-hectare site, known as “T PARK”, was designed to symbolise the "journey from waste to energy" and is part of the “green goals” of the city.
The site comprises:
Converting waste into an energy resource according to the principles of a circular economy
- a recreational and educational centre for the general public, with a 2,800 m² interactive exhibition on sludge treatment;
- a landscaped and ecological garden covering 9,800 m2 reflecting the biodiversity of the bay of Hong Kong - grebes, kingfishers, moorhens, dragonflies and amphibians -;
- a theatre, a café, a spa with three heated pools, and a patio on the roof all look out over Deep Bay and Shenzhen.
With this plant, Veolia has created a solution for the scarcity of fossil fuels and global warming, challenges particularly facing China and Asia.Satisfying environmental priorities and optimising the energy performance of Hong Kong
Over the last two decades, Hong Kong has invested massively in modernising its wastewater treatment plants. Since 1990, the environmental impact of economic growth (+25% annually) has led the Government to respond to 4 main priorities: water treatment and protection; waste management and recycling; reduce noise and improve air quality; optimise energy consumption and performance. In May 2015, the Environment bureau of Hong Kong launched a "Energy Savings Plan for the Urban Environment of Hong Kong 2015- 2025 +
" and announced its goal of reducing energy intensity by 40% by 2025 compared with 2005 figures.
“ This plant is now a benchmark in the water segment and illustrates the sewage stations of the future. The site combines urban ecology and lifestyle with a refined look incorporating the protection of the environment and intense urban development", reiterated Antoine Frérot.
